摘要 在本文中我们首先给出了阈下信道的一般模型和含有阈下信道的密码系统的定义,讨论了信任度和安全度两个指标。然后我们对目前的构造技术进行了系统的分类,对各类方案的容量、计算复杂度及边信息量等进行较为深入的研究,并讨论了认证码中的阈下信道与一般阈下信道的差别。我们首次提出了边信息协商的概念,并给出了几个实现方案。 A definition of cryptosystem with subliminal channels and a model of subliminal channels are given in this paper. And two index, confiding degree and security degree, are also discussed. Then a systemic classification of subliminal channels techniques is given. And a sound research on capacity, computational complexity and side information has also been done- We then discuss the difference between the subliminal channels in authentication codes and the one in other system. Finally,a concept of side information exchange is first presented and some schemes are given.
