Abstract(in Japanese) (See Japanese page)
Abstract(in English) In a setting that a single user is given plural credentials on her attributes and related secret keys, an authentication method to the user should be capable of simultaneously authenticate the plural credentials. Also, from the view point of users' privacy increasing recent years, there arises a need for such an attribute-authentication scheme with anonymity of users' identities. On the other hand, in the anonymous attribute-authentication scheme, a collusion attack is typical, where an adversary collects credentials on of attributes from plural users and tries to make a verifier accept. In this report, we propose an anonymous attribute-authentication scheme with collusion resistance in the setting of plural authorities on key generation. The anonymity is achieved by identity-indistinguishable property.
