An 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 کاملA Forward Authentication Key Management Scheme for Heterogeneous Sensor Networks
Key encryption technology is a basic technique for protecting the secrecy of transmitted data among sensor nodes in wireless sensor networks. However, sensor nodes are inherently limited by insufficient hardware resources such as memory capacity and battery lifetime. As a result, few current key management schemes are appropriate for wireless sensor networks. This paper proposes a new key manag...
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 کاملAuthentication and Key Establishment in Dynamic Wireless Sensor Networks
When a sensor node roams within a very large and distributed wireless sensor network, which consists of numerous sensor nodes, its routing path and neighborhood keep changing. In order to provide a high level of security in this environment, the moving sensor node needs to be authenticated to new neighboring nodes and a key established for secure communication. The paper proposes an efficient a...
