....with that information would have been handled. The term mobile user will be used to refer to the intended user of the concerned mobile computer. In this paper we assume that an object oriented federated database is used, because the reported work forms part of a larger research project see [12, 13, 15, 14]. We assume that objects have been translated to some internal representation that includes the representation of methods and data see [15] for details. See [9] for a description of objectoriented databases and [10, 11, 17] for a discussion of security in such databases. A federated database is ....

....from THATSITE, THATSITE had to log the terminal number where the message was initiated and the SIB at that site can simply return it. If the message did not originate from that site, that site will not know the terminal number and return a not known which will cause the access to be denied. See [7, 8] for a discussion of the complexities and possibilities surrounding local and global security 13 information. For SPOP we assume that the only global security information is the time and the current message sensitivity. Further, we assume that the identification of the user who initiated a ....
....can record information about local users, messages that originate from their site and information about the site itself and use such values in their extended access checking. In addition, any similar information that may be obtained from other sites by mutual agreement, may also be used see [7, 8]. The clearance level and current sensitivity level of the message may also be used. Note that the request from the TCC to the TLE does imply that information flows from a TCC to a TLE not necessarily trusted by it. However, as argued in [7] this does not constitute a security risk. The SIB ....
