The Research Of Security Technology On Cloud Storage

With the expansion of the scale of data storage, cloud storage technology with its characteristics of high performance and low cost has been gotten a lot of attention and support. But due to its own issues of data’s security, cloud storage can’t get further promotion. This paper focuses on the analysis of two aspects of cloud storage security, both security authentication and data encryption storage.In view of the present low efficiency of cloud storage security authentication, this paper proposes a mechanism of identity-based security authentication, the mechanism for the user’s unique identifier as the public key, with the features of a small key size, free certificates, fewer communication interaction, so the efficiency of the authentication has been greatly improved.Aiming at the application of static data encryption storage in the cloud storage, this paper proposes a new set of cloud storage encryption and storage solution at the side of the server of cloud storage, based on the key separation and encryption strategy. This scheme by using a new method to manage the key and encryption, finally achieves the guarantee of higher security of data storage from the technical level.
