Chapter 7: The role of cryptography in information security

Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. … Webcryptography noun cryp· tog· ra· phy krip-ˈtä-grə-fē 1 : secret writing 2 : the enciphering and deciphering of messages in secret code or cipher also : the computerized encoding and … green decorations with black background
