摘要：Discrete Wavelet Transform (DWT) based architecture serves as a compression cum encryption system that provides dual features of high throughput multimedia compression and embedded multimedia security. The parameterized construction of the DWT compression block is used to introduce a free parameter (a) in the design. It allows building a key space for lightweight multimedia encryption. This DWT architecture provides an efficient and high-throughput reconfigurable hardware implementation through the use of Look Up Table (LUT) based constant multiplier enabling run-time reconfiguration of encryption key and also it provides multiplier less hardware implementation
