Improving Key Management Scheme Supporting Node Mobility in Heterogeneous Sensor Networks using Collision-Keys
Wireless Sensor Networks (WSNs) consist of a large number of sensor nodes that are batteries powered, equipped with limited memory and computational capabilities. These constrained devices face many security threats and thus there is a need of some cryptographic mechanism for secure communication. Key distribution is of critical importance to provide security in WSNs. Till now a number of key d...
متن کاملA novel key management scheme for heterogeneous sensor networks based on the position of nodes
Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...

متن کاملAn Authentication and Key Management Scheme for Heterogeneous Sensor Networks
Recently, wireless sensor networks have attracted the attention of research comunity due to its numerous applications especially in mobility scenarios. however it also increases the security threats against confidentiality, integrity and privacy of the information as well as against their connectivity. Hence a proper key management scheme needs to be proposed to secure both information and conn...
متن کاملAn effective key management scheme for heterogeneous sensor networks
Security is critical for sensor networks used in military, homeland security and other hostile environments. Previous research on sensor network security mainly considers homogeneous sensor networks. Research has shown that homogeneous ad hoc networks have poor performance and scalability. Furthermore, many security schemes designed for homogeneous sensor networks suffer from high communication...
