Efficient subgroup exponentiation in quadratic and sixth degree extensions
2002
Cryptographic Hardware and Embedded Systems - CHES 2002. 4th International Workshop Revised Papers
This paper describes several speedups for computation in the order p + 1 subgroup of F*(p<sup>2</sup>) and the order p<sup>2</sup> - p + 1 subgroup of F*(p<sup>6</sup>). These results are in a way complementary to LUC and XTR, where computations in these groups are sped up using trace maps. As a side result, we present an efficient method for XTR with p ≡ 3 mod 4
