In today's rapidly developing era of IoT devices and connected ecosystems, security has become a critical consideration. Realtek Semiconductor Corporation has announced that its innovative RTL8762G/8772G series chips have successfully achieved ARM Platform Security Architecture Level 2 (PSA L2) certification. This certification not only highlights Realtek's commitment and capabilities in the field of security but also sets a new benchmark for the security performance of its products in the global market.

PSA L2 Certification: A Guarantee of Security

ARM's PSA (Platform Security Architecture) is a comprehensive security design and certification framework aimed at helping chip manufacturers and system developers design and deploy high-security devices. The PSA framework builds its security foundation on four levels: Architecture Specifications, Reference Implementations, Security Analysis Model, and Certification Scheme.

PSA L2 certification requires devices to have multi-layered security protection from the chip level to the software level, including Secure Boot, Trusted Execution Environment (TEE), and Secure Update mechanisms, among others.

Achieving PSA L2 certification means that Realtek's RTL8762G/8772G chips met ARM's stringent requirements in the following areas:

1. Secure Boot: The chip must verify the integrity and authenticity of the firmware during startup to prevent unauthorized code from running. The RTL8762G/8772G integrates hardware root of trust mechanisms to ensure the security of the boot process.

2. Trusted Execution Environment (TEE): Provides an isolated execution environment for running security-critical applications and processing sensitive data. The RTL8762G/8772G, through TrustZone design, ensures the high security of critical data and computational tasks.

3. Isolation: Implements isolation between system components of different security levels to ensure that a security issue in one component does not affect the entire system. Realtek employs a combination of hardware and software methods to achieve multi-level isolation on the RTL8762G/8772G chips, including TrustZone for primary isolation between the secure world and normal world, and further isolation within the secure world using the MPU (Memory Protection Unit) and TF-M (Trusted Firmware-M) to separate the PSA Root of Trust and Application Root of Trust.

4. Secure Communication: Provides encrypted communication channels to ensure data is not intercepted or tampered with during transmission. The RTL8762G/8772G hardware supports ECC, RSA, AES, SHA256, TRNG, and the software support for Mbed TLS ensures the security of data at all stages of communication.

5. Secure Update: The chip must have secure firmware update capabilities to ensure that only verified firmware can be installed, preventing malicious updates. Realtek has developed a dependable secure update mechanism to ensure the long-term security of devices.

Realtek's Commitment to Security

Achieving PSA L2 certification reflects Realtek's extensive expertise and technical strength accumulated over years in the field of security technology. Realtek not only focuses on providing high-performance networking and multimedia solutions but also places security at the core of all product designs. The RTL8762G/8772G chips embody this philosophy by integrating various advanced security measures, such as Trusted Execution Environment (TEE), Secure Boot, and hardware encryption engines.

Mr. Jin-Qiu Li, Head of Marketing for Realtek's Communications Network and Bluetooth Product Line Division, stated: "Security is a fundamental requirement for our products. By achieving PSA L2 certification, we demonstrate Realtek's strength in providing highly secure solutions. This not only enhances customer trust in our products but also offers end consumers a safer user experience."

Practical Applications and Market Impact

The security certification of the RTL8762G/8772G chips will greatly enhance their competitiveness in various application areas such as smart homes, industrial IoT, and smart cities. Chips with PSA L2 certification will provide robust security assurance for these devices in diverse and complex application environments, preventing data breaches, identity theft, and device compromise.

Market analysts believe: "Realtek's continuous investment in security and this certification will further consolidate its leading position in the global chip market. As the IoT and smart device markets expand, high-security chips will become a key driver."

Future Outlook

Achieving PSA L2 certification is just a significant milestone in Realtek's journey in the security field. In the future, Realtek plans to continue increasing its investment in security technology research and development, introducing top-tier security standards to more products, and further enhancing the security of the entire connected ecosystem. Equally important, Realtek will continue to closely collaborate with global partners to promote the implementation of high-standard security solutions.

Through this PSA L2 certification, Realtek has once again proven its advanced level and strong capability in the field of chip security. Looking ahead, as security requirements continue to increase, Realtek will continue to lead the industry, driving forward safer and more reliable connected solutions to serve customers and users worldwide.

In summary, the Realtek RTL8762G/8772G chips achieving PSA L2 certification marks a new height. This achievement is not only a high recognition of Realtek's security technology but also provides strong support for enhancing the security performance of IoT devices. Realtek will continue to climb new heights in this field, propelling the advancement of network security technology.
