Continous cipher synchronization for cellular communication system.
Abstract
In digital cellular system encryption device synchronous system. The encryption device and generating comprises more than counters with the processing pseudo-random key flow of enciphered data combination. The current is a counter values functions according to respond the sequence clock pulse periodicity gain progressively. A enciphered a data, wherein a system capable of providing mode counter value correctly continuously or very frequent rotating, wherein the transmitter counter can be used for receiving the inverse driving and system is synchronize no need to restarting or and clock pulse repeatedly.
