cryptography scheme is generally used to set up the second part of the communications, which would use a much faster symmetric-key cryptography scheme, where both parties have the means to ...

An encryption method that uses the same private (secret) key at both ends of the transmission. Contrast with asymmetric cryptography, which uses a public and private key. See secret key cryptography.

This course covers the basic knowledge in understanding and using cryptography. The main focus is on definitions, theoretical foundations, and rigorous proofs of security, with some programming ...

An encryption method for transmitting data that uses key pairs, comprising one private and one public key. Public key cryptography is called "asymmetric encryption" because both keys are not equal.

Encryption can therefore be used either to keep communications secret (defensively) or to identify people involved in communications (offensively). The basic means of encrypting data involves a ...
