Schnorr’s identification and signature schemes [10], [11] are efficient, discrete log-based protocols. Moreover, preprocessing algorithms are proposed that significantly speed up the computations of the prover (resp. signer). Therefore, this preprocessing greatly enhances the suitability for implementation on a smart card. The preprocessing algorithms can(More)
