Trusted Execution Environment

The new company will create what officials are calling a Trusted Execution Environment (TEE) based on ARM€™s TrustZone security product. The TEE will use both hardware security technology and industry-standard software interfaces, including interfaces from the GlobalPlatform industry association, the officials said. Devices with a TEE will offer consumers a device that will give them greater sense of security when performing transactions on the Internet, such as making mobile payments, banking and running work applications, they said.

"ARM integrates its TrustZone architecture into every ARM Cortex-A family processor to help our silicon partners deliver the deepest level of security in their hardware,€ ARM€™s Cade said in a statement. €œThe new venture will combine the security operations from three leading organizations. This will provide a trusted software environment capable of utilizing security from the hardware level up, in a consistent, open and accessible manner.€

The joint venture is only the latest proof point of the pending competition between Intel and ARM, as each looks to expand their reach into markets now dominated by the other. Intel is looking to become a significant player in the booming mobile computing space, while ARM and its manufacturing partners intend to bring their high-performance, low-power chip technology into PCs and low-power servers.

Security continues to be a key issue for mobile device users. During the Intel Developer Forum in September 2011, Intel and McAfee introduced DeepSAFE, a hardware-software platform aimed at preventing security and data breaches, block intrusions and stop malicious software from being installed on a device.

With DeepSAFE, the McAfee Endpoint Protection software hooks onto a chip€™s security features, providing a deeper security footprint and allowing the software to gain visibility into malware that operates before the operating system, according to Intel. Some of this malware can be difficult to detect.

DeepSAFE was the first indication of how Intel officials plan to incorporate McAfee security capabilities into their processors. In October 2011, McAfee introduced two products based on DeepSAFE: Deep Defender to protect endpoints and Deep Command, an addition to McAfee€™s ePolicy Orchestrator platform that gives security administrators secure remote access to devices.
