This article focuses on methods of training students specializing in applied informatics in economy to build up skills of posting and promoting websites in the Internet. The back¬ground of emergence of New economy in the Internet, the types of the most popular economic relations and means of their implementation are briefly described. An example of case-study of II Module of Internet Economy is given. Case-studies are used as methodology.

Intensive growth of the processors power, bringing to nothing many traditional cryptographic decisions, stimulates development of new principles of coding. Application of the dynamic determined chaos theory is one of alternative approaches here. In this work two algorithms of the information coding on the basis of the determined chaos are developed and investigated. As the generator of chaos it is used Lorentz attractor. Optimum parameters of coding are found.
