Lightweight VLSI Design of Hybrid Hummingbird Cryptographic Algorithm
Due to drastic increase in e-commerce, there is need for real time implementation of light weight cryptographic algorithms to be used in low cost smart devices such as RFID tags, smart cards, wireless sensor network, PDA's, etc. Hummingbird is a latest ultra-lightweight cryptographic algorithm tailored for extreme resource constrained devices having limited bandwidth and processing capabilities. In this paper, the authors describe the hybrid model of hummingbird and its software implementation is also presented. The digital design is verified at the software platform using ModelSim SE 6.2b simulator. Their experimental results verify the simulation as well as the behavioral description of the approach designed.
