Broadcast from Minicast Secure Against General Adversaries [chapter]

Pavel Raykov
2015 Lecture Notes in Computer Science  
In this paper we combine both generalizations by considering the problem of achieving broadcast from b-minicast channels secure against general adversaries.  ...  It has been shown that broadcast secure against adversaries corrupting up to t parties is achievable from b-minicast if and only if t < b−1 b+1 n.  ...  To show (1) we construct a protocol that realizes broadcast from minicast and is secure against general adversaries.  ...

2019 International Symposium on Distributed Computing  
Fitzi and Maurer [2] consider a (non-threshold) general adversary that is characterized by the subsets of parties that could be corrupted, and show that broadcast can be realized from bilateral channels  ...  These generalizations are unified in the work by Raykov [5], where a tight condition on the possible corrupted sets such that broadcast is achievable from a complete set of b-minicasts is shown.  ...  Essential Partial Broadcasts. We identify some types of b-minicast channels that are essential for secure broadcast to be possible against general adversaries.  ...
