摘要
PDM系统的安全性问题是一个复杂的系统工程。本文介绍了当前密码学的前沿技术和常用的加密算法,并着重论述了单向散列加密算法的原理和AES加密算法的原理,并创造性的对各种加密算法进行了安全性和效率对比,筛选出了适合PDM系统软件的、安全的、高效的加密解密算法。
The security of the PDM system is complicated system engineering. For the purpose, some frontier technology and common used algorithm are introduced in my paper,emphasizing on the principle of the encryption and decryption algorithm. The contrast of different algorithms on security and effection are also presented, and then select out one fit for the PDM system.
