摘　　要：数据加密技术在金属切削方面越来越受到重视。现阶段金属切削过程的数据库关键数据加密主要以TPM加密方法为主。该加密方法因受存储空间的限制,加官方式相对简单,经过一个小时的脱解,就能解密,至使金属切削过程中的关键数据存在安全隐患。提出一种金属切削数据库中关键数据加密技术,在金属切削过程中通过对用关键数据结构改变,构造金属切削数据关键数据加密自逆矩阵密钥,通过关键数据初始密钥对金属切削数据库内数据置乱,构建置乱矩阵,形成金属切削数据库中关键数据最终密钥。仿真实验证明,提出的新的金属切削数据库关键数据加持方法改善了原有的数据加密时间长易破解等缺点,提高了关键数据的安全性。Data encryption technology in metal cutting is more and more attention. At this stage in the process of metal cutting database key data encryption are mainly composed of TPM encryption method. The encryption method due to the limitation of storage space, promotion way is relatively simple, after an hour of solution, can decrypt, to make the key data in the process of metal cutting pose a safety hazard. Put forward a kind of metal cutting database key data encryption technology, in the metal cutting process by using the key data structure change, tectonic metal cutting data key data encryption keys, the inverse matrix through the critical initial key on metal cutting database data scrambling to build scrambling matrix, the formation of metal cutting database key data key in the end. Simulation experiments show that the proposed new metal cutting database key data and a method to improve the original data encryption long time is easy to crack faults, improve the security of the key data.
