Data protection educational material requirements

This article is devoted to data protection educational material requirements. Here we describe modern data protection principles, selection guideline for application-oriented programming language and mathematical system, the necessity of applying network analyzers and memory editors, and criterions to information security problems. Multi-layer information security consideration combines studying of cryptography and steganography algorithms. We propose to use the method for hidden distribution of information over set of telecommunication network channels, which provides to apply data protection original algorithm for each particular channel. According to multi-layer information security principles, distributed information is encrypted and it is hidden steganographically over different kinds of containers. Here algorithmic barrier is utilized as a complete linkage of protected data blocks. Moreover this information diffuses not only spatially but also in time. Also we describe a method for network steganography based on information hiding over length of network packet.
