Establishing initial trust in autonomous Delay Tolerant Networks without centralised PKI
2013
Computers & security
Preserved Fulltext
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. ...

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] . ...

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. ...

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. ...
