Opis

This book introduces a zero-overhead encryption and authentication scheme for real-time embedded multimedia systems. The parametrized construction of the Discrete Wavelet Transform (DWT) compression block is used to introduce a free parameter in the design. It allows building a keyspace for lightweight multimedia encryption. The parametrization yields rational coefficients leading to an efficient fixed point hardware implementation. A clock speed of over 240 MHz was achieved on a Xilinx Virtex 5 FPGA. 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.
