In one embodiment a secure computer system comprises a processor and a memory module including logic instructions stored on a computer readable medium which. When executed by the processor, the logic instructions configure the processor to receive, in a secure computing environment, a portion of a data log from an application operating outside the secure computing environment, and when the portion of the data log exceeds a size threshold, to assign a timestamp to the portion of the data log, assign an identifier to the portion of the data log, create a digital signature load block comprising the portion of the data log, the timestamp, and the identifier, and store the digital signature load block in a memory module.
