Selected Areas in Cryptography 2012, Windsor, Aug. 16-17, Windsor, Canada

Elliptic Technologies' Sr. ASIC Designer/Architect Dr. Jithra Adikari will be giving a talk entitled "Towards Faster and Greener Cryptoprocessor for Eta Pairing on Supersingular Elliptic Curve over F₂1223" at the 2012 Selected Areas in Cryptography Conference (SAC) which will be held in Windsor, Ontario from August 16-17, 2012.

The objective of the SAC conference is to present cutting edge research in areas of cryptography.

The abstract of the talk and associated paper is presented below:

Towards Faster and Greener Cryptoprocessor for Eta Pairing on Supersingular Elliptic Curve over F₂1223
- Jithra Adikari, Anwar Hasan and Christophe Negre

Cryptographic pairing has been used extensively to develop various security protocols, including the well known identity based encryption and the short signature scheme. For such protocols, pairing is by far the most computationally intensive operation. A pairing algorithm typically requires thousands of additions and multiplications followed by a final exponentiation over very large finite fields. From the implementation point of view, pairing is thus very challenging; in fact it is computationally far more demanding than classical cryptographic schemes such as elliptic curve cryptography.

In this paper, we present a new cryptoprocessor for the 128-bit security level eta pairing on a supersingular elliptic curve. The proposed cryptoprocessor is the first known ASIC implementation for eta pairing at the 128-bit security level using binary supersingular curves. This new eta pairing cryptoprocessor is faster and smaller than even the most state-of-the-art eta pairing cryptoprocessors and can be implemented in a highly energy efficient manner.

The presentation is available on Elliptic's Whitepapers page.
