Two Advancements in Standards: Open Trust Protocol and MQTT
A consortium of organizations, led by semiconductor design company ARM and digital security provider Symantec, have developed a draft security protocol designed to protect IoT devices. Known as The Open Trust Protocol (OTrP), it is designed as a decentralized approach to managing data and programming code securely, similarly to how e-commerce and banking security systems are designed. Its purpose is to protect IoT devices from attack via malware.

The protocol employs a public key infrastructure and is designed to be used in a Trusted Execution Environment, which is a secured segment of a smartphone or other connected device's processor, or with any microcontroller that can run RSA cryptography. The group has made the draft standard available for download at the Internet Engineering Task Force (IETF) website, so that developers can test it and create prototypical applications using the protocol. The IETF is a network of designers, operators, vendors and researchers who collaborate on the internet's architecture and operation.

The draft will remain on the IETF website until early next year, during which the IETF community will be invited to provide feedback. The consortium hopes to develop the protocol into an open, industry-wide data security standard.

In addition, the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) this week approved the messaging protocol MQTT, which was developed by the nonprofit IT standard development group Oasis, for standardization. Version 3.1.1 of MQTT was balloted through the Joint Technical Committee on Information Technology (JTC1) of ISO and IEC, and was given the designation ISO/IEC 20922.

MQTT is a publish/subscribe messaging transport protocol that requires little bandwidth, making it attractive for IoT applications in which sensors run on battery power. It is used, for example, in wireless blood-pressure monitors and other bio-medical devices, as well as for sensors that transmit data from oil and gas pipelines. According to Oasis, developers of connected-vehicle and mobile-phone applications are also beginning to use MQTT.
