Establishing initial trust in autonomous Delay Tolerant Networks without centralised PKI

C.I. Djamaludin, E. Foo, P. Corke
2013 Computers & security  
A Delay Tolerant Network (DTN) is one where nodes can be highly mobile, with long message delay times forming dynamic and fragmented networks.  ...  In this paper, we utilise a key distribution model based on the Web of Trust principle, and employ a simple leverage of common friends trust system to establish initial trust in autonomous DTN's.  ...  DTN networks without a centralised PKI (Seth and Keshav, 2005) have employed identity based cryptography.  ...

Cryptographic Key Management in Delay Tolerant Networks: A Survey

Sofia Anna Menesidou, Vasilios Katos, Georgios Kambourakis
2017 Future Internet  
Since their appearance at the dawn of the second millennium, Delay or Disruption Tolerant Networks (DTNs) have gradually evolved, spurring the development of a variety of methods and protocols for making  ...  Towards this goal, we have grouped the surveyed key management methods into three major categories depending on whether the particular method copes with (a) security initialization, (b) key establishment  ...  This is based on a DTN without a centralised PKI that ensures entity authentication and utilises the LCF trust system presented in [33] .  ...

SOMA: Self-Organised Mesh Authentication [chapter]

Foivos F. Demertzis, Christos Xenakis
2011 Lecture Notes in Computer Science  
Our goal is to create a large-scale authentication system for mesh networks without the need of a Trusted Third Party.  ...  Community mesh networks have emerged rapidly in every metropolis around the world, however many of the security methods applied are counter-intuitive and usually disrupt the autonomous characteristics  ...  This introduces a delay in the initial stages of network and can cause problems when there are insufficient trust relationships.  ...

A First Look at Identity Management Schemes on the Blockchain [article]

Paul Dunphy, Fabien A.P. Petitcolas
2018 arXiv   pre-print
These new approaches to identity management (IdM) propose to enhance decentralisation, transparency and user control in transactions that involve identity information; but, given the historical challenge  ...  Although there are no trusted third parties in the PKI-sense on Sovrin, users must rely on agencies that will act on their behalf on the Sovrin network and on the stewards maintaining the ledger.  ...  However, due to the lack of a central authority, trust of these attributes currently relies upon ad-hoc trust establishment between organisations.  ...

Secure Inter-Domain Routing Based on Blockchain: A Comprehensive Survey

Lukas Mastilak, Pavol Helebrandt, Marek Galinski, Ivan Kotuliak
2022 Sensors  
The BGP plays a significant role in routing, but its behaviour is essentially naive, trusting neighbours without authenticating advertised IP prefixes.  ...  The whole Internet consists of thousands of autonomous systems that transfer data with one another.  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results.  ...

GDPR-Compliant Personal Data Management: A Blockchain-based Solution

Nguyen Binh Truong, Kai Sun, Gyu Myoung Lee, Yike Guo
2019 IEEE Transactions on Information Forensics and Security  
By honestly participating in the platform, a service provider can be endorsed by the blockchain network that it is fully GDPR-compliant; otherwise, any violation is immutably recorded and is easily figured  ...  The platform enables data owners to impose data usage consent, ensures only designated parties can process personal data, and logs all data activities in an immutable distributed ledger using smart contract  ...  This solution approach is designed under a centralised client-server mindset that imposes unsolvable challenges in complying with the new GDPR requirements and in establishing trust with clients [14]  ...
