Their influence on society is very strong. The Internet technology has provided additional opportunities for a new development level of education, design and production. Associations and scientific conferences in the field of online engineering that appeared, seek to foster practices in education and research in higher education institutions and the industry on online engineering. A particular challenge for online engineering is how to extend the traditional equipments and laboratories to the Internet. A method of the embedded systems design with using online laboratory is described in this paper. Also, in this paper the experimental set of remote laboratory which allows carrying out hardware/software oriented design of the embedded control system of a mobile platform is considered.展开更多

The result shows that the covert channel＇s algorithm, which we implemented if, set correct, the messages of this covert channel might go through the gateway and enter the local area network.展开更多
