Winbond Introduces TrustME™ Secure Flash Memory Implementing the Trusted Computing Group (TCG) Device Identifier Composition Engine (DICE) Architecture

2017/10/24

TAICHUNG, Taiwan – October 24, 2017 -- Winbond Electronics Corporation, a leading global supplier of semiconductor memory solutions, today announced an expansion of its TrustMETM Secure Flash products portfolio based on the Trusted Computing Group (TCG) Device Identifier Composition Engine (DICE) Architecture specification.

As the industry’s first Common Criteria EAL5+ certified Secure Flash, and now with the addition of support for the TCG DICE, the TrustMETM W75F Secure Flash provides designers with secure memory solution for Internet of Things (IoT), mobile, artificial intelligence, and other demanding applications that call for a secure root of trust, privacy, authentication, code and data confidentiality.

The proliferation of Internet-connected clients in consumer and industrial applications increases privacy and security challenges, which can limit the growth of IoT deployments. While the innovation and application of connected things will continue, establishing root of trust and data confidentiality are some of the biggest concerns designers need to consider when developing new connected devices.

TCG DICE Architectures defines new security and privacy technologies applicable to systems and components. The goal is to provide new approaches to enhancing security and privacy with minimal silicon requirements.

“TCG’s DICE offers an effective root of trust for IoT and embedded systems that have constraints in footprint, cost and power, while providing key security benefits,” said Dennis Mattoon, TCG DICE Architecture group chair and Microsoft, said, “The implementation of DICE by Winbond gives designers an option for including strong trust and security.”

“In an increasingly security aware world, we see significant market demand for the robust hardware root of trust which is mandatory for broad and steady adoption of IoT solutions and infrastructures. Winbond TrustMETM Secure Flash strengthens the robustness of root of trust by securing code and data”, said Hung-Wei Chen, Marketing Director at Winbond. “We look forward to continuing our support for secure memory solutions with our technology and expertise to meet the growing demand for secure and flexible systems in the era of IoT”.

Winbond’s expansion of TrustMETM W75F Secure Flash with the TCG DICE enables secure execute-in-place (XIP) to ensure inherent root of trust, create mutual authentication with IoT cloud services and store securely various keys, credentials and certificates. The EAL5+ certified W75F Secure Flash provides protection against physical hacking attacks such as rollback, replay, man-in-the-middle, power analysis and eavesdropping. Comparing to conventional flash devices storing encrypted software, the secure XIP functionality of TrustMETM W75F Secure Flash eliminates the need for software shadowing and decrypting to additional RAM thus achieves higher system level performance.

The TrustMETM W75F Secure Flash feature:

- Advanced Security
Common Criteria EAL5+ secure certification
Supports the TCG requirements for a Device Identifier Composition Engine (DICE)
Individual device key for binding with master
Bus encryption with a strong, one-time key
Data integrity check
Protection against side-channel attacks (SCA)
Strong tamper-resistance features
Secure execution in place (S-XIP) operation

- Low Power, Wide Temperature Range
Single 1.65 to 1.95V supply
2mA active current, <1μA Power-down
-25°C to +85°C operating range

To meet the growing demand for high-volume embedded solutions, Winbond TrustMETM memories are manufactured in Winbond’s wholly owned and secured 12-inch wafer fabrication facility in Taichung, Taiwan.
The first product in the family, the W75F32 at 32Mb density, is in production and available for samples.
Winbond will demonstrate TrustMETM W75F Secure Flash at the TechCon, Oct 24-26 2017 in the Santa Clara (Calif.) Convention Center, US.
