A Generic View on the Unified Zero-Knowledge Protocol and Its Applications

Abstract : We present a generalization of Maurer’s unified zero-knowledge (UZK) protocol, namely a unified generic zero-knowledge (UGZK) construction. We prove the security of our UGZK protocol and discuss special cases. Compared to UZK, the new protocol allows to prove knowledge of a vector of secrets instead of only one secret. We also provide the reader with a hash variant of UGZK and the corresponding security analysis. Last but not least, we extend Cogliani et al.’s lightweight authentication protocol by describing a new distributed unified authentication scheme suitable for wireless sensor networks and, more generally, the Internet of Things.
