Abstract: Big data has brought new development opportunities to the communication industry and also brought a lot of safety problems such as it could easily produce the background system security protection level lags behind the business development situation. In this paper, we propose a new static and decryption strategy for sensitive data in the large data platform, aiming at the new technical features of big data and the application of business new forms. Based on symmetry of AES encryption algorithm optimization to realize the dual mode static desensitization of the original data, make sure to privacy will not affect the system performance, and to achieve dynamically invoke a particular algorithm decryption according to particular demand and meet different business scenarios. It makes the enterprise big data front and backstage are all secure and private which protects the inside part while plays the greater value in the external.
