Abstract : Hummingbird is a Lightweight Authenticated Cryptographic Encryption Algorithm. This light weight cryptographic algorithm is suitable for resource constrained devices like RFID tags, Smart cards and wireless sensors. The key issue of designing this cryptographic algorithm is to deal with the trade off among security, cost and performance and find an optimal cost-performance ratio. This paper is an attempt to find out an efficient hardware implementation of Hummingbird Cryptographic algorithm to get improved security and improved throughput by adding Hash functions. In this paper, we have implemented an encryption and decryption core in Spartan 3E and have compared the results with the existing lightweight cryptographic algorithms. The experimental results shows that this algorithm has higher security and throughput with improved area than the existing algorithms. © 2015 IEEE.
