Transformation of 1-out-of-n Oblivious Transfer and Its Application
Lizhen Ma · Dianzi Ke-ji Daxue xuebao · 2008
A new application to group signature on 1-out-of-n oblivious transfer is proposed. After introducing,the transformation of 1-out-of-n oblivious transfer protocol proposed by Ref.[1],a new membership revocation method in group signature is proposed by use of the transformation protocol. The proposed method is a universal method and can be applied to any group signature scheme;however,the previous revocation methods are only applicable to a specific group signature scheme. Under the random oracle model and computational Diffie-Hellman(CDH) assumption,the proposed protocol is provably secure.
