Abstract
An encryption apparatus and method for generating a ciphertext from an input plaintext of the same length as the ciphertext by parallel processing of the input signal. Since a non-delayed signal is synchronized to a delayed signal, an accurate ciphertext is produced. Therefore, the encryption speed is increased, the number of devices for timing synchronization is reduced, an encryption system is stabilized, and production cost is reduced.
