摘要
A method and device for protecting elliptic curve cryptography against simple power attacks is disclosed. The method is based on a processor such as a computer equipped to encrypt and decrypt communications and selecting and entering a point P on an elliptic curve in the computer. The processor provides k copies of the point P (kP). The processor is used to divide a string of Ks into two equal length partitions that are scanned from right to left and performing point doubling operation and delay the point addition operation by storing the some doubled points in a buffer for later performing of addition operation.
