This paper focuses on the problem of data security in the special environment of cloud, and mainly makes the following two aspects:

1. For security issues such as protecting the privacy of user inquiries and data confidentiality, by analyzing the advantages and disadvantages of existing schemes, combining cryptography theory, an improved scheme is proposed for a data retrieval scheme based on all-homomorphic encryption, which can not only guarantee the user's data not to be leaked, but also ensure the privacy of the user's query process.

2. In the protection of user data integrity, the traditional Mac authentication method is not adopted, and a data integrity test scheme based on RSA is improved. It combines the PDP model and the third party audit, not only the customer can verify the integrity of the data, but also authorize the trusted third party to authenticate it.
