Digital Signatures and Digital Certificates
 
11:26
This video explains the purpose of digital signatures and how they work. It begins by reviewing encryption and decryption using an asymmetric pair of keys, and then explains the significance of this when it comes to digital signatures, namely that it doesn’t matter which of the key pair is made public and which is kept private. The video then illustrates the digital signing process. Specifically, the creation of a hash value for the document (also known as a digest) using a hash algorithm such as SHA256 (which was created by the National Security Agency). It shows how document digest is then encrypted using the sender’s private key before being attached to the document. When the document is received, the recipient decrypts the digest using the sender’s public key. The recipient also recalculates the hash. If the hash values match, the recipient can be confident that document has not been tampered with in transit. The role of a certification authority is also covered. A certification authority issues its customer with a special file called a digital certificate which binds their public key to identifying information. This video also mentions the importance of digital signatures which it comes to cryptocurrencies. A cryptocurrency such as Bitcoin requires a secure mechanism for updating its decentralised ledger.

BSides DC 2018 - Bypassing Port-Security In 2018: Defeating MacSEC and 802.1x-2010
 
51:12
Existing techniques for bypassing wired port security are limited to attacking 802.1x-2004, which does not provide encryption or the ability to perform authentication on a packet-by-packet basis [1][2][3][4]. The development of 802.1x-2010 mitigates these issues by using MacSEC to provide Layer 2 encryption and packet integrity checks to the protocol [5]. Since MacSEC encrypts data on a hop-by-hop basis, it successfully protects against the bridge-based attacks pioneered by the likes of Steve Riley, Abb, and Alva Duckwall [5][6]. In addition to the development of 802.1x-2010, improved 802.1x support by peripheral devices such as printers also poses a challenge to attackers. Gone are the days in which bypassing 802.1x was as simple as finding a printer and spoofing address, as hardware manufacturers have gotten smarter. In this talk, we will introduce a novel technique for bypassing 802.1x-2010 by demonstrating how MacSEC fails when weak forms of EAP are used. Additionally, we will discuss how improved 802.1x support by peripheral devices does not necessarily translate to improved port-security due to the widespread use of weak EAP. Finally, we will consider how improvements to the Linux kernel have made bridge-based techniques easier to implement and demonstrate an alternative to using packet injection for network interaction. We have packaged each of these techniques and improvements into an open source tool called Silent Bridge, which we plan on releasing at the conference.

event page: https://vlab.org/events/open-source-processors/ brochure: https://vlab.org/wp-content/uploads/2018/09/VLAB-Flyer-Open-Source-Processors.pdf Tuesday, September 18, 2018 Stanford Faculty Club - Stanford University 439 Lagunita Drive, Stanford, CA 94305 ------------------------------- Moderator Linley Gwennap, President, The Linley Group Panelists Krste Asanovic, Co-Founder and Chief Architect, SiFive Art Swift, VP Marketing and Business Development, Esperanto Technologies John Heinlein, Vice President, Chief of Staff to the CEO, ARM Stefan Dyckerhoff, Managing Director, Sutter Hill Ventures ------------------------------- The open-source approach to developing new technologies is entering a new realm, with the potential to change an entire industry. For years, open-source has lived exclusively in the software domain. From Linux to GitHub, open-source software has become a powerful way to bring new products and solutions to market. This open-source transformation in software is now making its way to silicon, with far-reaching implications. Open-source has the potential to be as big a game-changer in silicon as it has been in software. Companies like Sifive and Esperanto are already commercializing new architectures based on the open-source approach, and new open-source communities like the RISC V consortium are having a huge impact. In this event, our panel will discuss the promise of open-source CPU architectures and the challenges faced in building complete system-on-a-chip (SoC) products around an open-source Instruction Set Architecture (ISA). What will motivate chip companies and customers to embrace open-source hardware? What ecosystem components are needed for successful commercialization? Which domains will benefit by embedding an open-architecture? What business models can succeed in this new ecosystem?

Leveraging Blockchain for Identity and Authentication in IoT is good for Security - AppSecUSA 2017
 
37:13
Leveraging Blockchain for Identity and Authentication in IoT is good for Security Since the beginning of the internet, attempts have been made to solve the problem of privacy and security. Every effort has had challenges of inconvenience, cost and insecurity. How do we prove our identity? Blockchain technology and its mutual distributed ledgers (MDL) cannot be altered and allow people and companies to record, validate and track transactions throughout a network of decentralized computer systems. These MDLs are databases with a time stamped audit trail. By leveraging this technology, an app on our device will hash our identifying information and insert this into the public Blockchain. Anytime you need to authenticate to another service or user, you share the information which is then sent through the algorithm and checked against the Blockchain. Once authenticated, your information for identification is not needed again. If the hashed information is decentralized and provides interoperability. Personal information never leaves the device and is not stored on a centralized server. Taking the personal data, hashing it and then discarding everything but the hashes of our personal data allows the network to accept the information in the same manner as our ID cards. These Blockchains open the door to innovation and enables more interoperability connecting various distributed services. There can be 2 unique MDLs; one to hold the encrypted documents and a separate ledger that will hold encryption key access which are folders encompassing our identity, health or other qualifying records. Driver’s license bureaus can provide us a digitally signed copy of our driver’s license that we control. We then offer controlled usage to entities that need to inspect the documents, the information recorded on the MDL. This use of immutable ledger can become the accepted modality of the future. Speakers Donald Malloy Chairman, OATH Donald Malloy is the Chairman of OATH, The Initiative for Open Authentication. OATH is an industry alliance that has opened the authentication market from proprietary systems to an open source standard based architecture promoting ubiquitous strong authentication. - Managed by the official OWASP Media Project https://www.owasp.org/index.php/OWASP_Media_Project

DEF CON 21 - Phorkus and Evilrob - Doing Bad Things to 'Good' Security Appliances
 
40:28
Doing Bad Things to 'Good' Security Appliances PHORKUS (MARK CAREY) CHIEF SCIENTIST, PEAK SECURITY EVILROB (ROB BATHURST) THAT GUY The problem with security appliances is verifying that they are as good as the marketing has lead you to believe. You need to spend lots of money to buy a unit, or figure out how to obtain it another way; we chose eBay. We now have a hardened, encrypted, AES 256 tape storage unit and a mission, break it every way possible! We're going to dive into the finer points of the pain required to actually evaluate and disassemble a harden security appliance. We'll be delving into such fun topics as epoxy melting, de-soldering, ROM chip reading, FGPA configuration recreation, Verilog decoding, recovering the various key strands that keep the device/data secure, and any other topics we end up straying into. Phorkus (Mark Carey) (@PeakSec) is a professional Security Engineer with over 18 years of experience in the areas of Information Technology, Rapid Development Lifecycle, Long Term Development Lifecycle, Computer Security, and Research/Development Innovation. He is a partner in Peak Security Inc (www.peaksec.com) where he serves as a Principal Security Consultant and Chief Scientist. Mark has developed many security tools used throughout the corporate and government sectors. Mark has co-authored Network Auditing with Nessus (second edition), and has published internal white-papers for many government agencies.

Glenn Greenwald: Edward Snowden, NSA, Activism, Democracy & Freedom
 
25:03
In this speech, Glenn Greenwald reveals his experience with Edward Snowden and Laura Poitras in 2013 at Hong Kong before they revealed the highly classified NSA documents to the public. Greenwald also talks about the history of activism and pays tribue to personalities such as Rosa Park, Hans and Sophie Scholl. Other topics that he surfaces in-depth include the reaction of the US government to these revelations, signficance of Edward Snowden's courage & the challenges that we face in the future. BIO: Glenn Edward Greenwald is an American lawyer, journalist and author. In June 2013 Greenwald became widely known after The Guardian published the first of a series of reports detailing United States and British global surveillance programs, based on classified documents disclosed by Edward Snowden. The series on which Greenwald worked along with others won the 2014 Pulitzer Prize for Public Service. His reporting on the National Security Agency (NSA) won numerous other awards around the world, including top investigative journalism prizes from the George Polk Award for National Security Reporting,the 2013 Online Journalism Awards, the Esso Award for Excellence in Reporting in Brazil for his articles in O Globo on NSA mass surveillance of Brazilians (becoming the first foreigner to win the award), the 2013 Libertad de Expresion Internacional award from Argentinian magazine Perfil, and the 2013 Pioneer Award from the Electronic Frontier Foundation. His work on the NSA files was in part the subject of the film Citizenfour, which won the 2014 Academy Award for Best Documentary. Greenwald appeared onstage at the Oscar ceremony with the film's director, Laura Poitras, as she accepted the award.

We do the entire thing , first we show the digital signatures for our Key (purchased through N code )(Class 2 )...then we inmstall secure sign software Then we take a sample PDF document and apply our signature Voila , that's it This is how you would be checking for Digital signature certificates in your system Please ensure that that you have downloaded the issuing agency drivers compatible to your Operating system. For example , if you have bought the DSC from n Code , then don't forget to install the drivers from n Code ....if you have purchased from TCS , don't forget to download the certificate drivers from TCS etc etc Until you do this , you wont be able to see the certificate in the system and thus put it to use for signing files , returns , documents etc etc Hope this immensely practical Tutorial helps , Let Knowledge be Practical , Peace , Amlan Dutta

Peter Warren Singer: "Cybersecurity and Cyberwar: What Everyone Needs to Know" | Talks at Google
 
58:52
Cybersecurity and CyberWar discusses the cybersecurity issues that challenge everyone: politicians wrestling with everything from cybercrime to online freedom; generals protecting the nation from new forms of attack while planning new cyberwars; business executives defending firms from once unimaginable threats; lawyers and ethicists building new frameworks for right and wrong. In Cybersecurity and CyberWar, New York Times best-selling author Peter W. Singer and noted cyber expert Allan Friedman team up to provide the kind of easy-to-read, deeply informative resource book that has been missing on this crucial issue of 21st century life. The book is structured around the key question areas of cyberspace and its security: how does it work and why does it matter? Also discussed are the important (and entertaining) issues and characters of cybersecurity, from the "Anonymous" hacker group and the Stuxnet computer virus to the new cyber units of the Chinese and US militaries. Peter W. Singer is a Senior Fellow and the Director of the 21st Century Defense Initiative at the Brookings Institution.

DEF CON 21 - Jason Staggs - How to Hack Your Mini Cooper
 
20:06
How to Hack Your Mini Cooper: Reverse Engineering Controller Area Network (CAN) Messages on Passenger Automobiles JASON STAGGS GRAD STUDENT AND RESEARCH ASSISTANT, UNIVERSITY OF TULSA This presentation introduces the underlying protocols on automobile communication system networks of passenger vehicles and evaluates their security. Although reliable for communication, vehicle protocols lack inherit security measures. This work focuses strongly on controller area networks (CANs) and the lack of authentication and validation of CAN messages. Current data security methods for CAN networks rely on the use of proprietary CAN message IDs along with physical boundaries between the CAN bus and the outside world. As we all know, security through obscurity is not true security. These message IDs can be reverse engineered and spoofed to yield a variety of results. This talk discusses methods for reverse engineering proprietary CAN messages. These reverse engineered messages are then injected onto the CAN bus of a 2003 Mini Cooper with the help of cheap Arduino hardware hacking. Additionally, a proof of concept will be demonstrated on how to build your own rogue CAN node to take over a CAN network and potentially manipulate critical components of a vehicle. The proof of concept demonstrates taking full control of the instrument cluster using the reverse engineering methods presented. Jason Staggs is currently a graduate student in computer science and a security research assistant at the Institute for Information Security (iSec) at The University of Tulsa. He also is involved with The University of Tulsa's Crash Reconstruction Research Consortium (TU-CRRC) where he occasionally gets to hack and wreck a variety of vehicles. Before attending graduate school, Jason worked as a cyber-security analyst for a leading information security firm, True Digital Security in Tulsa, OK. Jason holds a Bachelors degree in Information Assurance and Forensics from Oklahoma State University along with several industry certifications. His research interests include network intrusion detection systems, digital forensics, critical infrastructure protection, and reverse engineering.

Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work! 2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example. 3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

DEF CON 21 - Daniel Selifonov - A Password is Not Enough
 
45:05
A Password is Not Enough: Why disk encryption is broken and how we might fix it DANIEL SELIFONOV Since the publication of the cold boot attack on software disk encryption 5 years ago, there has been little progress on developing countermeasures and implementing defenses in the disk encryption technologies already in wide use. Furthermore, many users of full disk encryption have physical security habits that fall outside the security models of disk encryption software and thus are more vulnerable than they realize. After examining a set of effective, easily executable, attacks on off- the-shelf disk encryption, and contextualizing them in x86 system architecture, we examine recent research on means of mitigating these attacks. By integrating AES new instructions, x86 debugging registers, encrypted RAM, IOMMU, and the TPM into a combined encryption system, the difficulty of executing a successful attack is raised significantly. We will examine the construction of this system in detail, and, at a higher level, the role of full disk encryption in assuring meaningful security in the face of physical access. Source to an experimental version of the system will be made available. Daniel Selifonov has consulted for a handful of research oriented startups since 2007, and built systems for information technology where security was considered throughout design and implementation, rather than as an afterthought. His research interests in security include reverse engineering, applied cryptography, client side security, and user acceptable information system design. He believes that businesses, no matter the size, should have the tools to defend themselves without getting in the way of core operations, and that existing tools and building blocks require too much expert input to implement correctly.
