ARM builds fortress against IoT hackers via Israel acquisition
Cambridge superchip designer, ARM Holdings, has acquired Israeli business Sansa Security to fortify the defence of IoT technology against cyber attacks.
Sansa’s expertise currently enables security in more than 150 million products a year with its technology deployed across a range of smart connected devices and enterprise systems. ARM isn’t revealing how much it is paying for Sansa but chief technology officer, Mike Muller, spelled out the power of the deal.
The deal complements the ARM security portfolio, including ARM TrustZone technology and SecurCore processor IP, as Muller explained: “Any connected device could be a target for a malicious attack so we must embed security at every potential attack point. Protection against hackers works best when it is multi-layered, so we are extending our security technology capability into hardware subsystems and trusted software. This means our partners will be able to license a comprehensive security suite from a single source.”
He said Sansa technology makes it easier for manufacturers to build secure products by offering a complete hardware subsystem that adds additional isolation of security operations from the main application processor. This is complemented by software components operating on top of trusted execution environments to perform security-sensitive operations.
The acquisition builds on ARM’s embedded TrustZone technology, creating extra protection against malware and malicious software.
It is a system-wide approach that underpins security-related chipset and trusted software needs. This enables the protection of any connected device and management of sensitive data and content.
Coby Sella, CEO of Sansa Security said: “Our technology is already being used to protect data gathered and transmitted by a multitude of IoT and mobile devices. Joining ARM will enable us to scale the business by helping ARM’s global technology partners address their most pressing security needs. Aligning what we do with the world’s leading IP company allows us to develop our products and capability to new levels.”
