Language based policy analysis in a SPKI Trust Management System

Arun K. Eamani, A. Prasad Sistla
2006 Journal of Computer Security  
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.  ...  While we give a logic to formulate policy analysis problems in the context of SPKI/SDSI we feel that full fledged languages for policy analysis in other distributed access control systems and trust management  ...

The Design and Implementation of Secure Event Manager Using SPKI/SDSI Certificate [chapter]

YoungLok Lee, HyungHyo Lee, Seungyong Lee, HeeMan Park, BongNam Noh
2005 Lecture Notes in Computer Science  
Accordingly, we design and implement the event manager based on Jini and suggest three methods in which only right event consumer can listen to the event using Access-Control Lists and SPKI/SDSI certificates  ...  In the proposed method, our event manager controls the access of events by putting trust checking engine on Jini.  ...  Event Management System Based on JavaSpace Jini [5] is a middleware in composing the home networking. The purpose of Jini is to accomplish "Network plug and Work".  ...

Security Mechanisms for Mobile Agent Platforms Based on SPKI/SDSI Chains of Trust [chapter]

Michelle S. Wangham, Joni da Silva Fraga, Rafael R. Obelheiro, Galeno A. Jung, Elizabeth Fernandes
2004 Lecture Notes in Computer Science  
This work defines a security scheme, based on SPKI/SDSI chains of trust, for protecting mobile agent platforms in large-scale distributed systems.  ...  Due to the flexibility of the SPKI/SDSI certificate delegation infrastructures used, the proposed scheme provides a decentralized control for authorization and authentication. 1 http://lia.deis.unibo.it  ...  Acknowledgments The authors thank the "IFM (Instituto Fábrica do Milênio)" and "Chains of Trust" project (CNPq 552175/01-3) members for their contributions.  ...

Distributed Policy Specification and Interpretation with Classified Advertisements [chapter]

Nicholas Coleman
2012 Lecture Notes in Computer Science  
In a distributed system, the principle of separation of policy and mechanism provides the flexibility to revise policies without altering mechanisms and vice versa.  ...  Techniques for policy analysis in the context of resource selection and authorization are also presented.  ...  We have demonstrated that the ClassAd language can be used to specify SPKI/SDSI authorization policies, and an enhanced gangmatching algorithm can be used to assemble SPKI/SDSI certificate chains correctly  ...

Distributed Trust [chapter]

John Ioannidis, Angelos Keromytis
2004 The Practical Handbook of Internet Computing  
If the processing plan presented in were universally adopted, then SPKI would be a trust-management engine.  ...  Other Trust-Based Systems The REFEREE system of Chu et al. [1997] is like PolicyMaker in that it supports full programmability of assertions (policies and credentials).  ...

Trust Management Languages and Complexity [chapter]

Krzysztof Sacha
2011 Lecture Notes in Computer Science  
This way, trust management languages are a tool for describing credentials and specifying access control policies in a flexible and modifiable way.  ...  This paper discusses the expressive power of trust management languages, describes a new extension to Role-based Trust Managements language RT T , and evaluates the complexity of algorithm that is used  ...  a single role expression, do not exist in RT T or any other Role based Trust management language.  ...

The Role of Trust Management in Distributed Systems Security [chapter]

Matt Blaze, Joan Feigenbaum, John Ioannidis, Angelos D. Keromytis
1999 Lecture Notes in Computer Science  
Trust-management engines avoid the need to resolve "identities" in an authorization decision. Instead, they express privileges and restrictions in a programming language.  ...  We also report on our experience using trust-management engines in several distributed-system applications. -Authentication: In an operating system, the identity of a principal is well known.  ...  Architectures based on a trust-management system can be easily extended if, in the future, it becomes necessary to base access decisions on more complex rules than are captured by an ACL.  ...

SAFE: A Declarative Trust Management System with Linked Credentials [article]

Vamsi Thummala, Jeff Chase
2015 arXiv   pre-print
We present SAFE, an integrated system for managing trust using a logic-based declarative language.  ...  Logical trust systems authorize each request by constructing a proof from a context---a set of authenticated logic statements representing credentials and policies issued by various principals in a networked  ...  Over time, the formal foundations of trust management systems have converged on logic-based declarative languages-trust logic.  ...

Delegation logic

Ninghui Li, Benjamin N. Grosof, Joan Feigenbaum
2003 ACM Transactions on Privacy and Security  
We adopt the trust-management approach, in which "authorization" is viewed as a "proof-of-compliance" problem: Does a set of credentials prove that a request complies with a policy?  ...  We develop a logic-based language, called Delegation Logic (DL), to represent policies, credentials, and requests in distributed authorization.  ...  Acknowledgement The first author is currently supported by DARPA through SPAWAR contracts N66001-00-C-8015 and by DoD MURI "Semantics Consistency in Information Exchange" as ONR Grant N00014-97-1-0505.  ...

2005 ACM Transactions on Privacy and Security  
We address these issues in our design of a distributed access control mechanism for a people location system.  ...  To show feasibility of our design, we built an example implementation based on SPKI/SDSI certificates.
