摘要
为加强网络信息安全,该文提出了一种基于m-序列的多智能体协作的信息隐藏模型,并提出以鲁棒性、安全性和通信容量作为评价信息隐藏系统的性能指标。实现了基于多智能体协作的信息隐藏系统,该系统通过多智能体协作加强信息隐藏的鲁棒性,使用多智能体发送信息,加大了隐蔽通信的容量。仿真结果表明:基于多智能体的信息隐藏算法未对特殊位进行处理,因而没有网络包被防火墙过滤,隐藏的信息未丢失;防火墙类产品对于使用包填充类算法隐藏的信息的安全性影响非常大,对于使用基于多智能体算法隐藏的信息的安全性几乎没有任何影响。
A model of multi-Agent collaboration way to hide information based on m-serial is presented to protect security of network information. Capacity, robustness and security are proposed to e- valuate the performance of network steganography system. According to the mode, a network steganography system is developed. The system strengthens the robustness of steganography by multi-A- gent cooperation, sends information by multi-Agent, and the capacity of covert communication is increased. Simulation results show that the hiding information is not lost because the network steganography algorithms do not deal with the special bits of network packet, so that it is not interfered by the fire wall ; impact of the security products like firewall on the security of hiding imformation is very large for those algorithms which hide imformation by filling special bit of network packet, but these products play little role on the network steganography system.
