METHOD FOR ELLIPTIC CURVE PUBLIC KEY CRYPTOGRAPHIC VALIDATION

摘要

Communication and validation of information transmission from the realization of transmitted from transmitter to receiver be by generate password (400) from the parameter of the elliptic curve that message (410) utilizes, generator (406) elliptic curve on point P public key Q (416) receiver. Random number k (404) of the password comprising first unit product kP and generation point P and second element, the i.e. product of the x coordinate of product m and product kQ. Two kinds of arithmetic of message m from information it is independent expression and, optionally, random number. Password is transmitted to receiver, and recycles message m ' (502). Verifying token (500) is to be generated by receiver and passed through transmitter, if this verification information is communicated to receiver product mkQ equal to the confirmation flag.
