    Hi folks, Tuesday (21 October
    2003)

    Below are complete rewrite replacements for the former sections:

    - 5.4 Security
    - 6.1 Print Service Discovery Requirements

    Note that at our face-to-face review two weeks ago, we decided to
    DELETE
    entirely the former sections:

    - 5.5 Accounting Metrics - to be DELETED
    - 6 Other Considerations - to be DELETED

    Thus, the two replacement sections now are:

    - 5.4 Security
    - 5.5 Discovery

    Cheers,

    5.4 Security

    The PSI shall select one or more existing standard end-to-end security
    protocols. The selected PSI security protocol(s) shall be specified as
    optional to use for all PSI implementations, but mandatory to support
    for all PSI implementations. The selected PSI security protocol(s)
    shall support:

    (1) Client Authentication - protection from PSI service access by any
        unauthenticated client system or process.

    (2) Server Authentication - protection from PSI service offering by any
        unauthenticated server system or process.

    (3) Data Integrity - protection from PSI message insertion, message
        deletion, or message modification by any intermediate system.

    (4) Data Privacy - protection from PSI message content disclosure to
        any intermediate system.

    The PSI shall NOT specify or encourage the use of any hop-by-hop (link
    or network layer) security protocols, because they do not offer any
    end-to-end (application, session, or transport layer) security.

    5.5 Discovery

    The PSI should select and recommend one or more existing standard
    discovery protocols. The selected PSI disovery protocol(s) should
    support:

    (1) Service advertising

    (2) Service type discovery

    (3) Service capabilities discovery

    (4) Device advertising

    (5) Device type discovery

    (6) Device capabilities discovery
