基于混沌的协同商务数据完整性验证方法

针对目前协同商务系统具有多方协同合作、实时数据传输和信息安全性高的要求,构建了协同商务系统数据完整性的实现模型,提出了一种基于混沌动态S盒的带密钥的Hash函数的数据验证方法。利用混沌动态S盒和函数查找表来生成具有混沌特性的Hash散列值,提高了系统的实时性能。理论与实验结果表明,该方法不仅具有很好的单向性、初值和密钥敏感性,而且运行速度快,易于实现。

Data integrality validation of collaborative business based on chaos

To fulfill the requirements of multi-party collaboration,real time data transmission and high information security,a realization model of data integrality in collaborative business systems was proposed.A data validating method with Hash function was put forward which is based on chaotic dynamic S-box.This method improves real time performance of systems by using the chaotic dynamic S-box and function check table to generate chaotic Hash array of discrete data.Theoretical and experimental results show that the proposed method possesses strong one-way property,sensitivity to initial conditions and it is easy to implement with high speed.
