Abstract:
1. A method of accessing a recovery key to decrypt confidential data of a device, the method comprising: storing a private key and an associated access control list on a set of servers, the access control list storing a hash value of executable code running on the set of servers at a time of generating the private key; receiving a request at the set of servers to access the recovery key, the request comprising a secure object comprising the recovery key, the secure object encrypted with a public key corresponding to said private key; and decrypting the secure object using the private key to access the secure object comprising the recovery key, the private key accessible only when a hash value of the executable code running on the set of servers at a time of accessing the private key matches the hash of the executable code running on the set of servers at the time of generating the private key.
