Design and implementation of cloud storage system based on Homomorphic encryption

Beijing posts and telecommunications Song Dan 劼希

When the encrypted data stored on the cloud server is developed to a certain scale, the effective retrieval of encrypted data will be an urgent problem, the traditional information retrieval technology has been difficult to meet the needs of the massive data retrieval in cloud storage environment, and the effective retrieval of cloud encryption data has become one of the important research topics to be solved urgently.

In the case of data encryption, the Homomorphic encryption scheme can be used to statistic, analyze and retrieve the ciphertext information, and the result of operation is automatically encrypted. Therefore, in order to balance security and the need to serve cloud computing, we introduced the concept of homomorphic cryptography. By studying the latest Homomorphic encryption scheme in foreign countries, we design an improved algorithm, which is more suitable for ciphertext retrieval under the current cloud computing environment, and solves the security problems brought by the original algorithm by searching.

In this thesis, we design the experiment platform of cloud storage system based on client/server model, and complete the requirement analysis, framework design, function module design, frame building, system development, system testing and so on.
