Abstract
In an encryption system comprising DES in a cipher feedback mode of k bits, a plain text bit stream is fed into n individual DES encryptors. The DES encryptor operates in parallel from a common input register containing cipher text bit streams so that the overall throughput of the system is increased approximately by a factor of n. If k=1 then the system is self-synchronizing.
