Universal designated verifier signature (proof) schemes without random oracles
|
Abstract:
Based on the latest proposed k+1 assumption, two different schemes of universal designated verifier signature were proposed. Both of them are provably secure without random oracles. The second scheme, in which the holder can designate his/her signature to anyone he/she wants and an efficient interactive protocol is used to verify the designated signature, is usually called universal designated verifier signature proof scheme.
