- Abstract
At present, most searchable encryption focuses on text search, aiming at how to search graphics in cloud computing, a new privacy preserving searchable encryption scheme under public key system is proposed. Through a new similarity judgment technique, the characteristic information of graphic shape is transformed into single keyword encryption, and the graphic shape searchable encryption (GSSE) is realized by using the public key authentication encryption with keyword searchable (PAEKS), which realizes the function of protecting the privacy of users and data, and the fixed size ciphertext and trapdoor are achieved. Finally, under the random oracle model, it is proved that the scheme proposed in this paper has the semantic security of external selection multi-keyword attack and internal keyword guessing attack. Finally, under the random oracle model, the semantic security of external selection multi- keyword attack and internal keyword guessing attack of the scheme is proved. The experimental results show that the scheme has high efficiency.
