Concise Vector Commitments and their Applications to Zero-Knowledge Elementary Databases
Zero knowledge sets (ZKS) [18] allow a party to commit to a secret set S and then to, non interactively, produce proofs for statements such as x ∈ S or x /∈ S. As recognized in...

Simulatable VRFs with Applications to Multi-theorem NIZK
Abstract. This paper introduces simulatable verifiable random functions (sVRF). VRFs are similar to pseudorandom functions, except that they are also verifiable: corresponding to...

Multisignatures secure under the discrete logarithm assumption and a generalized forking lemma
Multisignatures allow n signers to produce a short joint signature on a single message. Multisignatures were achieved in the plain model with a non-interactive protocol in groups ...
