Cryptography and steganography study in Povolzhskiy State University of telecommunications and informatics (Samara, Russia) and Shumen University (Shumen, Bulgaria)

The problems of cryptography and steganography are taught at two universities - PGUTI (Samara) and the University of Shumen (Bulgaria) on basis of scientific cooperation agreement. It is a brief overview of the initial course content of "Informatics" in PSUTI. The course teaches students to learn the basic concepts of computer science and get a first glimpse of data protection methods of cryptography and steganography. There are basic ideas of published works. The first work on steganography in PSUTI were published in 2002. A few original ideas are described. For example, in the cryptosystem manage operations in addition to the exclusive-OR is used to encrypt the logical equivalence of the operation, as well as arithmetic operations of addition and subtraction. Another cryptosystem uses a secure communication protocol TCP / IP. Thus there is a deliberate change in the length of the transmitted packets. In Shumen University since 2004 cryptography and steganography are studied in several disciplines for students of «Safety Management» and «Computer Science». In 2010, the Faculty of Mathematics and Informatics in Bulgaria introduced the course «Computer Steganography» for the first time. Research on steganology was conducted by the scientific research Laboratory «Computer Security», which was developed by the cluster computer system with a total capacity of 180 GFLOPS and the energy efficiency of 19 MFLOPS / Watt. According to the study conducted by the teachers together with students at two universities, several monographs and textbooks have been published as well as articles in scientific and technical journals, more than 70 scientific papers were presented at scientific conferences, the patents were received, a number of theses have been prepared and defended. An agreement on creative collaboration was concluded between PSUTI and SHU universities.
