General Adversary Structures in Byzantine Agreement and Multi-Party Computation with Active and Omission Corruption

ePrint Report: General Adversary Structures in Byzantine Agreement and Multi-Party Computation with Active and Omission Corruption

Konstantinos Brazitikos, Vassilis Zikas

Typical results in multi-party computation (in short, MPC) capture faulty parties by assuming a threshold adversary corrupting parties actively and/or fail-corrupting. These corruption types are, however, inadequate for capturing correct parties that might suffer temporary network failures and/or localized faults - these are particularly relevant for MPC over large, global scale networks. Omission faults and general adversary structures have been …
