Cryptographic protocols essay
As a result, the aim of this special issue is to highlight the latest technologies and solutions that focus on theory, analysis, experimentation or application of cybersecurity, cryptography. Cryptography is the practice and study of techniques for secure communication in the presence of third parties. It is also used to establish a secure connection between two systems. Cryptography uses mathematics, primarily arithmetic and number theory, to provide confidentiality, integrity and authenticity for messages under certain circumstances. Elliptic curve cryptography is an important class of algorithms. Elliptic Curve Diffie-Hellman, often simply referred to as ECDH, is a key exchange or key agreement protocol used to establish a shared secret over an insecure medium. That shared secret is then used directly or as a basis to derive another key. A cryptographic protocol is a distributed protocol. algorithm that precisely describes the interactions of two or more entities to achieve certain security objectives over a public-private network. Cryptographic protocols are designed using cryptographic primitives such as encryption, hashing, signing, threshold cryptography, links,
