概要 |
To address computer security issues, a hardware-based intrusion detection technique is proposed. This uses the dynamic program execution behavior for authentication. Based on secret key information, a...n execution behavior is determined. Next, a secure compiler constructs object code which generates the predetermined execution behavior at runtime. During program execution, a secure profiler monitors the execution behavior. If the profiler cannot detect the expected behavior, it sends an alarm signal to the microprocessor for terminating program execution. Since attack code cannot anticipate the execution behavior required, malicious attacks can be detected and prohibited at the start of program execution.続きを見る
