Design and Development of Secure Cloud Architecture for Sensor Services

This paper is aimed at the design and development of secure cloud architecture for the Wireless Sensor Networks (WSN), in which the sensor data are represented as services and are accessed by the client applications in a secure manner with a simple authentication solution for sensors (SASS). Currently, sensor system needs an intelligent middleware to integrate with the cloud. Service Oriented Architecture (SOA), which makes use of the web services and XML technologies, will provide a solution to meet the current demands. Web services provide a mechanism for open and flexible interaction between heterogeneous systems with loosely coupled service endpoints. Further a technique based on formal specification is utilized which reduces the data volume of xml documents at a level that can be handled by the resource constrained environment of the wireless sensors. The proposed architecture will provide a scalable infrastructure for integrating heterogeneous sensor networks using a small set of powerful abstractions.
