SEVIL: secure and efficient verifIcation over massive proofs of knowLedge

Abstract

This paper presents SEVIL, a group signature construction that offers an efficient, aggregated and batch ver- ification over multiple signatures. The proposed group signature scheme is built upon Groth-Sahai Non- Interactive Witness-Indistinguishable proofs, in an effort to reduce the computation complexity, closely as- sociated with the number the number of signatures. SEVIL fulfills the main security and privacy properties, proven through a detailed analysis. The implementation of SEVIL algorithms demonstrates the high efficiency of the aggregated and batch verification with up to 50% of gain in comparison with naive verification of NIWI proofs.
