Abstract
A method, a system, an apparatus, and a computer program product are presented for an authentication process. A host application or system within a distributed data processing system supports one or more controlled resources, such as a legacy application, that requires the receipt of authentication data prior to allowing a user to have access to the controlled resource. The required authentication data is encrypted using the public key of the host system, and an attribute certificate containing the encrypted authentication data is generated by an attribute-certificate-issuing authority. When a user of a client application or system requires access to the controlled resource, the attribute certificate is sent to the host, which decrypts the authentication data with its private key prior to forwarding the authentication data to the controlled resource. The controlled resource then authenticates a user based on the provided authentication data.
