Internet of things authentication based on chaos-lightweight bcrypt

Abstract EN

—Authentication on IOT is to identify things such as (users, nodes, devices, and data accessing) by authorized manner using private information based on cryptography methods and techniques to provide a robust secure operation over the IoT.

Each devises and sensors need to be authorized to connect nodes and other devices for transferring data through the network.

This paper proposed new authentication technique between nodes, computing devices, and sensors based on proposed lightweight Bcrypt encryption with 4-D chaos system.

The proposed lightweight Bcrypt authentication contain three stages (SHA1-128bit, HMAC 256 -bit, and modified chaos-Blowfish with 128-bit).

These three stages modified to be compatible to IOT devices with high speed.

For getting a strong hashing security, the four dimension chaotic system (hybrid from Lorenz system with logistic chaotic maps) used to combine with above three stages.

Testing results show proposed algorithm passing the NIST tests with CPU cycles in lightweight ranges
