%X For defensing side-channel attacks about elliptic curve cryptosystem and in view of SCA on elliptic curve cryptosystem mainly concentrated on scalar operation, this paper proposed RWNAF refined Width-w NAF and FWNAF fractional Width-w NAF with pre-computed table, which was intends to resist SPA, DPA, RPA and ZPA essentially. It utilized Masking technology to thwart those attacks, meanwhile it optimized pre-computed table by the characteristic of the even and odd scalar. Further FWNAF utilized the fragments window technology, improving utilization ratio of the storage resource, also reducing system computing performance "jitter" by the system resources sharp change caused.
