WebOct 22, 2024 · Post-quantum cryptography is the study of cryptosystems which can be run on a classical computer, but are secure even if an adversary possesses a quantum computer. Recently, NIST initiated a process for standardizing post-quantum cryptography and is currently reviewing first-round submissions. In cryptography, a cryptosystem is a suite of cryptographic algorithms needed to implement a particular security service, such as confidentiality (encryption). Typically, a cryptosystem consists of three algorithms: one for key generation, one for encryption, and one for decryption.
