Fuzzy Identity-Based Identification Scheme
We present a new type of Identity-Based Identification (IBI), namely Fuzzy Identity-Based Identification (FIBI). FIBI is an extension of traditional IBI where the identity (ID) is viewed as a set of values. In FI...

A new approach for UC security concurrent deniable authentication
Deniable authentication protocols allow a sender to authenticate a message for a receiver, in a way which the receiver cannot convince a third party that such authentication ever took place. When we consider a...
