Alessandro Sorniotti, Refik Molva
2010 Proceedings of the 2010 ACM Symposium on Applied Computing - SAC '10  
In this paper we present the first framework that allows the creation of Secret Interest Groups (SIGs) in Online Social Networks; SIGs are self managed groups formed outside of the social network, around  ...  secret, sensitive or private topics.  ...  First, we use mechanisms for Secret Sharing and Secret Redistributions to allow SIG managers to share a secret and perform joint computations.  ...

Mobile Agents: Preserving Privacy and Anonymity [chapter]

Aneta Zwierko, Zbigniew Kotulski
2005 Lecture Notes in Computer Science  
The proposed schemes are based on different cryptographic primitives: a secret-sharing scheme and a zerokonwledge proof.  ...  In our proposal the Asmuth and Bloom secure secret sharing scheme ( [4] ) is used.  ...  He computes the secret (denoted as k): k ≡ s (mod p 0 ) and shares: s i ≡ s (mod p i ). The shares are distributed to participants via secure channel.  ...
