网格编码quantization的公钥信息隐藏
Trellis-coded quantization for public-key steganography
摘要：
本文研究了在有一个被动管理员的情况下的公钥隐写。其目的是将秘密信息隐藏在封面文件中，而不会使管理员产生怀疑，并且没有任何秘密秘密密钥共享。尽管已经进行了实际尝试来提供对该问题的解决方案，但是与最近的数据隐藏技术相比，它具有较差的灵活性（因为嵌入和解码步骤高度依赖于覆盖信号统计）和较小的容量。使用相同的框架，本文探讨了使用网格编码量化技术（TCQ和涡轮TCQ）设计一个更有效的公钥计划。在音频信号上的实验表明，考虑到Cachin的安全标准，该算法有很大的改进。
英文摘要：
This paper deals with public-key steganography in the presence of a passive warden. The aim is to hide secret messages within cover-documents without making the warden suspicious, and without any preliminar secret key sharing. Whereas a practical attempt has been already done to provide a solution to this problem, it suffers of poor flexibility (since embedding and decoding steps highly depend on cover-signals statistics) and of little capacity compared to recent data hiding techniques. Using the same framework, this paper explores the use of trellis-coded quantization techniques (TCQ and turbo TCQ) to design a more efficient public-key scheme. Experiments on audio signals show great improvements considering Cachin's security criterion.
