The process begins by having the two parties, alice and bob. [1][2][3] this shared secret may be directly used as a key, or to derive another key. Elgamal encryption is performed in three phases The key generation, the encryption, and the decryption The first is purely key exchange, whereas the latter two mix key exchange computations with message computations. Diffie and hellman's 1976 paper new directions in cryptography[5] introduced a radically new method of distributing cryptographic keys, that helped solve key distribution —a fundamental.
[1] the cdh assumption involves the problem of computing the discrete logarithm in cyclic groups Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm After obtaining an authentic copy of each other's public keys, alice and bob can compute a shared.
