Soner Sevinc will present his research seminar/general exam on Friday May 16 
at 10AM in Room 402.  The members of his committee are:  Larry Peterson (advisor), 
Jennifer Rexford, and Ed Felten.  Everyone is invited to attend his talk and those 
faculty wishing to remain for the oral exam following are welcome to do so.  His 
abstract and reading list follow below.

Large-scale network systems often must support users from multiple organizations that want
to use resources owned by other organizations. Managing resources in such an environment
must, therefore, be decentralized. 
Such  systems require unique, immutable and verifiable naming of entities, and a security
architecture that includes a fine grained authorization. Verification should allow
multiple levels of trust to make the security system decentralized. Fail safety is
necessary for correct operation of such a large system, limiting the damage a malicious or
mis-operating entity can have to a short period of time. 
PlanetLab being one of such systems is in the stage of decentralization with federation
with other similar systems or separating into several autonomous pieces. PlanetLab's
current identity based authorization architecture makes decentralization difficult. The
features of a more manageable system should include making the sources of authorization
explicit, separating identity from rights, and allowing delegation of those rights. The
protocols used within the system should support secure communication, possibly leveraging
existing security schemes. 
My talk describes an architecture developed in the context of PlanetLab. The design
includes a naming system, support for decentralized trust, and a fine-grained
authorization mechanism. I will also describe a prototype implementation that leverages
PlanetLab. "
