METHOD AND APPARATUS OF ELLIPTIC CURVE CRYPTOGRAPHY PROCESSING IN SENSOR MOTE AND RECORDING MEDIUM USING IT

摘要

A method of elliptic curve cryptography processing in sensor mote, an apparatus and a recording medium using the same are provided to realize a speedy calculation comparing to a general curve, and implement Koblitz curve in 8-bit Atmega 128 processor. An elliptic curve crypto arithmetic and logic unit produces a first intermediate result value by performing logical multiplication operation in bit component of upper 4 bits of the polynomial of the finite body element and pre-operation table(710). An elliptic curve crypto arithmetic and logic unit produces a second intermediate result value by performing logical multiplication operation of finite field element in the bit component of lower 4 bits of polynomial and pre-operation table(720). An apparatus produces a result value of the finite body multiplication(730).
