One example provides a method for authenticating a computing device received from a manufacturer, the method including establishing a secured connection with the computing device, receiving, from the computing device, a first set of security artifacts, and retrieving, from a secure cloud storage location, a second set of security artifacts, the second set of security artifacts including the EK public key and the PCR values for the computing device obtained during manufacturing. The method further comprises, when the first set of security artifacts matches the second set of security artifacts, then verifying the computing device as trusted and permitting communication between the computing device and a secured computing environment, and when the first set of security artifacts does not match the second set of security artifacts, then not verifying the computing device as trusted and not permitting communication between the computing device and the secured computing environment.

The automated changeover of a transfer encryption key from one transfer encryption key to another. This occurs in an environment in which a set of computing systems are to share one or more keys (such as a private and public key pair). The transfer encryption key is used to encrypt communications of the key(s) such that the encrypted key(s) may be transferred over a transfer system without the transfer system having access to the key(s). In order to perform automated changeover of the transfer encryption key, one of the set of computing systems encrypts the next transfer encryption key with the prior transfer encryption key. The transfer system provides this encrypted message to the remainder of the set of computing systems, which may then decrypt the encrypted message using the prior transfer encryption key, to find the next transfer encryption key.
