University of California, Los Angeles (UCLA)


Welcome to the Internet Research Laboratory (IRL), part of the Computer Science department at the University of California, Los Angeles (UCLA). The IRL's research primarily focuses on Named Data Networking. Previously, our research covered fault tolerance in large scale distributed systems, Internet routing infrastructure, inter-domain routing (namely, BGP), and protocol design principles for large-scale, self-organizing systems. Our group has produced numerous publications over the years.

The Internet Research Laboratory is headed by Prof. Lixia Zhang.

Paper Reading: Decentralized Trust Management

We recently read the Paper ‘Decentralized Trust Management’ by Matt Blaze, Joan Feigenbaum, and Jack Lacy. To begin with a (very abridged and approximate) summary of the paper itself: the paper was written in 1996, and is primarily concerned with making the argument that not only were then-current trust management systems (PGP, X.509) insufficient/poorly matched to the task of managing trust, but also that a better option would be to have the trust management credential (e.g. the certificate) hold all the information about whether or not an action can be taken. This in turn leads directly to authorization (or lack thereof). To this end, the paper outlined the PolicyMaker system, which implements the aforementioned option. To applications, the system appears to be a query engine on top of a database. The queries are of the form key1, key2, … keyn REQUESTS ActionString. If the ActionString matches some filter (which, to a good approximation, can be either regular expressions or AWK programs) that was set up in PolicyMaker. In this way, PolicyMaker can authenticate requests like ‘Bill for < $500 from Janice’.
