Designated Verifier Proxy Re-signature for Deniable and Anonymous Wireless Communications

Journal Article


Abstract


  • In this paper, we introduce a new cryptographic primitive named Designated Verifier Proxy Re-Signature (DVPRS). Different from a normal proxy re-signature, our DVPRS is defined based on the notion of Designated Verifier Signature (DVS) which is very useful in many applications that require “deniable authentication”. Since a DVS can only be verified by a designated verifier, in addition to the re-sign algorithm which allows a proxy to use a resign key to change the signer of a DVS on a message, we also define the re-designate-verifier algorithm for DVPRS which allows a proxy to change the designated verifier of a DVS. We present the formal definition, security model, and an efficient construction of DVPRS, and prove its security under some standard assumptions. We show that DVPRS is very useful in many communication and network applications that require deniable and/or anonymous authentication.
