Making the most of noise
The goal of secure identification is to enable a user, Alice, to identify herself to Bob without revealing her password. Unfortunately, like many other interesting cryptographic problems involving two parties, this is impossible to achieve without making assumptions. For example, we could assume that factoring a large number is difficult. However it is not known whether this assumption is correct.
