With the rapid development of Generative AI technology, large language models are accelerating their integration into PCs, smartphones, smart homes, automobiles, robots, and other smart terminals, signaling the arrival of the "Internet of Everything" era. The security risks associated with this are also intensifying. Against this backdrop, the PSA certification program (PSA Certified^TM, hereinafter referred to as "PSA certification") was born, aiming to provide internationally recognized standardized security assessments for IoT chips, software, and devices. Relying on the Arm® Platform Security Architecture (PSA), PSA security certification ensures that IoT devices meet high standards of security through independent and strict testing processes. This certification system is divided into three progressively advanced levels, Level 1 to Level 3, comprehensively covering core aspects such as security scheme review, laboratory questionnaire assessment, and software and hardware attack penetration tests. Currently, PSA security certification has become one of the most promising and valuable security ecosystems globally.

The BK7236 is a highly-integrated 1x1 single-band 2.4 GHz Wi-Fi 6 (802.11b/g/n/ax) and Bluetooth 5.4 Low Energy (LE) combo solution. Using advanced design techniques and ultra-low power process technology, the BK7236 delivers high integration, efficient security, and minimal power consumption for a wide range of advanced IoT applications. The BK7236 deeply integrates ARMv8.1 Trustzone, PuF (Physical Unclonable Functions), international commercial cryptographic algorithms AES/RSA/ECC, and domestic commercial cryptographic algorithms SM2/3/4 hardware units, as well as the IPSS integrated platform security suite, achieving significant improvements in performance and security. This achievement not only shows the continuous innovation and progress of domestic chips in advanced IoT security capabilities but also attracts industry attention to the IoT security ecosystem led by PSA certification.
