Explain primality testing in cryptography
WebDec 3, 2024 · The setup of an RSA cryptosystem involves the generation of two large primes, say p and q, from which, the RSA modulus is calculated as n = p * q. The greater the modulus size, the higher is the security level of the RSA system. The recommended RSA modulus size for most settings is 2048 bits to 4096 bits. Thus, the primes to be … WebApr 12, 2024 · Randomized algorithms have huge applications in Cryptography. Load Balancing.
