Chip designer ARM announced today it has bought Offspark, a company specializing in security software for the Internet of Things.
Back in November it was announced that ARM had acquired PolarSSL, Offspark’s version of the SSL encryption standard that many websites use to establish secure communication. That software has been rebranded as mbed TLS and will become part of ARM’s mbed platform for IoT development.
mbed TLS will be integrated with mbed OS, an operating system for ARM’s Cortex-M chips that end up in many IoT products. It will also continue to be available as standalone software for developers to use as they see fit. As PolarSSL, it has so far been distributed under both the GPL open-source license and a commercial license; later this year mbed TLS will switch to the Apache license to simplify the situation while still allowing both open- and close-source implementations.
By bringing Offspark fully under its own roof, ARM is trying to send a message about its commitment to IoT security. “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, ARM’s general manager for IoT business, in a statement.
You might say that ARM is putting an indeterminate amount of money where its mouth is: Terms of the acquisition were not disclosed.
