These devices are connected to each other in direct and indirect manner. This connection provides communication and sharing of information and data to one and another. This overall communication system uses various technologies i.e. Internet of Things, Cloud Computing, Fog Computing and other. The communication in IoT is based on Layered Structure. This layered structure helps to transfer data in safe and secure manner. For safe and secure transmission of data over IoT, user uses encryption method, but on encryption algorithm can be easily recognized by attacker so here user uses a hybrid approach. This hybrid approach is based on AES and Transpositional Reverse Algorithm. Here Transpositional Reverse Algorithm helps the users to secure the AES encryption scheme and helps to create an efficient Hybrid scheme. Keywords: Internet of Things (IoT), Cloud Computing, Data and Information Security, Encryption Algorithms, Hybrid Encryption Method, AES, Transpositional Encryption Algorithm (TEA). I. INTRODUCTION Internet of things plays a vital role to create a huge interconnected device network. The network of IoT is based on collecting and gathering information, preprocessing of these data, share the data over the network, create abstraction for hiding hardware details and show the useful extracted information on application. On the Basis of this, we can create a layered structure for Internet of Things. On the basis of working of IoT we can divide the whole processing into five parts. So the layered structure of the IoT containing all five process is drafted below, where you can easily understand the whole working phenomenon of Internet of Things [4] [5].s Fig. 1: Structure of IoT Revised Manuscript Received on May 21, 2020. * Correspondence Authors Lalit Kumar, Department of Computer Science and Engineering, Seth Vishambhar Nath Institute of Engineering and Technology, Barabanki, India.

The layered Structure of Internet of Things is drawn below: Fig. 2: Layered Structure of Internet of Things A. Perception Layer: - In the Perception Layer of the Internet of Things, Here the huge amount of data is collected from various sensors. Theses based on various field such as Environment, Medical, Natural, Chemical Biosensor, Infrared Sensor and Mobile. Here Sensor is a device, module, machine, or subsystem whose aims to detect executed events or various changes in its system and send the collected information to other electronics devices. B. Pre-processing Layer: - After collecting all data at the perception layer, a set of data is prepared. But this data is not in ready format so it needs preprocessing of data. By using the preprocessing of the data, we filter, extract and summarize data before sending it on the communication layer. So this layer is mainly helps to extract the useful information from a large amount of data that are observed by sensors in perception layer.
