Subject Switching Algorithms for Access Control in Federated Databases
[chapter]
2002
Database and Application Security XV
Preserved Fulltext
Authentication in federated database systems present difficulties because the autonomously operated components may not know the identity of federation users. ...
One proposed solution is subject switching, where the federation translates the federated users identity to that of an agreed upon component subject. ...
Section 3 presents the concept of and algorithms for subject switching. It further shows why subject switching is not always possible. ...

We point out several problems in applying existing access control schemes and give our solutions. ...
First we show a logical architecture of XML federations, which is adapted from the common architecture of traditional federated databases according to the unique requirements of XML federations. ...
Access control for XML documents is based on authorization rules consisting of subject, object, action, access, and other extensions. ...
