摘要：
A processing system features random access memory (RAM), a processor, and a trusted platform module (TPM). When the processing system enters a sleep mode during which the RAM is to stay powered, the processing system may measuring a VMM and one or more secure VMs in the processing system. However, the processing system may not measure or encrypt all of system memory. Upon resuming from sleep, the processing system may verify the measurements, to ensure that the VMM and secure VMs have not been tampered with. Other steps may include sealing encryption keys to the TPM, while preserving the blobs in memory. Other embodiments are described and claimed.
