Implementation of an Efficient Hardware Architecture for Multimedia Encryption and Authentication using the Discrete Wavelet Transform

This paper introduces a zero-overhead encryption and authentication scheme for real-time embedded multimedia systems. The parameterized construction of the Discrete Wavelet Transform (DWT) compression block is used to introduce a free parameter in the design. It allows building a key space for lightweight multimedia encryption. The parameterization yields rational coefficients leading to an efficient fixed point hardware implementation.  Comparison with existing approaches was performed to indicate the high throughput and low hardware overhead in adding the security feature to the DWT architecture. The project will be implemented using HDL. Simulation will be done to verify the functionality and synthesis will be done to get the NETLIST. Simulation and synthesis will be done using Xilinx Tools.
