Tongxin UOS achieved a historic breakthrough and won the fourth level certification of secure operating system

According to news on October 8, China’s leading software company Tongxin Software announced yesterday that its independently developed operating system Tongxin UOS successfully obtained the "Network Security Special Product Security Testing Certificate (Secure Operating System Level 4)" issued by the National Network and Information System Security Product Quality Supervision and Testing Center.

This certification marks the UOS has become the first and currently the only desktop operating system to obtain a new Level 4 certificate for secure operating systems since the four ministries and commissions jointly issued a document on July 1, 2023 to stop the issuance of the "Computer Information System Security Special Products Sales License". According to the official statement, the issuance of the certificate complies with the "GB/T 20272-2019 Information Security Technology - Security Technical Requirements for Operating Systems" and "GB 42250-2022 Information Security Technology - Security Technology for Network Security Special Products".

News on October 8, according to the editor’s understanding, the certificate complies with the "GB∕T 20272-2019 Information Security Technology" Operating System Security Technical Requirements" was released by the State Administration for Market Regulation and the National Standardization Administration of China on August 30, 2019, and was officially implemented on March 1, 2020. As a national technical testing standard, GB /T 20272-2019 replaces the old standard GB/T 20272-2006, this standard stipulates the highest standard for the security level of domestic operating systems and is also one of the most authoritative standards. According to the security functions and security assurance requirements, the standard divides the operating system into five security levels. UOS successfully passed the security level 4 certification.

Tongxin UOS has high-standard guidance and comprehensive architecture leadership, and adopts a hierarchical classification theory to improve full-stack security capabilities from multiple dimensions: own security, ecological security, and supply chain security. The operating system also supports Trusted Computing 3.0, which provides a hardware root of trust through the hardware layer combined with a security chip. It provides a trusted cryptographic module, trusted strength, and a trusted audit module at the kernel layer, and implements trusted startup and reliability at the system layer. Confidence measure. This integrated design of software and hardware builds a complete security chain of trust.

In addition, Tongxin UOS desktop version V20 also passed the second-level requirements of the "Security Technical Requirements for Cryptozoology Modules" of the Commercial Cryptometry Testing Center of the National Cryptozoology Administration and successfully obtained "Commercial Encryption Product Certification Certificate"

We reported last month that Tongxin The number of UOS software and hardware adaptations has exceeded 3 million, becoming the first operating system in China to achieve this goal, and has also formed a competitive scale globally. This latest security certification undoubtedly further strengthens the UOS’s competitiveness in the operating system field.
