Low Latency, Area and Optimal Power Hybrid Lightweight Cryptography Authentication Scheme for Internet of Things Applications

The Internet of Things (IoT) is proved as technologically competent connecting many devices via the internet. Now in networks transmitting a large quantity of data in a secure manner is of vital concern as communication is on the increase. Hence an efficient cryptographic methodology is essential to transmit securely. However, conventional encryption algorithms are having high computational complexity, more power consumption and high memory occupation. In this paper, low latency, area and optimal power Hybrid Lightweight Cryptography Authentication Scheme which is utilizing the 8-bit manipulation principle (HLCAS) is proposed and implemented. For such a method verification is done and validated for speech signal utilizing MATLAB. The correlation and histogram attributes have been computed to validate the security level. The complexity of the hardware is validated utilizing devices of FPGA of Spartan3E XC3S500E. From the implementation result, it has been found that the proposed HLCAS method has 5.4 ns latency, 0.9 K bytes RAM and consumes 202 mW power. From the comparison with a few reported methods it has been observed that the proposed HLCAS method outperform other methods.
