Secure hierarchy systems to safeguard private communications

In crisis communication, satellite communications is the only independent solution that is reliable in any given situationDemanding that the satellite terminals used delivers solutions that are stable and secureTherefore, continuous work is being done on our Satcube Ku terminal to keep developing secure and stable communications. Finding performance efficient methods that live up to our high security standards and that are easy to implement is challenging work. To this end Magnus Harryson, our new team member, has been investigating if using Role-Based Access Control, RBAC, in combination with the logic language Datalog could form an effective method to handle access control of tasks within an embedded system.
