摘　　要：电子商务是现代商业方法，其安全性是保证其顺利开展的前提。该文论述和分析了加密技术及其在电子商务安全方面的应用现状。在对称加密体制方面，重点讨论了DES算法，给出了其在密钥管理、安全应用方面存在的问题；在非对称加密体制方面，重点研究RSA及其应用中存在的问题、ECC的优点及应注意的问题等。通过比较对称密钥加密体制和公开密钥加密体制的优缺点，总结出在电子商务中应采用混合密钥加密体制，既保证数据安全，又可提高加密和解密速度。Electronic commerce is the modern commercial method,its securiW is guarantees its smooth development the premise. This article elaborated and has analyzed the encryption technology and in the electronic commerce securiW aspect application present situation. In the symmetrical encryption system aspect, discussed the DES algorithm with emphasis, has given it in the key management, the safe application aspect exists question; The problem which in the asymmetrical encryption system aspect, studies in with emphasis which RSA and the application has the question, the ECC merit and should pay attention and so on.Through the quite symmetrical key encryption system and the public key encryption system good and bad points,summarize should use the mix key encryption system in the electronic commerce, both guarantee data security, and may enhance encrypts and deciphers the speed.
