| dc.description.abstract | With the popularity of cloud computing, how to securely authenticate a user while not releasing a user's sensitive information becomes a challenge. In this paper, we introduce a slight homomorphic signature, which is suitable to implement an access controlling service in cloud computing. In slight homomorphic signature, each user in cloud computing who have a set of identity attributes firstly computes a full signature on all his identity attributes and sends it to a semi-trusted access controlling server. The access controlling server verifies the full signature for all identity attributes. After then, if the user wants to require a cloud service, which may have a special requirement on one of the servers which do not know the secret key can compute a partial signature on this special identity attribute, and then send it to the cloud server for authentication. In the paper, we give a formal secure definition of this slight homomorphic signature, and construct a scheme from Boheh-Boyen signature. We prove that our scheme is secure under a q-SDH problem with a weak adversary. | en_US |
