A Note on Girault's Self-Certified Model

Shahrokh Saeednia

Abstract

In this paper, we describe an important shortcoming of the first self-certified model proposed by Girault, that may be exploited by the authority to compute users' secret keys. We also show, while it is possible to make the attack ineffective by taking additional precautions, the resulting model loses all merits of the original model and does no longer meet the primary contribution of the self-certified notion.
