摘要
针对网络安全问题,国内外研究人员试图从信任的角度来解决和加强网络安全并且提出了许多信任模型,但并没有形成一致的观点。本文结合信任特性和网络安全的特点,提出了一种基于D-S证据理论的多维信任模型,给出了网络中多维信任的概念并提出了多维信任的计算方法和合并规则。实验表明,该信任模型能够合理地有效地遏制恶意实体的行为,降低网络中不安全因素对整个网络的影响。
About the network security problem, domestic and foreign researchers have tried to solve it from the perspective of trust to enhance network security and a lot of trust models have been proposed in the literature. However, a universally agreed trust model has not been seen yet. Combining features of trust and network security, a DST-Based Multi-dimensional Trust Model is proposed, the multi-dimensional trust conception is introduced, multi-dimensional trust computing method and trust combination rules are given. Simulation studies show that the model is able to restrain the malicious entities ’ actions more effectively, and reduce the influence of unsafe factors of the entire network.
