ABSTRACT:
A method and apparatus for unique and secure identification of a computing service node. The service node is coupled to an administrative node and to a certificate authority node via a computer network. The administrative and certificate authority nodes have respective public and private keys. A shared key is established between the certificate authority node and the administrative node, and while booting the service node, the service node generates its public key and private key. The administrative node double encrypts a selected value, first using the shared key and second using the public key of the service node, whereby a double encrypted value is generated. The double encrypted value is decrypted at the service node, whereby a single encrypted value is generated. Whether the certificate authority node is able to successfully decrypt the single encrypted value using the shared key determines whether the administrative node is authentic.
