Elliptic curve cryptosystem (ECC) has high security and calculation efficiency. Energy attack is a powerful crypto attack method, which attacks the chip cryptography algorithm by using the information leaked by the crypto chip during its operation. Aiming at the situation that the side channel attacks of ECC mainly focus on scalar multiplication, The FWNAF is proposed. It uses the fragment window technology to improve the use ratio for storage resources, reduce the “jitter” caused by rapid change of system resources.
