Rabin Cryptosystem is an public-key cryptosystem invented by Michael Rabin. It uses asymmetric key encryption for communicating between two parties and encrypting the message. The security of Rabin cryptosystem is related to the difficulty of factorization. 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. fish and chips howth
