This scheme requires a designated verifier that shares the Revocation Authority’s private key. Unlike many accumulator schemes based on bilinear pairings, this scheme is built using a prime-order group and is therefore suitable for system that require standard constructions used in the U-Prove protocol.}, publisher = {Microsoft Research}, url = {http://approjects.co.za/?big=en-us/research/publication/u-prove-designated-verifier-accumulator-revocation-extension-2/}, number = {MSR-TR-2015-40}, }
