With the approach of the big data era, the risks and problems of information data security influence people’s life and even public security seriously. To relieve these issues, integrative security protection system for full life cycle of big data is proposed, of which SM Crypto Algorithm is introduced for data security protection of all phases in data life cycle, including data collection, data transmission, data storage, data exchange and sharing, and data destruction. Relying on the safety performance of SM2 (the public key cryptographic algorithm based on elliptic curves) and SM4 (the block cipher algorithm), the protection mechanism ensures the security of the identity access control and encryption of data transmission, storage, exchange and application.
