The certificate of an attacker is revoked on the basis of votes from its neighbors. In URSA, each node performs one-hop monitoring, and exchanges monitoring information with its neighboring nodes. When the Star Student Project number of negative votes exceeds a predetermined number, the certificate of the accused node will be revoked. Since nodes cannot communicate with others without valid certificates, revoking the certificate of a voted node implies isolation of that node from network activities.
