Secure Hybrid Publish-Subscribe Messaging Architecture

In many applications of the Internet of Things (IoT) and Machine to machine (M2M) communications, maintaining low latency is an important performance indicator. Encryption protocols are known to be CPU intensive, affecting the dissipated power and increasing the latency. Therefore, the security is often neglected in order to speed up, in particular, the realtime applications that require prompt response. However, in advanced communication...
