This technique was also used in Babylon and Asyria. In the Bible, a Hebrew ciphering method is used at times. In this method, the last letter of the alphabet is replaced by the first, and vice versa. This is called 'atbash'. WebDiffie and Hellman (1976) introduced the concept of public key encryption, also known as asymmetric cryptography in 1976.
