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.

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。

The soft layer of ECC media usually possesseshigh saturation magnetization and also high demagnetizing energy density.

ECC介质由交换耦合的软磁层与硬磁层构成，它是通过软磁层与硬磁层的磁矩在磁化反转过程中的非一致转动来达到降低矫顽力的效果，而无外场时热反转仍为一致转动，因而能保持较高的热稳定性。
