Abstract
A computer and method for managing a shared key in a cluster of computers utilizes a node key to decrypt an encrypted shared key to obtain the shared key. A computer in the cluster can receive the node key from another computer in the cluster by transmitting an encrypted node key that has been encrypted using a master key to the other computer in the cluster, which is then decrypted using the master key at the other computer. The received node key can then be used by the requesting computer to decrypt the encrypted shared key to obtain the shared key.
