摘要
为了保障大数据计算的安全,结合大数据安全的安全研究和可信云的概念,提出一个大数据计算下SAT的双向防御系统模型。该模型通过动态安全因子对用户数据证据进行规范;逐步确定各行为证据的安全权限,实现行为的可靠性测试,为用户提供最大限度的安全防御。实验结果表明,该系统模型可以有效地提升大数据的数据安全,降低黑客的恶意攻击行为,从而提高大数据分析效率。
In order to guarantee the safety of big data calculation, and based on the concepts of security research and trustwor- thy clouds of big data safety,this paper put forward a hi-directional defense system SAT model under big data calculation. The model regulated users＇ data evidence through dynamic safety factors, gradually determined the security permission of various behavior evidences, achieved reliable test of behaviors, as well as offered safety defense to users to the maximum limit. Experi- mental result shows that the system model can effectively improve the data safety of big data and reduce the hostile attack of hackers so as to improve the analysis efficiency of big data.
