Data Safety Research On Management Information Systems Of E-Commerce

China electronic commerce is apid development, it is expected that in 2010 amounted to 10 trillion market transactions in China. With the popularity of e-commerce, the security problem is getting attention. E-commerce security is a core development constraints and key issues, development of efficient e-commerce security management system is very necessary.The paper analysis the safety of domestic and international e-commerce research, according to E-Commerce security architecture, analysis the risk and research the security technology of levels:network service layer, layer encryption, security certification level, the transaction protocol layer, business systems layer. Focus on the implementation of encryption layer solutions presented the corresponding, Design and implement a secure data encryption transmission system. Encrypted data for security and data transfer performance issues, using appropriate encryption algorithm improves system security and speed.MD5 authentication for the identity of the data transfer performance issues, this article through data encryption algorithms DES,RSA were analyzed and compared, integrated set up a secure data transmission system design and implementation of information exchange formats, exchange protocol and processing decryption algorithm,thus ensuring the security of data transmission.
