Extending Platform Trust During Program Updates

An information handling system comprising:

• one or more processors;
• a memory coupled to at least one of the processors;
• a display accessible to at least one of the processors;
• a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
• generating a first hash value of a computer program in response to receiving a request to execute the computer program;
• in response to determining that the first hash value fails to match a second hash value, matching the first hash value to a third hash value, wherein the second hash value was generated subsequent to installing the computer program, and the third hash value was generated in response to modifying the computer program;
• and
• executing the computer program in response to matching the first hash value to the third hash value.

A computer program product stored in a computer readable storage medium, comprising computer program code that, when executed by an information handling system, causes the information handling system to perform actions comprising:

• generating a first hash value of a computer program installed on the information handling system in response to receiving a request to execute the computer program;
• in response to determining that the first hash value fails to match a second hash value, matching the first hash value to a third hash value, wherein the second hash value was generated subsequent to installing the computer program, and the third hash value was generated in response to modifying the installed computer program;
• and
• executing the installed computer program in response to matching the first hash value to the third hash value.
