Abstract-The Internetof things required the intercommunication between machine to machine without involvement of human commands. As there is no involvement of human being, only machines has to communicate with each other, the security concerns are the major concern in the field of IoT. To minimize the security concerns, the proposed work is to implementation of architectural based security mechanism like encryption techniques, secure protocol, various security certificates and authentication such as password protection, in the architecture of the Internet of things IoT. The different security mechanism is implemented on each layer of IoT architecture according to the property and characteristic of the layer.
-The security is the major key element for the acceptance of IoT as IoT is the network of smart objects, capable enough to automate the Things of Internet of Things. Here in this paper we have successfully implemented the security mechanism in the network access layer, where basically the data encryption and decryption process is implemented. The platform used for IoT is thingworx and user interface which act as client who communicates with the IoT platform is a web application. This web application fetch the data from the sensor and send the encrypted data to the thingworx and thingworx will decrypt that data and sets a status or make a decision on received data and again encrypt the data and send it back to user interface in encrypted form.
