ABSTRACT:
1. A synchronous binary cryptographic system responsive to an input synchronous telegraph signal comprising means for generating timing pulses of substantially fixed, predetermined frequency, means for generating a synchronous binary cryptographic key in synchronism with timing pulses applied thereto by said means for generating timing pulses, switch means actuated by a predetermined input signal sequence for applying the timing pulses to said means for generating the binary cryptographic key, said cryptographic key generating means being continuously responsive to said timing pulses during operation of the system and means for combining said input signal with the cryptographic key.
