SPA-RESISTANT LEFT-TO-RIGHT RECODING AND UNIFIED SCALAR MULTIPLICATION METHODS |
摘要 |
Provided is a scalar multiplication method unified with a simple power analysis (SPA) resistant left-to-right recording in a crypto system based on an elliptic curve and a pairing. The scalar multiplication method includes: recording an L-digit secret key k′ from a radix-r n-digit secret key k by comparing two successive elements with each other from the most significant digit with duplication allowed in order to generate the L-digit secret key k′; and performing scalar multiplication between the secret key k and a point P on an elliptic curve to output a scalar multiplication value Q=kP using the secret key k′.
