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 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 .
The task of the authentication protocol is to specify the exact series of steps needed for execution of the authentication. It has to comply with the main protocol principles: A Protocol has to involve two or more parties and everyone involved in the protocol must know the protocol in advance. All the included parties have to follow the protocol.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
In cryptography, a zero-knowledge proof is a protocol in which one party (the prover) can convince another party (the verifier) that some given statement is true, without conveying to the verifier any information beyond the mere fact of that statement's truth. [1]
The WireGuard protocol is a variant of the Noise Protocol Framework IK handshake pattern, as illustrated by the choice of Noise_IKpsk2_25519_ChaChaPoly_BLAKE2s for the value of the Construction string listed on p10 of the Whitepaper. WireGuard uses the following: [8] Curve25519 for key exchange; ChaCha20 for symmetric encryption
QUIC has been specifically designed to be deployable and evolvable and to have anti-ossification properties; [30] it is the first IETF transport protocol to deliberately minimise its wire image for these ends. [31] Beyond encrypted headers, it is 'greased' [32] and it has protocol invariants explicitly specified. [33]
Cap'n Proto protocol is theoretically suitable [9] for very fast inter-process communication (IPC) via immutable shared memory, but as of October 2020 none of the implementations support data passing via shared memory. [10] However, Cap'n Proto is still generally considered faster than Protocol Buffers and similar RPC libraries. [11] [12]
