DOIAbstract
In this paper a new signature scheme, called Policy-Endorsing Attribute-Based Signature, is developed to correspond with the existing Ciphertext-Policy Attribute-Based Encryption This signature provides a policy-and-endorsement mechanism In this mechanism a single user, whose attributes satisfy the predicate, endorses the message This signature allows the signer to announce his endorsement using an access policy without having to reveal the identity of the signer The security of this signature, selfless anonymity and existential unforgeability, is based on the Strong Diffie-Hellman assumption and the Decision Linear assumption in bilinear map groupshttp://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=...
