An Efficient Biometric Authentication Protocol for Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are spreading rapidly due to their flexibility to communicate which demands a secure environment. The most important requirements of WSN security are confidentiality, authentication, and integrity. User authentication is necessary for legitimate access control in WSNs. Sensors have limited processing power, bandwidth, memory, and limited communication abilities. Significantly, the system must produce an authentication method to confirm if the user is legal or not. In this paper, the authors present a solution based on biometric and adapt it for a WSN environment. The proposed protocol involves simple operations and light computations.
