Secure Hybrid Operating System “Linux over Fenix”

The article discusses an approach to the construction of secure data processing systems based on the hybrid operating system technology, making it possible to use several different operating systems simultaneously on the same computer and arrange for an interaction between those. The Fenix secure operating system developed at the Software Security Laboratory(SSL) of the St. Petersburg State Polytechnical University (SPSPU) is proposed to be used as a host operating system, while the popular Linux OS — as a guest operating system, to ensure compatibility with commonly used applications.
