Suicide for the Common Good: a New Strategy for Credential Revocation in Self-Organizing Systems

摘要

We consider the problem of credential revocation in self-organizing systems. In the absence of a common trusted authority, reaching a decision is slow, expensive and prone to manipulation. We propose a radical, new strategy-suicide for the common good- which drastically simplifies the decision-making process and revocation orders. Our mechanism is fully decentralized, incurs low communication and storage overhead, enables fast removal of misbehaving nodes, and is ideally suited to highly mobile networks.
