WebApr 12, 2024 · The McEliece cryptosystem, introduced by Robert J. McEliece in 1978, was the first code-based public-key cryptosystem and the first to use randomization in the encryption process. It's a one-way system, which means that cyberattackers can't easily find a randomly chosen code word using a ciphertext and public key. WebThe basic intention of an attacker is to break a cryptosystem and to find the plaintext from the ciphertext. To obtain the plaintext, the attacker only needs to find out the secret decryption key, as the algorithm is already in public domain. Hence, he applies maximum effort towards finding out the secret key used in the cryptosystem.
