Efficient Pairing Computation on Huff Curves.

Pairings on elliptic curves are currently of great interest due to their applications in a number of cryptographic protocols such as identity-based encryption, group signatures, short signatures, and the tripartite Diffie-Hellman. Miller's algorithm is the most commonly used method of computing Tate pairing. Denominator elimination can improve Miller's algorithm when the embedding degree has the form 2i3j. However, if the embedding degree does not have the above form, how can the speed of Miller's algorithm be increased? In this article, the authors modified Miller's algorithm over Huff curves. It is about 20.38% faster than the original algorithm. [ABSTRACT FROM PUBLISHER]
