随着科技的发展，网络已经成为人们生活中不可或缺的一部分。与此同时，对网络信息的保护也变得越来越重要。加密是保护信息最有效的方法之一。发送方对数据进行对称加密并通过网络发送，接收方对信息进行解密得到明文。网络上的所有信息都被加密了。对称密钥将通过非对称密钥得到最有效的分布。RSA算法和ECC算法是最重要的两种非对称算法。SM2算法由国家密码管理局自主开发；对国际标准的ECC算法进行了改进和扩展。介绍了认证正确性和安全性的优点；提出了SM2算法的进一步应用和改进。
With the development of technology, network has become an integral part of the life. At the same time the protection to network information is becoming very important. Encryption is one of the most effective ways to protect the information. The sender will symmetrically encrypt and send the data through the network, and receiver will decrypt the information to get the plaintext. All of information in network has been encrypted. The symmetric key will be the most effectively distributed through asymmetrical key. RSA algorithm and ECC algorithm are two of the most important asymmetric algorithm. The SM2 algorithm is independently developed by the State Cryptography Administration; it improves and expands the international standard ECC algorithm. This paper introduces the advantages of authenticating correctness and safety; it also put forward the further applications and some improvements for the SM2 algorithm.
