Mitigating delay attacks on Constrained Application Protocol
Jintao Zhu, Yan Liu · 2017
Various attacks including delay attacks have become a topic in the security of Internet of Things (IoT) especially for the constrained nodes utilizing sensors and actuators which connect and interact with the physical world. [I-D.mattsson-core-coap-actuators] describes several serious delay attacks, discusses tougher requirements and then recommends mechanisms to mitigate the attacks. It also specifies some disadvantages with the mechanisms. This document proposes alternative mechanisms that address some of the disadvantages
