Hybrid improved technique for data security and authentication for RFID tags

In the modern era, the internet of things are gaining lot of attention because its provides a connecting of all devices with the internet. The users can access the all devices wirelessly from anywhere. The internet is public available network, anyone access the network. So, to provide the user's security and privacy data security and authentication is required. To provide security cryptography algorithms used but the limitation is that the standard algorithms which are approved by NIST such as AES large block, key size, and memory consumable and their performance not up to mark in resource constraint devices. In this paper, a hybrid lightweight improved technique is proposed for data security and authentication for RFID tags. The performance analysis for the proposed technique is done and compare with the existing algorithm. The result shows that the hybrid technique resolve brute force, linear and differential cryptanalysis attacks.
