ABSTRACT:
Provided are techniques for key generation and retrieval. Unique identifiers of two or more key servers are stored, wherein each key server is capable of generating keys for encryption of data and of returning keys for decryption of data. A key request is received. A technique for selecting one of the key servers to which the key request is to be forwarded is identified. One of the key servers is selected using the identified technique. The key request is sent to the identified key server.
