In this paper we propose and evaluate a new version of the CCM mode of operation, CCM-R, which is an extended and alternate version of the original CBC-MAC with Counter Mode(CCM) that was created to address the problem of counter synchronization.While CCM is considered secure when used/implemented correctly, it is still vulnerable to Denial of Service (DoS) attacks where packages in the stream are removed or modified with the purpose of destabilizing the synchronization of the counter states.Another possible way it can be destabilised is through random loss of packets due to noise or weak signals on wireless link.Therefore, in order to solve this problem, we have proposed a solution where we have embedded a secure counter synchronization approach into the original CCM mode of operation.The approach makes it immune to package loss and DoS attacks.The overhead is also kept at a minimum, making it suitable for low-power wireless IoT devices.
