Abstract

Abstract

In order to protect the privacy of ${\rm{users}}' $ personal information and friend preferences in social networks, a Ciphertext-Policy Attribute Based Encryption (CP-ABE) scheme that supports outsourced decryption is proposed. In this scheme, attribute lists are generated for the ${\rm{users}}' $ dating preference and self-description respectively, and attributes are hidden by converting the dating preference into ciphertext control policy and self-description into attribute key, thus realizing privacy protection. The proposed algorithm mechanism matches ${\rm{users}}' $ information and then decrypts it. ${\rm{Users}}' $ information is matched and verified by social platform. When the corresponding matching conditions are met, the algorithm outsources the computationally expensive bilinear pairing operation to the dating center. The user then decrypts the ciphertext. Invalid decryption is avoided by quickly eliminating mismatched users. Outsourced decryption reduces the computational burden and communication overhead of mobile devices while protecting information. Security analysis shows that the scheme is safe and effective, furthermore, performance evaluation shows that the proposed scheme is efficient and practical in terms of computational and communication overhead.
