Side Channel Attacks against Pairing over Theta Functions

Nadia El Mrabet

Abstract: In \cite{LuRo2010}, Lubicz and Robert generalized the Tate pairing over any abelian variety and more precisely over Theta functions. The security of the new algorithms is an important issue for the use of practical cryptography. Side channel attacks are powerful attacks, using the leakage of information to reveal sensitive data. The pairings over elliptic curves were sensitive to side channel attacks. In this article, we study the weaknesses of the Tate pairing over Theta functions when submitted to side channel attacks.

Category / Keywords: public-key cryptography / pairing based cryptography, Theta function, side channel attacks, differential power analysis, fault attacks.

Publication Info: Long version of the article to be published in the proceedings of the CAI 2013 conference.
