Bionic Buffalo Tech Note #56
Security:
Unrestricted
•
A pre-authorization mechanism is provided. A customer will access a “trial” object to establish
whether or not authorization is likely to succeed at the time of use. The trial object also can serve
as a surrogate for the
Asset
in case the
Asset
itself does not support common security
mechanisms.
•
A value type,
AssetUseCriteria
, is defined, with methods to determine usage constraints to
be enforced by the broker. A consignment includes a sequence of
AssetUseCriteria
. Each
AssetTag
includes a sequence of zero or more criteria indices, each member of which refers to
one of the
AssetUseCriteria
. A broker is expected to employ the methods of the
AssetUseCriteria
to enforce the policies they incorporate. Details of this mechanism are
beyond the scope of this Tech Note; the salient point is that owners may establish usage policies,
and expect them to be enforced by the brokers. The scope of the policies may extend beyond
security to include other constraints.
Details of these AAM security mechanisms are beyond the scope of this Tech Note. For more
information, consult the AAM Technical Manual (Luxembourg).
