An efficient secure data dissemination scheme for grid structure Wireless Sensor Networks

摘要

Wireless Sensor Networks (WSNs) have been widely applied to sensing data from different environments. Owing to the resource limitations of WSNs, the data may be tampered easily during transmission. It may happen that data reach incorrect destinations or received incorrect data. It is an important issue for WSNs that base stations must receive correct data and ensure the data confidentiality. This paper proposes an efficient key management scheme and employs symmetric cryptography to secure the messages. In addition, we propose a secure routing protocol to provide a robust route. The proposed scheme further guarantees the destination should receive the data correctly.
