Pfitzmann, Birgit (ed.), Advances in cryptology - EUROCRYPT 2001. 20th international conference on theory and application of cryptographic techniques, Innsbruck, Austria, May 6-10, 2001. Proceedings. Berlin: Springer. Lect. Notes Comput. Sci. 2045, 495-511 (2001).
Summary: We provide identification protocols that are secure even when the adversary can reset the internal state and/or randomization source of the user identifying itself, and when executed in an asynchronous environment like the Internet that gives the adversary concurrent access to instances of the user. These protocols are suitable for use by devices (like smartcards) which when under adversary control may not be able to reliably maintain their internal state between invocations.
