There has been an increasing concern for the security of multimedia transactions over real-time embedded systems. Partial and selective encryption schemes have been proposed in the research literature, but these schemes significantly increase the computation cost leading to tradeoffs in system latency, throughput, hardware requirements and power usage. In this paper, the authors propose a lightweight multimedia encryption strategy based on a modified Discrete Wavelet Transform (DWT) which they refer to as the Secure Wavelet Transform (SWT).
