A Security Scheme based on Location for Wireless Sensor Networks
نویسنده
چکیده
A pair wise key pre-distribution scheme based on the concept of the Overlap Key Sharing (OKS) and clusters for wireless sensor networks is proposed. This strategy divides the sensing area into square cells and logical groups and distributes key information to the sensor nodes by employing the OKS scheme. Sensor nodes establish their secure communication through using their keys. Analysis and comparison demonstrate that this scheme has good network connectivity, effectively reduces storage cost and enhances the security for WSNs and provides flexible security grades.
