Public-key encryption (PKE) is an elegant solution to the fundamental problem of cryptography – secure communication between two parties over a public (insecure) channel. The basic idea is that every user A holds two keys – a public key (PKA) and a secret key (SKA). A user who wants to send a message to A encrypts it with PKA and sends the resulting ciphertext along the public channel. A, at the other end of the channel, decrypts the ciphertext using SKA and obtains the message. SKA is known to user A alone. Any third party intercepting data on the public …
