However, vulnerabilities and threats to smoke/CO alarms have not been well-studied. In this paper, through interconnect, a power replay attack has been studied in order to trigger a false alarm. The experimental results demonstrate the smoke alarm can be manipulated. This paper also concentrates on providing a sequence of security methods to defend the smoke alarm system. In future, how to protect smart detectors against attacks will be studied as this can force them to leave high-quality mode of operations.展开更多

Current systems have the capability to reduce damages, but implementations for the reduction are either outside of the system or are implemented in a manner that is unintuitive or confusing to users. In this paper, an access control method has been proposed that focuses on the alleviation of damage caused by such applications through the interactions between the user, application, and computer system. In details, the proposed model would work as a module or an interceptor to delegate permissions to applications through user input by using existing system calls. The evaluation about the proposed model as well as the first step implementation can show better security protection than existing systems.展开更多
