  • receiving a digital certificate from the client at a host within the distributed data processing system;

    obtaining a host identity for the client from the digital certificate, wherein the host identity for the client identifies the client to the host, and wherein the host is not a certifying authority that issued the digital certificate;

    retrieving host-decryptable secret data associated with the host identity from the digital certificate;

    decrypting the host-decryptable secret data with a host private key to generate secret data; and

    authenticating the client at the host using the host identity and the secret data.
