Abstract
With the rapid development of the Internet, network technology has gradually penetrated into the lives of ordinary people, and the advent of the era of big data has made people finish work through computers. The development of cloud computing provides people a Virtual platform to solve the computing problems. However, when users outsource data to cloud computing platforms, cloud security issues also come behind. Because cloud computing technology is an emerging technology, technical confidentiality is not enough to meet user needs, and the relevant laws and regulations of the technology are not perfect. It also lacks perfect service agreement management standards and calculation mechanism. To solve the security problems of cloud computing, homomorphic encryption came into being. By analyzing the development trend of cloud computing and the application of homomorphic encryption in cloud computing, this paper introduces the basic knowledge of Paillier encryption algorithm, and proposes a cloud data secure outsourcing protocol, which partially solves the blind computing problems. The method, which transfers the data calculation to the two parties separately through key division, can ensure the security of the data in the calculation and protect the integrity and confidentiality of the outsourced data in the entire process. Through protocol analysis, this method can achieve the expected result.
