Multi-party off-the-record messaging

Ian Goldberg, Berkant Ustaoğlu, Matthew D. Van Gundy, Hao Chen
2009 Proceedings of the 16th ACM conference on Computer and communications security - CCS '09  
We then propose a solution to multi-party off-the-record instant messaging that satisfies the above properties.  ...  Off-the-Record Messaging, proposed in 2004 by Borisov, Goldberg and Brewer, and its subsequent improvements, simulate private two-party meetings.  ...  We also thank the anonymous reviewers for their helpful comments.  ...

Performance trade-offs on a secure multi-party relational database

Rogério Pontes, Mário Pinto, Manuel Barbosa, Ricardo Vilaça, Miguel Matos, Rui Oliveira
2017 Proceedings of the Symposium on Applied Computing - SAC '17  
This issue has been tackled by multiple secure databases that provide trade-offs between security, query capabilities and performance.  ...  We propose a SQL database prototype capable of offering a trade-off between security and query latency by using a different secure protocol.  ...  Agreement, and through the European Regional Development Fund (ERDF).  ...

Off-the-Record Instant Messaging for Group Conversation

Jiang Bian, Remzi Seker, Umit Topaloglu
2007 2007 IEEE International Conference on Information Reuse and Integration  
Off-the-record (OTR) is a protocol which enables IM users to have private conversations over the open and insecure public Internet.  ...  This project implements an extension of the two-party OTR protocol, named Group OTR-GOTR.  ...  However, for an off-the-record IM system, some security features need to be reconsidered, particularly, non-repudiation.  ...

After that, it presents in more detail the 1-N multi-party non-repudiation solutions for distribution of different messages to multiple recipients.  ...  Finally it discusses the advanced solutions for two typical multi-party non-repudiation applications, i.e., multi-party certified email and multi-party contract signing. Evidence Transfer.  ...  On the other hand, this is the only one we can compare with as an off-line multi-party non-repudiation protocol.  ...

Contract signature in e-commerce

Lein Harn, Chu-Hsing Lin
2011 Computers & electrical engineering  
The contract signature scheme adopts a digital multi-signature scheme in public-key cryptography to facilitate fair signature exchange over network.  ...  In case any signer releases the partial signature to others, the signer does not bind to the contract.  ...  This multi-signature allows any number of signers to work together to generate a digital multi-signature corresponding to a message.  ...

Multicast address management and connection control based on hierarchical autonomous structure

Jian Wang, Fuyan Zhang
1999 Journal of Computer Science and Technology  
The paper also describes the normal operations of multicast address management and multi-point connections controller.  ...  Connection control hierarchy (CCH) based on master/slave relationship and a simple efficient building algorithm of multi-point connection is also built.  ...  These limitations hinder further development and deployment of multi-party applications, and unnecessarily move the burden of network management operations to the users.  ...
