A New Algorithm for Double Scalar Multiplication over Koblitz Curves
J. Adikari, V. S. Dimitrov, R. J. Cintra
Koblitz curves are a special set of elliptic curves and have improved performance in computing scalar multiplication in elliptic curve cryptography due to the Frobenius endomorphis…
A Single-Channel Architecture for Algebraic Integer Based 88 2-D DCT Computation
A. Edirisuriya, A. Madanayake, R. J. Cintra +1
An area efficient row-parallel architecture is proposed for the real-time implementation of bivariate algebraic integer (AI) encoded 2-D discrete cosine transform (DCT) for image a…
A Row-parallel 88 2-D DCT Architecture Using Algebraic Integer Based Exact Computation
A. Madanayake, R. J. Cintra, D. Onen +4
An algebraic integer (AI) based time-multiplexed row-parallel architecture and two final-reconstruction step (FRS) algorithms are proposed for the implementation of bivariate AI-en…
Fragile Watermarking Using Finite Field Trigonometrical Transforms
R. J. Cintra, V. S. Dimitrov, H. M. de Oliveira +1
Fragile digital watermarking has been applied for authentication and alteration detection in images. Utilizing the cosine and Hartley transforms over finite fields, a new transform…
