WebIn cryptography, a round or round function is a basic transformation that is repeated multiple times inside the algorithm.Splitting a large algorithmic function into rounds simplifies both implementation and cryptanalysis.. For example, encryption using an oversimplified three-round cipher can be written as = ((())), where C is the ciphertext and P is the plaintext. WebApr 7, 2024 · Quantum cryptography is a "method of encryption that uses the naturally occurring properties of quantum mechanics to secure and transmit data in a way that cannot be hacked," according to TechTarget.
