    • Described is an independent computation environment that is built into one or more hardware components of a computer system, wherein the independent computation environment hosts a logic that measures the health of other software code that executes in memory. Examples of ways to measure health include performing a mathematical computation such as a computing a hash/digital signature on the software code in the memory, and/or evaluating statistical information related to the execution of the code and/or the code's being loaded into memory. By executing the logic in an independent computation environment, the health of software code may be measured against policy/metadata in a tamper-proof or tamper-resistant environment. When the software code measurement does not comply with the policy, some action may be taken action to penalize the computer system.
    • 描述了内置在计算机系统的一个或多个硬件组件中的独立计算环境,其中独立计算环境承载测量在存储器中执行的其他软件代码的健康状况的逻辑。 衡量健康的方法的示例包括执行诸如在存储器中的软件代码上计算散列/数字签名的数学计算,和/或评估与代码的执行相关的统计信息和/或被加载到存储器中的代码 。 通过在独立的计算环境中执行逻辑,可以根据防篡改或防篡改环境中的策略/元数据来衡量软件代码的健康状况。 当软件代码测量不符合该策略时,可采取一些行动来惩罚计算机系统。
