In this paper the authors present an efficient and side channel protected software implementation of point multiplication for the standard NIST and SECG binary elliptic curves. The enhanced performance is achieved by improving the Lopez-Dahab/Montgomery method at the algorithmic level, and by leveraging Intel's AVX architecture and the pclmulqdq processor instruction at the coding level. The fast carry-less multiplication is further used to speed up the reduction on the newest Haswell platforms. For the five NIST curves over GF(2m) with m (163; 233; 283; 409; 571), the resulting point multiplication implementation is about 6 to 12 times faster than that of OpenSSL-1.0.1e, enhancing the ECDHE and ECDSA algorithms significantly.
