1. MQTT is a lightweight publish/subscribe messaging protocol that was co-invented by IBM over 13 years ago for use in remote sensors and devices with low-bandwidth and intermittent connections. 2. It uses a publish/subscribe model where senders of messages, called publishers, do not program the messages for specific receivers, called subscribers, but instead categorize published messages into topics. Subscribers receive messages that were published to topics they expressed interest in. 3. MQTT is well-suited for constrained devices and Internet of Things applications because it minimizes network bandwidth and device resource usage while still providing reliable delivery of messages.

Mqtt overview (iot)

David Fowler

MQTT is a lightweight publish/subscribe messaging protocol ideal for constrained devices and low-bandwidth networks. It allows devices to publish messages to topics and subscribe to receive messages for topics, minimizing network usage. MQTT was created in 1999 and is in the process of being standardized. It uses TCP ports 1883 and 8883 and supports publish/subscribe messaging along with quality of service (QoS) guarantees and message retention. MQTT brokers allow clients like IoT devices to connect and publish/subscribe to topics to send and receive payload data.

Message queuing telemetry transport (mqtt)

Hamdamboy

MQTT is a publish-subscribe messaging protocol that allows devices to connect to a broker server and publish or subscribe to topics. It has three main parts: a broker server that accepts subscribers and retransmits messages from publishers, subscriber clients that listen for incoming messages, and publisher clients that can produce information to notify others. MQTT uses TCP/IP and a publisher-broker-subscriber pattern to allow one publisher to multicast messages to many subscribers through topics. It supports different levels of quality of service (QoS) to control message delivery reliability.

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
