摘要

提出了一种基于提升参数化双正交小波滤波器的轻量级透明JPEG 2000加密算法。通过与小波包变换的结合，进一步增强了安全性。提出了选择合适的小波包基的不同方法，并在安全性和计算复杂度之间进行了一定的控制。从压缩性能、复杂度和安全性等方面对参数化滤波器和小波包的组合方法进行了评价

Security Enhancement for Lightweight JPEG 2000 Transparent Encryption

We present improvements in lightweight transparent JPEG 2000 encryption with lifting parameterized biorthogonal wavelet filters. Security is further enhanced by a combination with the wavelet packet transform. Different methods for the selection of a suitable wavelet packet basis are presented, which also make a certain amount of control in the trade-off between security and computational complexity possible. The combined approach of parameterized filters and wavelet packets is evaluated with regard to compression performance, complexity and security
