FPR_UNL.1     Unlinkability

User application notes

This component ensures that users cannot link different operations in the system and thereby obtain information.

Operations

Assignment:

In FPR_UNL.1.1 the PP/ST author should specify the set of users and/ or subjects against which the TSF must provide protection. For example, even if the PP/ST author specifies a single user or subject role, the TSF must not only provide protection against each individual user or subject, but must protect with respect to cooperating users and/or subjects. A set of users, for example, could be a group of users which can operate under the same role or can all use the same process(es).

In FPR_UNL.1.1 the PP/ST author should identify the list of operations which should be subjected to the unlinkability requirement, for example, "sending email".

Selection:

In FPR_UNL.1.1 the PP/ST author should select the relationships that should be obscured. The selection allows either the user identity or an assignment of relations to be specified.

Assignment:

In FPR_UNL.1.1 the PP/ST author should identify the list of relations which should be protected against, for example, "originate from the same terminal".
