Abstract: Various embodiments are directed to providing integrity protection for a system management mode. During initialization, a hash value of a system management mode control routine may be determined. Subsequently, during operation, the hash value may be compared to a hash value of a system management mode control routine to be executed. The system management mode control routine to be executed may be determined to be authentic if the hash values are the same.
Abstract translation: 各种实施例针对为系统管理模式提供完整性保护。 在初始化期间,可以确定系统管理模式控制例程的散列值。 随后,在操作期间,散列值可以与要执行的系统管理模式控制例程的散列值进行比较。 如果散列值相同,则要执行的系统管理模式控制例程可以被确定为可信的。 p>
