Zusammenfassung: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.
