摘　　要：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。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.
