A New Human Identification Protocol and Coppersmiths Baby-Step Giant-Step Algorithm

摘要：

We propose a new protocol providing cryptographically secure authentication to unaided humans against passive adversaries. We also propose a new generic passive attack on human identification protocols. The attack is an application of Coppersmiths baby-step giant step algorithm on human identification protcols. Under this attack, the achievable security of some of the best candidates for human identifi cation protocols in the literature is further reduced. We show that our protocol preserves similar usability while achieves better security than these protocols. A comprehensive security analysis is provided which sug gests parameters guaranteeing desired levels of security.
