In this paper, a new and efficient algorithm for searching public key Cryptography (Nscf-peck) is proposed. This scheme is based on bilinear pair structure and uses public channel to transmit ciphertext. In the design of the whole algorithm, only two times bilinear pair operation is used, which greatly reduces the computational expenditure of the searchable public key cryptography. Meanwhile, using public channel to transmit encrypted data between client and cloud server reduces the cost of constructing secure channel. Finally, this paper proves the consistency of the Nscf-peck scheme, and deeply analyzes the efficiency and security of the algorithm. Based on the above Nscf-peck searchable public key encryption scheme, this paper proposes an application scheme of cloud cipher search system. This application scheme uses MapReduce Parallel computing model technology to design the parallel search engine of the application scheme, applies some open source technology and distributed computing idea to the application scheme, and improves the search efficiency of the massive ciphertext by taking full advantage of cloud computing technology. The system adopts layered and modular design ideas to ensure the maintainability, scalability and flexibility of the application.
