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 ...
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 protocol is defined for a cyclic group of order with generator . In order to prove knowledge of x = log g y {\displaystyle x=\log _{g}y} , the prover interacts with the verifier as follows: In the first round the prover commits himself to randomness r {\displaystyle r} ; therefore the first message t = g r {\displaystyle t=g^{r}} is ...
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 ...
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.
In cryptography, security (engineering) protocol notation, also known as protocol narrations [1] and Alice & Bob notation, is a way of expressing a protocol of correspondence between entities of a dynamic system, such as a computer network. In the context of a formal model, it allows reasoning about the properties of such a system.
One particular motivating example is the use of commitment schemes in zero-knowledge proofs.Commitments are used in zero-knowledge proofs for two main purposes: first, to allow the prover to participate in "cut and choose" proofs where the verifier will be presented with a choice of what to learn, and the prover will reveal only what corresponds to the verifier's choice.
