Patent ID: 7688976

Claim:
A system of encryption for communication security that uses an encryption algorithm and a pre-placed encryption key, the system comprising: a. a random wave generator function generates a random wave envelope by additively combining periodic waves of types of, a triangle, a square and a sine functions and that yields a random number from a y-axis amplitude value of the random wave envelope for an x-axis value; b. a jitter security function by operation of the random number with the pre-placed key at time of encryption generates a random-variant-key in a temporary memory of an encryption device; and c. a security function uses the random-variant-key for encryption of a data block and immediately thereafter discards the random-variant-key, then uses the jitter function to generate a next random variant key for the encryption of a next data block and also immediately discards the next random variant key, thereby the encryption device stores only the pre-placed key.
