ABSTRACT:
A simple encryption and decryption device has been developed. The underlying algorithm is a fast block cipher that may be implemented efficiently in hardware or software. The algorithm makes heavy use of data-dependent rotations. The amount of each rotation depends on the data being encrypted and intermediate encryption results. The variables for the algorithm include word size, rounds, and the length of a secret key.
