The Blum–Micali algorithm is a cryptographically secure pseudorandom number generator. The algorithm gets its security from the difficulty of computing discrete logarithms. Let be an odd prime, and let be a primitive root modulo . Let be a seed, and let . The th output of the algorithm is 1 if . Otherwise the output is 0. This is equivalent to using one bit of as your random number. It has been shown that bits of can be used if solving the discrete log problem is infeasible even for exponents with as few as bits.

  • The Blum–Micali algorithm is a cryptographically secure pseudorandom number generator. The algorithm gets its security from the difficulty of computing discrete logarithms. Let be an odd prime, and let be a primitive root modulo . Let be a seed, and let . The th output of the algorithm is 1 if . Otherwise the output is 0. This is equivalent to using one bit of as your random number. It has been shown that bits of can be used if solving the discrete log problem is infeasible even for exponents with as few as bits. In order for this generator to be secure, the prime number needs to be large enough so that computing discrete logarithms modulo is infeasible. To be more precise, any method that predicts the numbers generated will lead to an algorithm that solves the discrete logarithm problem for that prime. There is a paper discussing possible examples of the quantum permanent compromise attack to the Blum–Micali construction. This attacks illustrate how a previous attack to the Blum–Micali generator can be extended to the whole Blum–Micali construction, including the Blum Blum Shub and Kaliski generators. (en)
