数据库内外网非法访问信息还原优化仿真研究

摘要

对数据库内外网非法访问信息还原优化的研究,能有效提升网络数据库安全性.对非法访问信息精确还原,需要对已知数据精准采集,并对其进行反复的核化迭代,促使已知访问数据呈线性分布状态,完成信息还原.传统方法将数据挖掘引入到对访问数据的过滤过程中,但处理后的信息数据线性度差,导致还原效果不好.提出多核复合的内外网非法访问信息采集和精确还原方法.设置非法信息采集间隔时间,计算出数据库非法访问信息的地址,采用SSL加密机制对采集的信息进行加密传输,对同类非法访问信息中的已知数据进行反复的核化迭代,促使已知同类非法访问信息在超高维欧氏空间中呈线性分布状态,融合于KRR组建回归方程,完成非法访问信息采集和精确还原.仿真结果表明,所提方法具有较强的鲁棒性,可以提升数据库内外网信息的安全性.%This article proposes a method for collection and accurate recovering of illegal access information in in ternal and external network based on multinuclear combination.Firstly,our research set collecting interval time of illegal information,worked out address of illegal access information of database,and carried out encryption transmission for the collected information using SSL encryption mechanism and carried out coring iteration for the known data repeatedly in the same kind of illegal access information.Then,the research prompted the known same kind of illegal access information to present state of linear distribution in high-dimension Euclidean space and built regression equation integrated with KRR.Simulation results show that the method has better robustness.It can improve security of information in the internal and external network of database.
