Arm buys Offspark to increase IoT security

Cambridge-basedArm has signalled the importance of security in IoT with the acquisition of Offspark, an IoT security software company. Offspark, a Dutch company, specialises in IoT communications security and its Polar SSL technology is already deployed in a wide variety of devices including sensor modules, communications modules and smartphones.
As security is a requirement for all IoT deployments, this will help developers using the Arm Mbed platform to design and build IoT products with communications security and software cryptography.
Polar SSL is the IoT industry's most pervasive embedded transport layer security (TLS) method. It will form the core of the Arm Mbed communications security and software cryptography strategy and will be rebranded as Mbed TLS. The technology will remain open source and will be made available to developers for commercial use.
"We have always said that security must be the foundation of any IoT system and the acquisition of Offspark is evidence of us making that happen," said Krisztian Flautner, general manager for IoT business at Arm. "Polar SSL technology is already deployed by the leading IoT players. The fact that those same companies also utilise Arm Cortex processor and software technologies means we are now able to provide a complete bedrock solution for the industry to innovate from."
Mbed TLS will be available for standalone use and as part of Mbed OS, providing support for TLS and DTLS optimised for embedded devices and complementing the Cryptobox technology of Mbed OS that enables secure execution and storage. Mbed TLS not only targets embedded devices but will continue to expand with features for the non-embedded arena. Arm will release Mbed OS under an Apache 2.0 licence, which will include Mbed TLS, Thread and other technologies toward the end of 2015.
"Arm is undeniably the front-runner in the embedded world and combining with them is the perfect way of scaling our business," said Paul Bakker, CEO of Offspark. "Security is the most fundamental aspect in ensuring people trust IoT technology and that is only possible with a truly tailored solution. Together, Arm and Offspark can provide security to the edge of any system and we look forward to working with our partners to help them deliver some exciting new projects."
The release of Mbed TLS 1.3.10 is now available under GPL and to existing Polar SSL customers.
