British semiconductor and software design company ARM has acquired Israel-based Sansa Security, a component provider for Internet of Things devices, to increase the capability of ARM’s security portfolio.

ARM’s recent acquisition will provide hardware security IP and software for advanced system-on-chip components deployed in Internet of Things and mobile devices.

The Cambridge-based company currently enables security in more than 150 million products a year and Sansa Security technology is deployed across a range of smart connected devices and enterprise systems.

The deal complements the ARM security portfolio, including ARM TrustZone technology and SecurCore processor IP.

According to BusinessWire, the acquisition will “offer hardware and software-based security features, boosting protection for sensitive data and content on any connected device.”

Internet of Things security

Sansa Security offers a hardware subsystem that adds additional isolation of security operations from the main application processor.

The hardware subsystem is complemented by software components to perform security-sensitive operations. The acquisition builds upon ARM’s embedded TrustZone technology, to provide extra protection against malware and malicious software.

ARM TrustZone technology is a system-wide approach to security for client and server computing platforms, including handsets, tablets, wearable devices and enterprise systems.

The system-wide approach enables the protection of any connected device and management of sensitive data and content.

Mike Muller, CTO at ARM, said: “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.”
