Data encryption technology for coal mine safety monitoring and control system

For data encryption storage requirement of safety monitoring and control system in Technology schemes of upgrading of coal mine safety monitoring and control system(exposure draft), database encryption technology was researched, and performances of four data encryption algorithms including DES, RSA, homomorphism and binary serialization were tested and compared. A data encryption scheme suitable for coal mine safety monitoring and control system was proposed, which used different data encryption algorithm for different field type. The scheme realizes safe and quick data encryption storage for coal mine safety monitoring and control system.
