Reducing the Dependence of SPKI/SDSI on PKI
Trust-management systems address the authorization problem in distributed systems. They offer several advantages over other approaches, such as support for delegation and making authorization decisions in a decentralized manner. Nonetheless, trust-management systems such as KeyNote and SPKI/SDSI have seen limited deployment in the real world. One reason for this is that both systems require a p...
متن کاملReducing the Dependence of Trust-Management Systems on PKI
Trust-management systems address the authorization problem in distributed systems by defining a formal language for expressing authorization and access-control policies, and relying on an algorithm to determine when a specific request can be granted. For authorization in distributed systems, trustmanagement systems offer several advantages over other approaches, such as support for delegation a...
متن کاملGGRA: a grouped gossip-based reputation aggregation algorithm
An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...
متن کاملLanguage based policy analysis in a SPKI Trust Management System
SPKI/SDSI is a standard for issuing authorization and name certificates. SPKI/SDSI can be used to implement a Trust Management System, where the policy for resource access is distributively specified by multiple trusted entities. Agents in the system need a formal mechanism for understanding the current state of policy. We present a first order temporal logic, called FTPL for specifying propert...
متن کاملDistributed SPKI/SDSI-Based Security for Networks of Devices
We describe a distributed security system based on SPKI/SDSI (Simple Public-Key Infrastructure/Simple Distributed Security Infrastructure) for heterogeneously networked, diverse devices. All components of the system, for example, appliances, wearable gadgets, software agents, and users have associated trusted software proxies that either run on the appliance hardware or on a trusted computer. W...
