Implementing Pairing-Based Cryptosystems in USB Tokens

Zhaohui Cheng

Abstract

In the last decade, pairing-based cryptography has been the most intensively studied subject in the cryptography field. Various optimization techniques have been developed to speed up the pairing computation. However, implementing a pairing-based cryptosystem in resource constrained devices has been less tried. Moreover, due to progress on solving the discrete logarithm problem (DLP), those implementations are no longer safe to use. In this paper, we report an implementation of a couple of pairing-based cryptosystems at a high security level on a 32-bit microcontroller in a USB token. It shows that USB token supporting secure pairing-based cryptosystems is viable.

Note: More accurate metrics measurement and references added
