计算机网络加密
In this paper we present an Authenticated Encryption (AE)-based security framework for NoC based systems. The
security framework resides in Network Interface (NI) of every IP core allowing secure
communication among such IP cores.

图像原理与实践 第3版（英文）
Rendering is often done via a “pipeline” of operations; one can use this pipeline without understanding every detail to make many useful programs. But if we want to render things accurately, we need
to start from a physical understanding of light. Knowing just a few properties of light prepares us to
make a first approximate renderer.

基于小波变换的图像水印
a new reliable SVDbased image watermarking scheme that uses integer wavelet transform (IWT) is proposed
to overcome FPP and fulfil all watermarking requirements. Unlike in other schemes, the
S and V matrices of the watermark are used as secret keys, whereas the S singular vector of the watermark is embedded into the singular values of the host image. The additional secret key is obtained from the watermarked image during the embedding process to increase security and avoid FPP completely.

整数小波变换图像水印
基于整数小波变换的数字图像水印实现，The proposed watermark
embedding process is realized in integer wavelet transform (IWT) domain to defend the
robustness property. Instead of inserting the watermark bits directly in the coefficients
of cover media, an indirect embedding mechanism is proposed with the reference to a
logistic map based secret key matrix which enhance the secrecy of the proposed embedding approach. Initially, the approximate sub band of the IWT transformed cover image is
selected with the intention to embed the watermark.
