This book introduces a zero-overhead security scheme for real-time embedded digital image processing systems. The Discrete Wavelet Transform (DWT) compression block is constructed using a parameterized approach, introducing a free parameter into the design. To create this parameterized DWT compression block, we utilize a biorthogonal wavelet filter bank. This approach allows for the establishment of a key-space for lightweight multimedia encryption. The parameterization yields rational coefficients, resulting in an efficient fixed-point hardware implementation. Achieving a clock speed of over…mehr

Produktbeschreibung
This book introduces a zero-overhead security scheme for real-time embedded digital image processing systems. The Discrete Wavelet Transform (DWT) compression block is constructed using a parameterized approach, introducing a free parameter into the design. To create this parameterized DWT compression block, we utilize a biorthogonal wavelet filter bank. This approach allows for the establishment of a key-space for lightweight multimedia encryption. The parameterization yields rational coefficients, resulting in an efficient fixed-point hardware implementation. Achieving a clock speed of over 244 MHz on a Xilinx Virtex 2P FPGA, this method proves highly effective. A comparison with existing approaches highlights the significant advantages in terms of throughput and hardware overhead when integrating security features into the DWT architecture.
