NanjingJune 25, 2026 /PRNewswire/ — Recently, the intelligent cryptographic key product independently developed by NARI has successfully passed the Commercial Cryptography Security Level 3 certification (referred to as “National Cryptography Level 3”) from the State Cryptography Administration. As the first enterprise in the power industry to obtain this certification, NARI has achieved a significant breakthrough in the application of commercial cryptography in power systems.
NARI’s subsidiary, Beijing Kedong, focusing on the core protection needs of the power industry, has developed the KDKEY-5000-ZK intelligent cryptographic key. The product boasts outstanding core advantages and features three key characteristics:
Miniaturized Integration Feature
It integrates multifunctional detection circuits and an independent power supply battery on a limited-size PCB board, successfully breaking through the technical bottleneck of miniaturized modules that meet cryptographic Level 3 security requirements. This achieves a balance between miniaturization and high security, better adapting to the deployment needs of power industry products.
Multi-Factor Authentication Security Feature
By incorporating fingerprint biometric recognition on top of the traditional PIN code, it establishes a dual authentication mechanism of “what you know + what you are.” This effectively prevents security risks such as unauthorized lending or multi-user sharing of the intelligent cryptographic key, further enhancing the security and uniqueness of identity authentication and eliminating the risk of unauthorized use.
System Adaptation Practical Feature
This product innovatively builds an integrated application system of “unified adaptation—cryptographic service—collaborative management,” achieving seamless integration of cross-platform cryptographic services. It solves the problems of inconsistent cryptographic service standards, poor compatibility, and difficulty in unified management among different manufacturers and platforms in power monitoring systems, providing reliable cryptographic services for operators, security equipment, and business systems.
During the certification testing phase, the R&D team underwent multiple rounds of software and hardware testing and security technology verification, successfully passing a comprehensive review by expert teams from the State Cryptography Administration covering technical systems, product architecture, cryptographic module implementation, and security management processes. The successful certification of this product marks NARI’s industry-leading level in the field of cryptographic application and identity authentication security in power systems, representing a milestone in ensuring the security of key business operations in new power systems.
Currently, this product has been piloted in regions such as Jiangxi, Zhejiang, and Ningxia, providing a replicable and implementable practical model for the construction of commercial cryptographic systems in power monitoring systems, laying a solid foundation for nationwide promotion in the future.
