Methods and systems for securing information communicated between communication devices
First Claim
1. A method for encrypting information for communication between a first device and a second device, said method comprising:
- generating a random number;
subjecting the random number to a logical XOR component;
transmitting the XOR'"'"'ed random number to a linear-feedback-shift register (LFSR) accumulator; and
providing bits from the LFSR accumulator to a register.

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.
