Encryption Technology for Computer Network Data Security Protection

In order to solve the network security problem of data encryption technology, this paper proposes a research method computer information maintenance based on technology. Taking reporting system mining enterprise as object, comprehensively expounds design and in communication from aspects demand investigation, analysis, design, software development, so implements development by using BS architecture + independent client. The experimental results show that AES algorithm can be independently designated 128 bits, 192 256 bits. Conclusion. This scheme realize rapid safe transmission provide an effective means for confidential documents network, it has good application prospect.
