Protection is one of the key factors to be considered in application development. Every application should follow some security mechanisms to be free from fraudulent users. One of the important criteria to ensure security is Access control. [4]The reliability and security of the cloud and user are assured and effectively guaranteed during its interaction in the cloud computing environment. But these traditional models were unable to determine the vulnerability and ambiguity created by these open conditions. So the main focus throughout the evolution of new access control methods is on creating a mutual trust relationship between both interaction parties. The paper proposes a mutual access control model which is trust-based (MTBAC). Trust relationships between both interaction bodies are secured by mutual trust mechanisms. This model takes both the cloud service node’s trustworthiness and user’s action trust into consideration.

The paper addresses an important problem related to automation of simulation modeling of queue systems using high-performance computing. There is a large spectrum of tools for the simulation modeling of such systems. However, these tools often do not use the possibilities of subject-oriented high-performance computing in full. The purpose of the study is the development of the new tools for automation of the simulation modeling of queue systems in a heterogeneous distributed computing environment. To this end, we develop specialized applications for parameter sweep computations in such an environment. A methodology of the application development is based on the integrated use of methods of the conceptual and wireframe programming, methods of the computations planning and resources allocation, methods of parameter sweep computations, and methods of the data analysis. We develop the toolkit named SIRIUS III for the simulation modeling of queue systems using high-performance computing. In addition, we design a conceptual model that represents knowledge about both the subject domain of solved problems and computing environment. Using the proposed toolkit, we solved a number of problems related to warehouse logistics. Computational experiments showed the high scalability of parameter sweep computations on heterogeneous resources.
