Abstract—The Internet of Things refers to uniquely distinguishable devices communicating with each other. Communication is largely on resource-constraint devices which would generate large volumes of data, the security, authenticity, and integrity of devices being essential. SPONGENT-88 variant of the SPONGENT family is a lightweight Hash algorithm suitable for authenticating resource-constrained devices in an IoT environment or WSN (Wireless Sensor Network) as it has the smallest footprint in comparison with the sponge-based Hash algorithm. Conventionally most of the security primitives are realized using more sequential logic which leads to an increase in the area occupied and latency. This work proposes a serialized architecture with a balance in sequential and combinational logic that uses lesser flipflops with a 21% increased performance for throughput/slice in comparison with reported works on target LUT-6 technology on FPGA, realized on the 14.2 ISE design suite. The work has a 4.6% decrease in quiescent power and dynamic power reported on the 14.2 ISE design suite for LUT-6 technology. This work has also achieved a Gate-Equivalence (GE) utilization for the proposed design on TSMC180 technology for a data path of 88-bit, while the proposed work reports 1204GE. In this work, a scaled-up architecture of the proposed SPONGENT-88 is realized for SPONGENT-128 and SPONGENT-224 as these variants provide improved security bound and is in comparison with the security provided by SHA-1 and SHA-2 algorithms. The scaled architecture for the latter variants of SPONGENT algorithms has achieved reduced Gate-Equivalence (GE) in comparison with the reported work.
