On non-delegatability property of strong designated verifier signature

Journal Article


Abstract


  • Aimed to the attack on delegatability for designated verifier signature (DVS) and the property of weak non-delegatability for strong designated verifier signature (SDVS), a notion of strong privacy of signer's identity for SDVS was proposed, which is the privacy of signer's identity under the delegatability notion. Then it was shown that there exists the scheme which satisfies this property. Finally this notion was verified to be consistent with the notion of common key delegation and the concept of SDVS. Unlike the previous definition of weak non-delegatability, this notion is applicable to both DVS and SDVS schemes, which means that weak non-delegatability is redundant.
