摘要:
In stream cipher operation (FIG. 1), a public key cryptographic system employs a filter (21, 22, 31, 32, 33) to alter each sequence (S.sub.i) input to the encryption devices (FIGS. 2 and 3) at the transmitter and the receiver of the system. Characteristics of the filter are known only to the sender and authorized receivers.
