WebPublic-key cryptography refers to a class of cryptographic systems in which each actor uses two keys: a public key that is known to all, and a corresponding private key that is known only to the actor. The guiding principle is that messages intended for a specific person should be encrypted using their public key in such a way that the message can … Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. Security of public-key cryptography depends on keeping the private …
