The security factor is one of the major concerns in today’s world. As security is the breath of communication, as much as we can make our communication system secure, the system will be more trustworthy and be more restricted to snap as well as can save guard from the unauthorized attempt. Either symmetric or asymmetric encryption was used in the earlier method to ensure data security. However, any of them alone makes the system either unsecured or time-consuming. In our thesis work, we have used both the techniques together to make the system as much as reliable and also to make it faster using the hybridization of asymmetric RSA encryption and symmetric modified vigenere technique. This hybridization method sends the vigenere table as an encrypted string using an asymmetric process with the collaboration of the RSA encryption algorithm where the string will be encrypted by the public key generated by the receiver. Later the string will be decrypted using the receiver’s private key. Therefore, we can claim that the extended vigenere method with the collaboration of RSA makes the overall communication more secure, stable, reliable, and faster.

Secure Authentication

To send data over the network, devices need to authenticate themselves within the network. After authentication, the device will be able to send the data in-network. After authentication, secure communication of devices is an important task that is done with an encryption method. IoT network devices have a very small circuit with low resources and low computation power. By considering low power, less memory, low computation, and all the aspect of IoT devices, an encryption technique is needed that is suitable for this type of device. As IoT networks are heterogeneous, each device has different hardware properties, and all the devices are not on one scale. To make IoT networks secure, this paper starts with the secure authentication mechanism to verify the device that wants to be a part of the network. After that, an encryption algorithm is presented that will make the communication secure. This encryption algorithm is designed by considering all the important aspects of IoT devices (low computation, low memory, and cost).
