摘要
文章以车间管理系统为基础原型,提出了一种基于AES和MD5的多重加密解决方案。关键技术包括:在通信过程中使用SSL对传输通道进行连接加密,使用自定义的AES算法对网络传输中的数据进行加密,并且在发送端使用自定义的MD5算法对加密后数据生成数字指纹,在接收端同时接收到的加密数据使用MD5生成相同的指纹。通过指纹效验判断数据在传输过程中是否被篡改或丢失。此方案有效地消除了数字化车间管理系统中实时采集数据在端到端的通信传输中被篡改的可能,极大可能的提高了数字化车间管理系统的安全性和可靠性。
This paper is based on the workshop management system,proposing a solution based on AES and MD5 multiple encryption. The key technologies： use SSL to encrypt the transmission channel during communication,use customized AES to encrypt the data in the network transmission and use customized MD5 generates digital fingerprints for encrypted data after encrypting the data at the sending end and generate the same fingerprint using MD5 for incoming encrypted data at the receiving end,through the fingerprint check to determine whether the data in the transmission process is tampered with or lost. This program effectively eliminates the possibility that the data collected by the digital workshop management system in real time is tampered with in the end-to-end communication transmission,which greatly improves the security and reliability of the shop management system.
