Abstract
In one aspect, a method for securing a device includes receiving a first set of boot information of a device, receiving a first cryptographic proof of the first set of boot information, receiving a second set of boot information of the device, receiving a second cryptographic proof of the second set of boot information, comparing the first set of boot information and the second set of boot information, and, upon determining that the first set of boot information and the second set of boot information are different, determining whether differences between the first set of boot information and the second set of boot information are permitted. The method may also include generating an alert upon determining that differences between the first set of boot information and the second set of boot information are not permitted.
