摘　　要：在处理用户与权限中心的密钥时,传统加密方法存在对应层次不均和异构数据库加密时间长等问题。对此,文章提出了一种基于B/S结构的异构数据库加密算法,首先对比了C/S与B/S结构的优缺点;其次构建了基于B/S结构的异构数据库加密体系框架。该框架包括1套全面的密钥管理机制,用于生成各级权限管理中心的密钥,以及用户在对应权限中心的密钥与用户主密钥。通过使用访问策略树对服务器端的明文数据进行加密,该算法可将需要保护的数据转换为密文形式。仿真结果显示,该算法不仅能有效完成异构数据库加密,达到保护数据库安全的目标,且响应时间相比传统方法有显著提升。Traditional encryption methods have problems such as uneven corresponding levels and long encryption time for heterogeneous databases when dealing with user and permission center keys.In this regard,this article proposes a heterogeneous database encryption algorithm based on the B/S structure.Firstly,the advantages and disadvantages of C/S and B/S structures are compared.Secondly,a heterogeneous database encryption system framework based on B/S structure was constructed.This framework includes a comprehensive key management mechanism for generating keys for various levels of permission management centers,as well as user keys in corresponding permission centers and user master keys.By using an access policy tree to encrypt plaintext data on the server side,this algorithm can convert the data that needs to be protected into ciphertext form.The simulation results show that the algorithm can not only effectively encrypt heterogeneous databases and achieve the goal of protecting database security,but also significantly improve response time compared to traditional methods.
