00:37:08 | Having discussed symmetric (private) key ciphers during the last two weeks, this week Leo and Steve examine asymmetric key cryptography, commonly known as “Public Key Cryptography”. They begin by examining the first public key cryptosystem, known as the Diffie-Hellman Key Exchange, invented in 1976. Then they describe the operation of general purpose public key cryptosystems such as the one invented by RSA. |
