Abstract:
A computing device is provided including a motherboard including a control module, a first trusted platform module (TPM), and a second TPM. The control module directs security operations to the first TPM, wherein the control module is operable to detect whether or not the first TPM is damaged, and wherein the control module, in response to detecting that the first TPM is damaged, is operable to direct subsequent security operations to be performed by the second TPM. A computer program product is also provided including non-transitory computer readable storage media embodying program instructions executable by a processor to direct security operations to a first TPM coupled to a motherboard of the computing device, detect whether or not the first TPM is damaged, and, responsive to detecting that the first TPM is damaged, direct subsequent security operations to a second TPM coupled to the motherboard of the computing device.
