Threshold RSA for Dynamic and Ad-Hoc Groups [chapter]

Rosario Gennaro, Shai Halevi, Hugo Krawczyk, Tal Rabin
Advances in Cryptology – EUROCRYPT 2008  
We consider the use of threshold signatures in ad-hoc and dynamic groups such as MANETs ("mobile ad-hoc networks").  ...  The resultant schemes provide the efficiency and flexibility needed in ad-hoc groups, and add the capability of incorporating new members (share-holders) to the group of potential signers without relying  ...  We are grateful to Stas Jarecki and the anonymous Eurocrypt reviewers for their helpful comments.  ...

Ad hoc key management infrastructure

B. Lehane, L. Dolye, D. O'Mahony
2005 International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II  
Key Management Infrastructure in an ad hoc network needs to be formed in an ad hoc manner.  ...  A further application to group keying with distributed group membership management is also discussed.  ...  Because of the potentially highly dynamic nature of groups in ad hoc networks, it is preferable to have such a distributed scheme that allows a rapid response time to group changes.  ...

Dynamic Threshold Cryptosystem without Group Manager

Andreas Noack, Stefan Spitz
2009 Network Protocols and Algorithms  
Dynamic threshold cryptosystems are best suited to realize distributed signatures in dynamic (e.g. ad-hoc) networks.  ...  In dynamic networks with flexible memberships, group signatures and distributed signatures are an important problem.  ...  This is an important feature for dynamic groups, since it is very common, e.g. in ad-hoc networks that members leave a group. Gennaro et al. used RSA and bi-variate polynomials for their scheme.  ...

Admission control in Peer-to-Peer

Nitesh Saxena, Gene Tsudik, Jeong Hyun Yi
2003 Proceedings of the 1st ACM workshop on Security of ad hoc and sensor networks - SASN '03  
Among other things, our experimental results demonstrate that, unfortunately, advanced cryptographic constructs (such as verifiable threshold signatures) are not yet ready for prime time.  ...  This paper builds upon some recent work [11] which constructed a peer group admission control framework based on different policies and corresponding cryptographic techniques.  ...  For large groups and especially for dynamic thresholds, the GMC will become huge for the PS schemes.  ...

An Approach for Secure Mobile Ad Hoc Networks: Key Management and Routing

Hridya V Deva raj, Jinu Mohan
2016 International Journal of Innovative Research in Computer and Communication Engineering  
Because of this infrastructure less environment, limited power and dynamic topology, it becomes very difficult to provide a secure environment in MANET.  ...  Reason for this increased attention is the wide range of multimedia applications running in the infrastructure less environment.  ...  However, group key management for large and dynamic groups in MANETs is a difficult problem because of the requirement of scalability and security.Thus this phase proposes a reliable dynamic clustering  ...
