Web-Proxy-Based Authentication and Authorization Mechanism Against Client-Based HTTP Attacks

There has been a huge development in how to read a data from sensor device such as infrared (IR) device, temperature device, etc. Sensor data collection has wide issues of information security. Information security is also the current topic of discussion due to its use in application in various fields. There are number of users having different user roles with smart devices. These personnel use devices for various purposes like access the information from various devices such as wireless sensors so that a secure and efficient mutual authentication and authorization scheme is used in the smart grid network to prevent various insider and outsider attacks on information or data. Therefore, proposed work design novel approach to overcome that attack, malicious user and device by authentication and authorization. The technique of authenticate authenticates each user role dynamically using a signature based access control and verifies the identity of user together with the device. Access control mechanism not only prevents unauthorized access but also prevent misuse of data. Existing system generates shared key for each session but it generates huge overhead and not suitable for the real-world applications so in proposed system we used public key cryptography to reduce the overhead.
