Elliptic curve cryptography is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. One of the main benefits in comparison with non-ECC cryptography is the same level of security provided by keys of smaller size. Elliptic curves are applicable for encryption, digital signatures, pseudo-random generators and other tasks. They are also used in several integer factorization algorithms that have applications in cryptography, such as Lenstra elliptic curve factorization. This video is targeted to blind users.

Bernstein | Tanja Lange There are several different standards covering selection of curves for use in elliptic-curve cryptography (ECC). Each of these standards tries to ensure that the elliptic-curve discrete-logarithm problem (ECDLP) is difficult. ECDLP is the problem of finding an ECC user's secret key, given the user's public key. Unfortunately, there is a gap between ECDLP difficulty and ECC security. None of these standards do a good job of ensuring ECC security. There are many attacks that break real-world ECC without solving ECDLP. The core problem is that if you implement the standard curves, chances are you're doing it wrong: Your implementation produces incorrect results for some rare curve points. Your implementation leaks secret data when the input isn't a curve point. Your implementation leaks secret data through branch timing. Your implementation leaks secret data through cache timing. These problems are exploitable by real attackers, taking advantage of the gaps between ECDLP and real-world ECC. Secure implementations of the standard curves are theoretically possible but very hard. Most of these attacks would have been ruled out by better choices of curves that allow simple implementations to be secure implementations. This is the primary motivation for SafeCurves, http://safecurves.cr.yp.to/. The SafeCurves criteria are designed to ensure ECC security, not just ECDLP security.

Signing and claiming ownership of data is a basic act in cyber space, especially to approve financial transactions, and verify critical instructions. The prevailing signatures today are based on algorithmic complexity, which is essentially a cryptanalytic minefield - vulnerable to weaponized math. Alternatively, we can rely on lavish use of randomness, and resurrect pre-complexity solutions. The forgotten Lamport signature is attracting new interest.

Hello Friends, in this lecture we have taught that, The Rabin cryptosystem is an asymmetric cryptographic technique, whose security, like that of RSA, is related to the difficulty of factorization. However the Rabin cryptosystem has the advantage that the problem on which it relies has been proved to be as hard as integer factorization, which is not currently known to be true of the RSA problem. It has the disadvantage that each output of the Rabin function can be generated by any of four possible inputs; if each output is a ciphertext, extra complexity is required on decryption to identify which of the four possible inputs was the true plaintext.

Speaker: Roland van Rijswijk-Deij, SURFnet Over the past decade, we have seen the gradual rollout of DNSSEC across the name space, with adoption growing slowly but steadily. While DNSSEC was introduced to solve security problems in the DNS, it is not without its own problems. In particular, it suffers from two big problems: 1) Use of DNSSEC can lead to fragmentation of DNS responses, which impacts the availability of signed domains due to resolvers being unable to receive fragmented responses and 2) DNSSEC can be abused to create potent denial-of-service attacks based on amplification. Arguably, the choice of the RSA cryptosystem as default algorithm for DNSSEC is the root cause of these problems. RSA signatures need to be large to be cryptographically strong. Given that DNS responses can contain multiple signatures, this has a major impact on the size of these responses. Using elliptic curve cryptography, we can solve both problems with DNSSEC, because ECC offers much better cryptographic strength with far smaller keys and signatures. But using ECC will introduce one new problem: signature validation - the most commonly performed operation in DNSSEC - can be up to two orders of magnitude slower than with RSA. Thus, we run the risk of pushing workload to the edges of the network by introducing ECC in DNSSEC. This talk discusses solid research results that show 1) the benefits of using ECC in terms of solving open issues in DNSSEC, and 2) that the potential new problem of CPU use for signature validation on resolvers is not prohibitive, to such an extent that even if DNSSEC becomes universally deployed, the signature validations a resolver would need to perform can easily be handled on a single modern CPU core. Based on these results, we call for an overhaul of DNSSEC where operators move away from using RSA to using elliptic curve-based signature schemes.

When using anonymous networks like Tor or I2P, one problem is always how to prevent spam/DoS attacks when you cannot distinguish one entity from another, and hence cannot limit them without either compromising their anonymity by requiring registration of some kind, or requiring captcha-like challenges which are time consuming to implement and usually only a temporary solution at best. Here I introduce a new kind of authentication system based on homomorphic properties of elliptic curve cryptography and zero knowledge proofs called "Linkable Ring Signatures". It allows one to add their public key to a larger group of existing public keys, called a "ring", and sign using the entire "ring" of keys + private key in such a way that no one can tell which private key has signed the message, but can mathematically verify that it was one private key corresponding to one of the public keys in the ring. On top of that, it allows a verifier that only has access to the public keys in the ring to make sure that for any one [message, ring] pair, a private key has only signed it once - duplicate signatures for the same message are detectable. This allows for limiting interactions from any party holding one of these access keys (to say, one message per minute per key), without the party losing any anonymity as their signature is indistinguishable from any other party in the ring. Furthermore, because ring signatures use a cryptographic component called "zero knowledge proofs", signing reveals zero information about the private key - hence no matter how many signatures are generated, it is impossible to use them to try to forge messages or fingerprint/bruteforce the signer key. The proof of this will be shown in the talk. In this talk I will walk through the cryptographic primitives that make this possible, and show a demo service on Tor/I2P that implements this scheme to make an anti-spam anonymous forum.

We look at the mathematical difference between the two cryptosystems, showing why ECC is faster and harder than RSA, but also very energy efficient hence its unique advantage in the mobile space. We show how to use ECC in your Java and Android applications.

If you like this video and want to support me, go this page for my donation crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 6 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. Digital signatures are used for authentication, integrity checking and non-repudiation. Development of quantum computers threatens the security of currently used digital signature algorithms such as Rivest–Shamir–Adleman (RSA) and Elliptic Curve Digital Signature Algorithm (ECDSA). Cryptographers developed a variety of quantum-resistant alternatives of which hash based signatures are the most promising. Hash based signatures are based on so called One Time Signatures (OTS). The term implies that a single public/private key pair must only be used once. Otherwise, an attacker is able to reveal more parts of the private key and spoof signatures. In 1979 Leslie Lamport created a method to construct digital signatures using only cryptographically secure one way hash functions. This method is called the Lamport signature or Lamport One Time Signature (OTS) scheme. Other One Time Signature schemes are the Merkle OTS and Winternitz OTS. The Lamport One Time Signature scheme is very easy to understand and is VERY LOOSELY comparable to Winternitz OTS. For simplicity's sake I will be using the Lamport One Time Signature scheme explaining why you should never reuse an IOTA address for outgoing transactions. Alice uses a random number generator and produces two pairs of 256 random numbers, total 512 numbers. Each random number is 256 bits in size. These random numbers forms the private key. Each of the 512 random numbers are separately hashed, using for example SHA-256. These hashed random numbers forms the public key. Alice has a document (or transaction data) which is hashed using SHA-256. The document hash is of course 256 bits long: 101..011 Alice wants to create a digital signature for her document. She applies the following procedure: - Loop thru each bit (n) of the hash from 0-255. - If the bit is a 0, publish the nth number from pair 0. - If the bit is a 1, publish the nth number from pair 1. - When all bits are looped, destroy all unused numbers from pair 0 and 1. This produces a sequence of 256 random numbers. The digital signature is a sequence of 256 random numbers. After the digital signature is created, delete all unused numbers from the private key. The digital signature consist half of the private key, the other 256 random numbers are still unknown and thus nobody can create signatures that fit other message hashes. Alice sends her document, together with the corresponding digital signature and public key to Bob. Bob wants to verify Alice's document signature. He first hashes the document using SHA-256. The document hash is again: 101..011 Bob follows the same steps when Alice created the digital signature, but instead uses the public key. Bob produces a sequence of 256 hashes picked from Alice's public key. Bob now hashes each of the random number in the digital signature. If both sequence of hash numbers match then the signature is ok. The Lamport signature creates a digital signature which reveals part of the private key. The private key has 512 numbers and using it once will reveal 256 numbers. Using the private key twice weakens the security of the scheme again by half. The probability of an attacker being able to successfully forge a signature for a given message increases from 1/(2^256) to 1/(2^128). A third signature using the same key would increase the probability of a successful forgery to 1/(2^64) and a fourth signature to 1/(2^32), and so on. Please note IOTA's signature scheme is based on the Winternitz One Time Signature (WOTS) scheme and is NOT the same as the Lamport signature scheme. However by using the Lamport One Time Signature scheme I am trying to give you a very simplistic understanding why you should never reuse an IOTA address for outgoing transactions.

For decades, all laptops have come with a TPM. Now with Microsoft forcing the transition to the next generation, Linux faces a challenge in that all the previous TPM 1.2 tools don’t work with 2.0. Having to create new tools for TPM 2.0 also provides the opportunity to integrate the TPM more closely into our current crypto systems and thus give Linux the advantage of TPM resident and therefore secure private keys. This talks will provide the current state of play in using TPM 2.0 in place of crypto sticks and USB keys for secure key handling; including the algorithm agility of TPM 2.0 which finally provides a support for Elliptic Curve keys which have become the default recently. This talk will provide an overview of current TSS (Trusted computing group Software Stack) for TPM 2.0 implementation on Linux, including a discussion of the two distinct Intel and IBM stacks with their relative strengths and weaknesses. We will then move on to integration of the TSS into existing crypto system implementations that allow using TPM resident keys to be used with common tools like openssl, gnutls, gpg, openssh and gnome-keyring. We will report on the current state of that integration including demonstrations of how it works and future plans. The ultimate goal is to enable the seamless use of TPM resident keys in all places where encrypted private keys are currently used, thus increasing greatly the security posture of a standard Linux desktop.

First Name: Jerry Last Name: Kott Title: Security Enhancements in Cincom® VisualWorks® 8.3 Abstract: The upcoming release Cincom VisualWorks 8.3 includes several security enhancements. In this presentation, Jerry will give an overview of what they are and how application developers can take full advantage of Cincom’s pluggable, platform-independent security framework. Among others, topics will include: • Added support for Authenticated Encryption with Additional Data (AEAD). This family of algorithms uses Advanced Encryption Standard (AES) block cipher as the base encryption algorithm, and applies Galois/Counter Mode (GCM) as the block chaining mechanism for data larger than a single block. Examples of use in both OpenSSL libcrypto and Windows BCrypt.dll cryptographic libraries and their interoperability. • Added support for Elliptic Curve cryptography on Windows, with a discussion of the limitations imposed by different versions of Windows. • High-level discussion of Elliptic Curve Diffie-Hellman (ECDH) key exchange algorithm and Elliptic Curve Digital Signature Algorithm (ECDSA), and how Cincom Smalltalk™ solves the lack of usable implementation in early versions of these algorithms on Windows. • An overview of newly added cipher suites to the TLSv1.2 protocol • Current status and plans for TLSv1.3 implementation Bio: Jerry Kott, a senior software engineer, has been with Cincom Systems, Inc. now for nine years. Jerry is a valuable member of the Protocols team responsible for network protocols, security and web application development components of the Cincom Smalltalk Foundation. With Cincom® ObjectStudio® and Cincom VisualWorks both built on the same Foundation, this engineering group is responsible for critical improvements that enhance both products. Specifically, Jerry brings a vast knowledge of network protocols and security to this team, instrumental in enhancing those components in Cincom Smalltalk. In his talk, Jerry will be discussing the latest Security Enhancements in Cincom VisualWorks 8.3. Prior to joining Cincom, Jerry worked as a Smalltalk consultant in a variety of industries including finance, insurance, telecommunications, manufacturing and entertainment. Throughout his career, Jerry has used most of the Smalltalk dialects. He first met Smalltalk/V in his native Czechoslovakia in 1988 while writing his Masters theses at the Faculty of Mathematics and Physics, Charles University of Prague. The political upheaval of 1988/1989 led Jerry to leave Czechoslovakia, and after a year in Austria, his family settled in Canada. While working as a programmer analyst at the TD Bank in Toronto, he was reintroduced to Smalltalk in 1993—this time with the intent of staying with it for good. Jerry’s recollection of his falling in love with Smalltalk can be summed up like this: 1. Day one: This is weird, no source code file? 2. Day two: This is interesting; I can inspect live objects and send messages to them! 3. Day three: This is great! I never want to use any other language! Jerry and his wife also recently got 450 programmers to “bite” on Cincom Smalltalk at Battlesnake 2017 where they came in second place with their Medusa algorithm. BattleSnake 2017 is a programming competition that was recently held in Victoria, BC, where teams of students and developers build web-based AIs for the classic arcade game “Snake.” While many platforms were used in developing these algorithms by other competitors, Jerry and his wife built their impressive algorithm using Cincom Smalltalk. When not programming in Smalltalk, Jerry uses his passion for photography and film by helping independent filmmakers as a cinematographer. He occasionally dabbles as an associate producer and assistant director. Jerry is also a member of Juan de Fuca Search and Rescue, a volunteer emergency response team that services the rugged western coastline of Vancouver Island off the West Coast of Canada. He recently started practicing with his dog Cindy to be accepted to the training program of British Columbia Search Dog Association. He lives in Victoria, British Columbia.

Most modern cryptography, and public-key crypto in particular, is based on mathematical problems that are conjectured to be infeasible (e.g., factoring large integers). Unfortunately, standard public-key techniques are often too inefficient to be employed in many environments; moreover, all commonly used schemes can in principle be broken by quantum computers. This talk will review my recent work on developing new mathematical foundations for cryptography, using geometric objects called lattices. Compared to more conventional proposals, lattice-based schemes offer a host of potential advantages: they are simple and highly parallelizable, they can be proved secure under mild worst-case hardness assumptions, and they remain unbroken by quantum algorithms. Due to the entirely different underlying mathematics, however, realizing even the most basic cryptographic notions has been a major challenge. Surprisingly, I will show that lattice-based schemes are also remarkably flexible and expressive, and that many important cryptographic goals can be achieved --- sometimes even more simply and efficiently than with conventional approaches. Some of our schemes provide interesting twists on old and cherished cryptographic notions, while others introduce entirely new concepts altogether.

Internet traffic today is encrypted at a rate of between 80% and 90%. While encryption is a great benefit to securing web traffic, it also presents a problem for inspecting that traffic. Many organizations need to send traffic through security devices/services to ensure they are not allowing malicious traffic into their network. But this presents a problem of organizing and managing encryption keys in addition to slowing down the user experience. In this video, John outlines these issues and explains why they are a problem. Stay tuned for the follow-up video where we outline a solution to this very common problem!

Quantum computers are a fundamentally different sort of computer that take advantage of aspects of quantum physics to solve certain sorts of problems dramatically faster than conventional computers can. While the Quantum Computers will be very useful in various ways, they can create problems in some ways. Specifically, if large quantum computers can be built then they may be able to break the asymmetric cryptographic primitives that are currently used in TLS, the security protocol behind HTTPS. Quantum computers exist today but, for the moment, they are small and experimental, containing only a handful of quantum bits. It's not even certain that large machines will ever be built, although Google, IBM, Microsoft, Intel and others are working on it. Adiabatic quantum computers, like the D-Wave computer that Google operates with NASA, can have large numbers of quantum bits, but currently solve fundamentally different problems. However, a hypothetical, future quantum computer would be able to retrospectively decrypt any internet communication that was recorded today, and many types of information need to remain confidential for decades. Thus even the possibility of a future quantum computer is something that we should be thinking about today. The study of cryptographic primitives that remain secure even against quantum computers is called “post-quantum cryptography”. Google has announced an experiment in Chrome where a small fraction of connections between desktop Chrome and Google's servers will use a post-quantum key-exchange algorithm in addition to the elliptic-curve key-exchange algorithm that would typically be used. By adding a post-quantum algorithm on top of the existing one, Google is able to experiment without affecting user security. The post-quantum algorithm might turn out to be breakable even with today's computers, in which case the elliptic-curve algorithm will still provide the best security that today’s technology can offer. Alternatively, if the post-quantum algorithm turns out to be secure then it'll protect the connection even against a future, quantum computer. Google's aims with this experiment are to highlight an area of research that it believes to be important and to gain real-world experience with the larger data structures that post-quantum algorithms will likely require. There are many post-quantum algorithms available. Google selected a post-quantum algorithm named "New Hope” for this experiment.

The existence of libraries with nice, user-friendly interfaces is one of the most important factors when choosing a programming language. And while there are lots of books about how to write idiomatic libraries in other languages, finding the same information for Rust is more difficult. With this in mind, this talk will present several techniques that help developers take advantage of all that Rust has to offer and create idiomatic APIs: From implementing conversion traits and session types to using custom iterators and decorating built-in types.
