Abstract:
A cryptographic key for a client is generated at a server. The cryptographic key has a key identification and a corresponding key value. The key identification and the corresponding key value are presented to the client. A query of a portion less than the key value for the client is generated after the key identification and the corresponding key value are presented to the client. Entries from the client are received in response to the query. The cryptographic key is activated after the entries are validated.
