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 ...
The symbolic nature of the Dolev–Yao model makes it more manageable than computational models and accessible to algebraic methods but potentially less realistic. However, both kinds of models for cryptographic protocols have been related. [5]
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.
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]
The following outline is provided as an overview of and topical guide to cryptography: Cryptography (or cryptology) – practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic ...
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 ...
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 ...
The Signal Protocol (formerly known as the TextSecure Protocol) is a non-federated cryptographic protocol that provides end-to-end encryption for voice and instant messaging conversations. [2] The protocol was developed by Open Whisper Systems in 2013 [ 2 ] and was introduced in the open-source TextSecure app, which later became Signal .
