In data communications and information processing systems, cryptography is the most effective way to secure communications and store data. The most commonly used cryptogryphic algorithm is DES (1). However, it is generally implemented with hardware, and the cost is prohibitive for small scale systems such as personal computer communications. Accordingly, an encipherment algorithm that has safety equal to DES and is suitable for software as well as hardware implementation is needed. The FEAL (Fast data Encipherment ALgorihtm) fills this need.
