基于博弈理论的访问控制奖惩激励约束机制

基于信任的访问控制问题是面向开放式网络访问控制中研究的热点。该文针对开放式网络环境下网络交互实体不诚信合作的交互访问行为，建立了基于信任的动态访问控制博弈模型，并通过设计的奖惩激励约束机制促使交互实体在自身利益驱动下理性选择系统(设计者)期望的策略，以利益作为驱动力，奖励诚信节点，惩罚约束激励不诚信节点，实现符合目标要求实体间的总体均衡状态。仿真实验和结果分析表明，在网络交互实体的不诚信访问问题上该激励约束机制是有效的。

Incentive and Restraint Mechanism of Rewards and Punishment in Access Control Based on Game Theory

Trust based access control is a research hotspot in  open network that access control is one of the importation technology of information security. For the interactive access behaviors of non-honest cooperation between network interactive entities in open network, the dynamic game access control model is established based on trust, and interactive entities are encouraged to rationally choose strategies expected by the system (the designer) driven by its own benefits through the designed mechanism. Taking benefits as the driven force, the mechanism rewards the honest nodes and punishes and restrains the non-honest nodes, and then reaches the general state of equalization between entities which meets the goal. The simulation experiment and result analysis show that the incentive and restraint mechanism is valid and necessary on the issue of non-honest access between network interactive entities.
