Abstract
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.
