The Goldwasser–Micali (GM) cryptosystem is an asymmetric key encryption algorithm developed by Shafi Goldwasser and Silvio Micali in 1982. GM has the distinction of being the first probabilistic public-key encryption scheme which is provably secure under standard cryptographic assumptions. … See more The GM cryptosystem is semantically secure based on the assumed intractability of the quadratic residuosity problem modulo a composite N = pq where p, q are large primes. This assumption states that given (x, N) it is difficult to … See more Goldwasser–Micali consists of three algorithms: a probabilistic key generation algorithm which produces a public and a private key, a probabilistic encryption algorithm, and a … See more • Blum–Goldwasser cryptosystem See more Web2012: Silvio Micali (1983) 和 Shafi Goldwasser (1984) 2015: Martin Hellman 和 Whitfield Diffie; 最近的两位的工作更偏向于 crypto, 所以重点放在前三位吧.
