anonymous appra isal mult-i signaturew ith messagemodifiable group signature b ilinearm aps
Based on bilinearmaps, a scheme o fmu lt-i signature w ithmessagemodifiable is constructed. This paper proposes an anonymous appraisal protoco l using themult-i signature and group signature. The security ana lysis of the protocol show s that it has a good anonym ity and capab ility of coal-i t ion-resistance. The protoco l can be app lied to m any fields such as e lectronic commerce and electron ic government.
