AbstractAs cloud computing has become an incredibly important task in real life, security of privacy in many areas, in especially in the context of Personal Health Record (PHR), has indeed been given growing attention. The traditional encryption based on ciphertext policy (CP-ABE) allows you to control the scrambled PHR information policy in a fine-grained manner, however the accessing policy is also sent with the cipher text. The entry policy, however, cannot activate the anonymity of users, as it includes an excessively large number of confidential information from valid users of software. It is now important to ensure the privacy of users through hiding access strategies. The overwhelming majority of previous plans however have to deal with two problems: (1) certain plans do not accept a wide universe of the attributes, hence their common sense in PHR is considerably reduced and (2) the decryption costs are very high because the entry scheme is set up in cypher text. Their utility is thus drastically limited. To resolve these problems, we create a CP-ABE plot with proficient decryption, where both the scale of available parameters and the cost of decryption are steady. In addition, by using the dual system encoding technique, we demonstrate that the proposed conspire achieves full safety in the standard model.
