Abstract
Cloud computing environment has been developed rapidly and becomes a popular trend in recent years. It provides on-demand services to several applications with access to an unlimited number of resources such as servers, storage, networks. Wireless Sensor Network, on the other hand, has been enormously progressing in various applications and producing a considerable amount of sensor data. Sensor networks are based on a group of interconnected small size sensor nodes that can be distributed over different geographical areas to observe environmental and physical phenomena. Nevertheless, it has limitations concerning power, storage, and scalability that need to be addressed adequately. Integrating wireless sensor networks with cloud computing can overcome these problems. Cloud computing provides a more secure and high available platform for effective management of sensor data. This paper proposes a framework to secure the dataflow of sensor devices from wireless sensor networks to cloud computing using an integrated environment. The framework presents an authentication scheme to validate the identity of sensor devices connected to the cloud environment. Furthermore, it provides secure environments with high availability and data integrity.
