A Mobile Data Leakage Prevention System Based on Encryption Algorithms

Mobile Internet is an emerging field that is developing rapidly. However, the frequent data leakage events caused by the security problems of mobile Internet have brought great impact to enterprises and individuals. Cryptography is promising way for data security and is widely used in the industries such as power systems. How to effectively use data encryption algorithms in the field of mobile Internet to meet the security requirements of data sharing is a problem to be solved. Therefore, this paper proposes a mobile data leakage prevention system that adopts the encryption algorithms SM3 and SM4 that are approved by the State Cryptography Administration of China. The cipher-text retrieval model is proposed for secure data sharing between data owner and data user via cloud servers. The system model that is built based on the studied encryption algorithms and models is describe. Additional functions are also designed for mobile data leakage prevention such as data security management and security data analysis. The proposed system is expected protect the data transmission, storage and sharing between data owner, data user and cloud server, providing an architecture to build a security mechanism to lower the risks from data theft, eavesdropping and tampering.
