    Cryptographic algorithm optimisation
    (2015) Dhanuka, S.K.; Sachdeva, P.; Shaikh, S.S.
    Lightweight cryptographic algorithm is intended for implementation in resource constrained devices such as smart cards, wireless sensors, Radio Frequency Identification (RFID) tags which aim at providing adequate security. Hummingbird is a recent encryption algorithm based on ultra-lightweight cryptography and its design is based on blend of block cipher and stream cipher. This paper presents design space exploration of the algorithm and optimisation using different architectural approaches. It provides comparative analysis of different models of substitution box, cipher and encryption blocks. � 2015 IEEE.

    VLSI implementation of efficient image watermarking algorithm
    (2015) Dhanuka, S.K.; Sachdeva, P.; Shaikh, S.S.; Alevoor, S.
    Protection and authentication of digital multimedia content during transmission has become very important with the ongoing development in communication and networking field. Aiming at this popular research topic of recent time, this paper presents a comparative analysis of different watermarking techniques performed in MATLAB. It also presents a robust VLSI architecture for watermarking which survives most of the attacks to which data is exposed on internet and contributes towards anti-plagiarism rule. This paper exhibits the ASIC implementation of an efficient digital watermarking algorithm for images based on frequency domain Discrete Wavelet Transform and spatial domain bit plane slicing. � 2015 IEEE.
