Recent developments in sensor networking emphasized the need for integration of sensor networks with the cloud. This improves the processing power and battery life of the sensor nodes. Once the sensor data is routed to the cloud, possible measures need to be adopted to secure the sensor data. Thus, strict authentication checks have to be provided to facilitate authorized customers to utilize the services provided by the cloud in the form of sensor data. In this paper, we present an authentication system by employing the multi-level authentication technique in securing the sensor data in cloud. This technique generates/authenticates the password in multiple levels to access cloud services. Thus, the proposed scheme helps in improving the authentication level by order of magnitude as compared to the existing technique. We modeled the proposed system using Petri nets.
