ARM has purchased Internet of Things (IoT) security company Offspark to provide developers with a secure platform to design and create products.
The UK mobile chipmaker's mbed platform is a combination of operating system, device server and developer tools designed to provide a foundation for the creation of IoT devices.
ARM will now have access to Offspark's PolarSSL, an IoT security layer used in devices such as smartphones, sensors and communication modules.
The Transport Layer Security (TLS) technology will be integrated into ARM's mbed platform. PolarSSL will be rebranded as ARM mbed TLS.
Paul Bakker, Offspark's founder, said that mbed TLS will provide secure communication and cryptography to the rest of the mbed products.
"Although the mbed ecosystem is primarily targeted at the world of the IoT, this does not mean that from now on mbed TLS will only work on ARM chipsets or IoT devices," he wrote on ARM's Connected Community forum.
"Mbed TLS will continue on the existing path and stay available and operate on regular embedded and non-embedded systems, just like PolarSSL today."
Krisztian Flautner, general manager of ARM's IoT business arm, said that security "must be the foundation of any IoT system", citing the acquisition of Offspark as an example ARM practising what it preaches.
Details of the acquisition are scarce. Offspark's website simply states: "There is nothing to find here anymore. Offspark is now part of ARM."
Bakker said that joining forces with ARM will give Offspark "invaluable support" in expanding the PolarSSL library.
"ARM's expansive and established ecosystem will give us the ability to expand PolarSSL technology to new partners," he said on Offspark's PolarSSL blog.
Bakker also hinted at "some exciting plans for 2015" and encouraged interested parties to await more announcements.
ARM is not the only chipmaker acquiring smaller companies to further develop its IoT platform. Intel recently acquired Lantiq to push the IoT connected home.
These acquisitions will give the companies more scope to offer complete IoT systems, despite the IoT facing fragmentation as the market expands.
