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 ...
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.
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία-logia, "study", respectively [1]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
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.
Cryptographic primitives are well-established, low-level cryptographic algorithms that are frequently used to build cryptographic protocols for computer security systems. [1] These routines include, but are not limited to, one-way hash functions and encryption functions.
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web.
The cryptography used is Suite A and Suite B, also specified by the NSA as part of the Cryptographic Modernization Program. HAIPE IS is based on IPsec with additional restrictions and enhancements. One of these enhancements includes the ability to encrypt multicast data using a "preplaced key" (see definition in List of cryptographic key types ...
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]
