Cryptography Questions
A key agreement key is a cryptographic key that is generated and shared between two or more parties to establish a secure communication channel. It is used in key agreement protocols, such as Diffie-Hellman, to enable the parties to agree upon a shared secret key without revealing it to any eavesdroppers. The key agreement key is typically derived from the exchanged public keys and other parameters, and it is used to derive the actual encryption and decryption keys for secure communication.
