Tiny Encryption Algorithm
Apparence
Tiny Encryption Algorithm (TEA) is a block cipher notable for its simplicity of description and implementation (typically a few lines of code). It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory, and first presented at the Fast Software Encryption workshop in 1994 (Wheeler and Needham, 1994). It is not subject to any patents. Vikram Reddy Andem, presented a comprehensive study of TEA and cryptanalysis of the TEA (see below).
