Cohen's cryptosystem

Cohen's cryptosystem is a public key cryptographic system based on the mathematical complexity of certain problems in number theory, particularly those related to algebraic geometry and the theory of error-correcting codes. It was proposed by the mathematician Harold Cohen in the early 1980s as a means to provide secure communication. The system uses the structure of certain algebraic curves and the properties of their points to create a key generation and encryption/decryption process.
