WebA cryptosystem supports secure communication by deploying algorithms to establish a shared secret value, known as a “key,” used for encryption and decryption purposes. A cryptosystem also allows communicating entities to verify one another’s identity via a “digital signature.”. A digital signature authenticates a user through the use ... Web•Public key encryption SLOWER than symmetric ==> Hybrid •1. Random secret key (“session key”; discard when done) •2. Encrypt message w/ session key & symmetric alg. •Encrypt session key w/ recipient’s public key (==> “digital envelope”) •Send encrypted message + digital envelope.
