An epistemic characterization of zero knowledge
Halpern, Moses and Tuttle presented a definition of interactive proofs using a notion they called practical knowledge, but left open the question of finding an epistemic formula...

Zero knowledge with efficient provers
We prove that every problem in NP that has a zero-knowledge proof also has a zero-knowledge proof where the prover can be implemented in probabilistic polynomial time given an NP ...

Square Complex Orthogonal Designs with Low PAPR and Signaling Complexity
Abstract--Space-Time Block Codes from square complex orthogonal designs (SCOD) have been extensively studied and most of the existing SCODs contain large number of zero. The zeros ...

Unifying Zero-Knowledge Proofs of Knowledge
Abstract. We present a simple zero-knowledge proof of knowledge protocol of which many protocols in the literature are instantiations. These include Schnorr’s protocol for provin...
