Fine grained control of secure access in wireless sensor networks under DDoS attacks
In wireless sensor networks,user behavior is often dynamic and unpredictable,posing a high challenge to the devel-opment of fine-grained control strategies for secure access in wireless sensor networks.The normal trust cloud model has flexibility and can adjust the parameters and weights of the trust measurement of wireless sensor network user behavior in real time according to changes in network environment and user behavior,thereby making the measurement results timely and accurate.Therefore,a fine-grained control method for secure access of wireless sensor networks under DDoS attacks is proposed.Establish a trust mea-surement index system for wireless sensor network access user behavior based on the access characteristics of wireless sensor net-works.Adopt a normal trust cloud model to measure user behavior trust,introduce user behavior trust measurement values into ac-cess control protocols,and combine protocol initialization,decryption key design,etc.to achieve fine-grained control of wireless sensor network security access.The experimental results show that using this method for fine-grained access control yields good re-sults and can be widely applied in practice.
