Asymmetric encryption.

Download chapter PDF. Another name for asymmetric encryption is public-key cryptography (PKC).

Types of encryption: Asymmetric Encryption . James Ellis, a British mathematician, came up with the idea of asymmetric cryptography, i.e., using two separate keys for encryption and decryption. In this scenario, the receiver of the message is actively involved in the process as well, instead of just being a passive passenger.Public key cryptography is a method of encrypting or signing data with two different keys and making one of the keys, the public key, available for anyone to use. The other key is known as the private key. Data encrypted with the public key can only be decrypted with the private key. Because of this use of two keys instead of one, public key ...
