A cryptographic protocol is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to ...
One of the earliest applications of a non-commutative algebraic structure for cryptographic purposes was the use of braid groups to develop cryptographic protocols. Later several other non-commutative structures like Thompson groups , polycyclic groups , Grigorchuk groups , and matrix groups have been identified as potential candidates for ...
The sender of an encrypted (coded) message shares the decryption (decoding) technique only with the intended recipients to preclude access from adversaries. The cryptography literature often uses the names "Alice" (or "A") for the sender, "Bob" (or "B") for the intended recipient, and "Eve" (or "E") for the eavesdropping adversary. [6]
SPORE, the Security Protocols Open Repository, is an online library of security protocols with comments and links to papers. Each protocol is downloadable in a variety of formats, including rules for use with automatic protocol verification tools. All protocols are described using BAN logic or the style used by Clark and Jacob, and their goals ...
Cryptographic protocols — the communication protocols designed and available to provide computer security assurances using cryptographic mechanisms. Classic assurances include internet protocols for confidentiality and message integrity — and more recent research includes anonymity assurances.
A simple illustration of public-key cryptography, one of the most widely used forms of encryption. In cryptography, encryption (more specifically, encoding) is the process of transforming information in a way that, ideally, only authorized parties can decode.
The Key Management Interoperability Protocol (KMIP) defines a wire protocol that has similar functionality to the PKCS#11 API. The two standards were originally developed independently but are now both governed by an OASIS technical committee. It is the stated objective of both the PKCS #11 and KMIP committees to align the standards where ...
In cryptography, the Double Ratchet Algorithm (previously referred to as the Axolotl Ratchet [2] [3]) is a key management algorithm that was developed by Trevor Perrin and Moxie Marlinspike in 2013. It can be used as part of a cryptographic protocol to provide end-to-end encryption for instant messaging .
