A New Model of Light Weight Hybrid Cryptography for Internet of Things

To achieve higher security for IoT devices, in order to protect their network connection and commanding, lightweight encryption standard or techniques will be used for encryption and decryption to avoid the intruders to access the information. As small IoT devices don't have huge processing or storing power so they can only support light protocols. One standard should be strong enough to protect and light enough to support light processor devices. In an existing network, there are very few lightweight cryptography standards which are used in the protection of devices. An intruder can break through and control the devices without physical appearance if we do not secure our network. To overcome this issue, we have created new hybrid cryptography using one well-trusted fusion of RECTANGLE SPECK & LED. In the analysis work implementation of our hybrid system will generate variable size key with minimum time complexness and better security that is with competence suited in real time cryptography. A solely approved person can access the information. During this context, a key is the fusion of the various specialists for taking a final decision.
