Authentication within the X86 CPU system management mode has significant benefits for system security because the entire process is conducted within a secure environment. So, authentication itself can be guaranteed to a much higher degree. The author proposes a mechanism that can be used to access cipher information from a software application image to check code integrity for security-sensitive code. This is achievable because system management code is top priority and "invisible" to the operating system.
