Formal logical language to set requirements for secure code execution

Resumo

Presently, a special attention is paid to the problem of information security when designing and using objects of critical information infrastructure. One of the most common approaches used to secure the information processed on these objects is the creation of an isolated program environment (sandbox). The security of the environment is determined by its invariability. However, the evolutionary development of data processing systems makes it necessary to implement new components and software in this environment on the condition that the security requirements are met. In this case, the most important requirement is trust in a new program code. This paper is devoted to developing a formal logical language to describe functional requirements for program code that allows one to impose further constraints at the stage of static analysis, as well as to control their fulfillment in dynamics.
