@inproceedings{Okamoto1992ProvablySA, title={Provably Secure and Practical Identification Schemes and Corresponding Signature Schemes}, author={Tatsuaki Okamoto}, booktitle={CRYPTO}, year={1992} }

This paper presents a three-move interactive identification scheme and proves it to be as secure as the discrete logarithm problem. This provably secure scheme is almost as efficient as the Schnorr identification scheme, while the Schnorr scheme is not provably secure. This paper also presents another practical identification scheme which is proven to be as secure as the factoring problem and is almost as efficient as the Guillou-Quisquater identification scheme: the Guillou-Quisquater scheme… Expand
