Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Public Key Encryption (Asymmetric Key Encryption)
 
05:06
In public key encryption, two different keys are used to encrypt and decrypt data.One is the public key and other is the private key. These two keys are mathematically related. They come as a pairs. The public key encryption is also called asymmetric key encryption because two different keys are used. Public key algorithm is used for different purpose from private key algorithm. It is used for verification and authentication. In this video, I will use an example to demonstrate how to use public key.

Digital Signature: https://www.youtube.com/watch?v=TmA2QWSLSPg&t=2s Digital signature is used for authentication, non-repudiation and data integrity, but there is one weakness of digital signature alone: man-in-the-middle attack. Digital certificates are electronic credentials issued by a trusted third party. A digital certificate not only verifies the identity of the owner, but also verifies that the owner owns the public key. In this video, I will demonstrate why digital signature has weakness and how digital certificate comes in place to make sure digitally signed document must come originally from the claimed sender.

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 doesnโ€™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 senderโ€™s private key before being attached to the document. When the document is received, the recipient decrypts the digest using the senderโ€™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.

Public Key Infrastructure Fundamentals - Bart Preneel
 
01:31:53
The function of a public key infrastructure (PKI) is to ensure secure delivery and management of public keys. Alternative trust models lead to different key architectures. Public keys are published by means of digitally signed certificates. A private key may be compromised, in which case the certificate containing the corresponding public key must be revoked. Many revocation methods are in current use. Publication of Certificate Revocation Lists (CRLs) and checking with an Online Certificate Status Protocol (OCSP) responder are best established. Learning objectives + learn the components of a public key infrastructure. + understand key delivery and management mechanisms. A lecture by Bart Preneel at SecAppDev 2013 in Leuven, Belgium. Professor Bart Preneel of KU Leuven heads the COSIC (COmputer Security and Industrial Cryptography) research group. His main research area is information security with a focus on cryptographic algorithms and protocols as well as their applications to both computer and network security, and mobile communications. He teaches cryptology, network security and coding theory at the K.U.Leuven and was visiting professor at the Ruhr Universitaet Bochum (Germany), the T.U.Graz (Austria), the University of Bergen (Norway), and the Universiteit Gent (Belgium). In '93-'94 he was a research fellow at the University of California at Berkeley. He has taught intensive courses around the world. He undertakes industrial consulting (Mastercard International, S.W.I.F.T., Proton World International,...), and participates in the work of ISO/IEC JTC1/SC27/WG2.

A digital signature is equivalent to a handwritten signature in paper, and a digital signature serves three basic purposes.

Private Key Encryption (Symmetric Key Encryption)
 
04:52
In private key encryption, data is encrypted using a single same key that only the sender and the receiver know. That is why private key encryption is also called symmetric key encryption because the same key is used during both encryption and decryption of the transmitted data. In this video, I will also use an example to demonstrate the process of using private key encryption. Two different methods -stream encryption and block encryption- of private key algorithm are also depicted with animation.
