Résumé :

In this paper, we describe two serious weaknesses of an identitybased identification scheme proposed by Girault (presented at Eurocrypt '90) that enables adversaries to forge identity, key pairs for a large group of users. We also show how to modify the scheme to make the attacks ineffective.
