On-Off Attack Definition

Thursday, March 21, 2019

On-Off Attack definition:“By behaving well and badly alternatively, the On-off attack aims to make the trust management scheme consider a bad behavior as a temporary error. Thus, the malicious node would remain active and would have more opportunities to attack the network. Moreover, there may be circumstances under which an On-off attacker should be allowed to re-main in the system. That is, if the cost of removing the at-tacker is higher than the cost that the attack imposes on the system, then it may be better to leave it alone.”Source: Trust Management for Defending On-Off Attacks
