Secured Restful Sensor Web Enablement Services for Wireless Sensor Networks

摘要

The security and interoperability of an adopted and advanced architecture within heterogeneous components, based on the Open Geospatial Consortium (OGC) Sensor Web Enablement Architecture (SWE) and RESTful web service, requires integrity and confidentiality in the different communication protocol. The work in this paper aims to propose a security protocol of communication between the sensors based on SWE services and the adopted RESTful interface. RESTful services are considered a versatile lightweight solution relied upon by a number of advanced web services, at the same time, RESTful services suffer from a lack of meta-data description concerning security requirements. In this way, we introduce the REST security protocol to provide secure data transfer service which will implement a secure lightweight sensor message, together with its quality and its performance analysis when compared to equivalent WS-security configuration. As a result of this study, a new approach has been presented to providing security for an adopted RESTful architecture model with OGC’s SWE services. The security approach presented demonstrated the efficiency of the secured JSON message in terms of communication time and size reduction.
