Abstract:
The notion of decentralized trust management (DTM) was coined by Blaze, Feigenbaum, and Lacy in 1996 to describe a collection of desiderata for decentralized authorization systems. Since then, the concept has been subject of intensively research, as testified by a number of yearly workshops and conferences on the topic.
In this talk we introduce role-based decentralized trust management systems and  we exemplify their essential features by summarizing one specific attribute-based decentralized trust management framework: RT, introduced by Li, Mitchell and Winsborough.
