    • Embodiments of the invention are directed towards logic and/or modules stored in processor secure storage to determine whether a first platform firmware image (e.g., basic input/output system (BIOS), device read-only memory (ROM), manageability engine firmware) loaded onto a processor cache is valid. The processor executes the first platform firmware image if it is determined to be valid. If the first platform image is determined to be invalid, a second platform firmware image is located. If this platform firmware image is determined to be valid, the processor will execute said second platform image.In some embodiments of the invention, the determination of whether the first platform firmware image is valid is based, at least in part, on verification of a digital signature associated with the first platform firmware image. The digital signature may be created, for example, from a private key, wherein the digital signature is verified via a public key.
    • 本发明的实施例针对存储在处理器安全存储器中的逻辑和/或模块来确定第一平台固件映像(例如,基本输入/输出系统(BIOS),设备只读存储器(ROM),可管理性引擎固件) 加载到处理器缓存中是有效的。 如果判定为有效,则处理器执行第一平台固件映像。 如果第一平台图像被确定为无效,则定位第二平台固件图像。 如果该平台固件图像被确定为有效,则处理器将执行所述第二平台图像。 在本发明的一些实施例中,确定第一平台固件图像是否有效是至少部分地基于与第一平台固件图像相关联的数字签名的验证。 可以例如从私钥来创建数字签名,其中通过公钥验证数字签名。
