WebMay 21, 2024 · Public key cryptosystem is one which involves two separate keys for encryption and decryption. Each user participating in the communication has to generate two keys, one is to be kept secret (private key) and one is to make public (public key). Public key cryptosystem can achieve both confidentiality and authenticity. 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.
