ABSTRACT:
A system is provided for generating information for secure transmission from a first device to a second device. The system comprising a key scheduler for generating a dynamic secret key, a synchronization generator for generating a synchronization sequence and controlling the frequency of the dynamic secret key, a padding generator for generating a padding sequence, and a DEK generator for generating encrypted text. The system generating a stream of encrypted information that includes the synchronization sequence prior to and adjacent the encrypted text which is prior to and adjacent the padding sequence.
