The Pleasure of Gossip

چکیده
Rohit Parikh has written on levels of knowledge [PK92]. Levels of knowledge are relevant for the analysis of gossip protocols. Gossip protocols describe the dissemination of information over a network. We present some examples of epistemic gossip protocols, wherein the agents or processes communicate with each other by peer-to-peer contact (telephone calls), as in the usal gossip protocols, but wherein the decision to contact another agent is based on the calling agent’s information only. This is, as far as we know, unusual in gossip protocols. In this we wish to honour Rohit Parikh’s long career and many contributions to logic and computer science. ∗Hans van Ditmarsch is corresponding author. We thank a reviewer for insightful comments. Hans is also affiliated to IMSc, Chennai, as research associate, and he acknowledges support from ERC project EPS 313360. †To appear in: C. Başkent, L. Moss and R.

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...
