Recently, Zhangjiang Enterprise XCHI Technology G9 gateway chip obtained the "Commercial Cryptography Product Certification Certificate" certified by the Commercial Cryptography Testing Center of the State Cryptography Administration (hereinafter referred to as the "State Secret Bureau"), this certification covers the security level of the security chip, cryptographic algorithm, security chip interface, key management, sensitive information protection and other multi-dimensional projects of the comprehensive assessment, Xinchi Technology successfully passed all project certification, becoming the first batch of domestic automotive chip enterprises to obtain the national secret certification.
It is understood that before the core chi technology in the automotive chip functional safety has made remarkable achievements, in just three years through the AEC-Q100 reliability certification, ISO26262ASILD functional safety process certification, ISO26262ASILB functional safety product certification. The blessing of the national secret certification has also made Xinchi Technology the first four-in-one vehicle specification chip enterprise in China.
With the gradual maturity of the Internet of Vehicles ecology, the synergy between people and vehicles will greatly increase the close communication between cars and cars, cars and people, and cars and roads. In addition, under the trend of "software-defined cars", future OTA upgrades will be more frequent, and the information interaction in any link will be hacked, which may cause serious security accidents.
It is reported that the G9 central gateway chip of Xinchi Technology adopts a multi-core heterogeneous structure and has a built-in high-performance HSM acceleration module, which is designed in full accordance with the national secret standard from the beginning of the design. Compared with the traditional external independent encryption chip, the performance of the HSM encryption module of XCHI Technology is more than 200 times.
Xinchi Technology said that in the new four-span large-scale test in 2020, the message verification and signature of the company's G9 gateway reached 3800 times /s, which means that the information of more than 300 cars can be exchanged at the same time per second, and the performance performance ranks first in the chip test group of that year.
