随着计算机网络的普及,大量的客户数据资料都是聚集和存贮在计算机数据库中,并在用复杂的通讯网连在一起的计算机和终端设备之间进行传输。若没有适当的防护设施,非常容易造成信息的泄露和资料的被窃。公开密钥是相对于私密密钥的密码技术体制的一种,计算机网络安全的维护可以通过端-端加密,链路-链路加密的方式实现,而对于其算法,这里主要介绍安全性能较高的AES-Rijndael算法和较有前景的椭圆曲线密码体制EEC算法。
With the popularity of computer networks, a large amount of customer data is aggregated and stored in a computer database and transmitted between computers and end devices that are connected together using sophisticated communication networks. Without proper protective equipment, it is very easy to cause information leakage and data theft. The public key is a kind of cryptographic system relative to the private key. The maintenance of the computer network security can be realized through end-end encryption and link-link encryption. For the algorithm, the security performance is mainly introduced here High AES-Rijndael algorithm and more promising Elliptic Curve Cryptography EEC algorithm.
