Domestic quantum security chip successfully tested, quantum cryptography technology achieves double encryption!
The quantum-resistant cryptographic chip AHC001 jointly developed by Guoxin Technology and Zhengzhou Xinda Yimi Technology Co., Ltd. has successfully passed internal testing , which is a major breakthrough in the field of domestic quantum security.
It is understood that the AHC001 chip adopts the domestic 28nm process and is equipped with an independent CPU core, achieving a breakthrough in "high performance + low power consumption". Its typical working power consumption is only 350mW, and its static power consumption is as low as 0.13mW, which is equivalent to the energy consumption level of a smart bracelet in standby mode . This feature makes it particularly suitable for energy-sensitive scenarios such as mobile devices and edge computing nodes.
In addition, Guoxin Technology has achieved two core breakthroughs in AHC001 chip technology.
First, a reconfigurable quantum-resistant cryptographic algorithm engine is integrated into the chip , which supports the international mainstream Kyber encryption algorithm (such as Kyber512/768/1024) and Dilithium digital signature algorithm (such as Dilithium2/3/5), and is compatible with traditional algorithms such as the national encryption SM2/SM3/SM4.
Secondly, the chip has a built-in true random number generator and integrates multiple layers of protection mechanisms such as voltage detection, temperature detection, and light detection to resist side-channel attacks and hardware tampering from a physical level . In addition, its reconfigurable characteristics allow flexible switching of algorithms through instructions, leaving room for expansion for future iterations of anti-quantum standards.
In other words, the uniqueness of Guoxin Technology AHC001 lies in supporting the "dual-mode coexistence" of traditional cryptography and quantum-resistant cryptography . For example, in the financial system, existing businesses can continue to use the SM2 algorithm, while new businesses gradually migrate to the Kyber or Dilithium algorithm to avoid business interruptions caused by technology upgrades . This gradual transition strategy provides a buffer period for security upgrades for various industries.
Top 10 OSAT Companies of 2024—Mainland China Players See Double-Digit Growth.
JCET took third place with $5B in revenue (+19.3% YoY). Demand for consumer electronics improved as semiconductor inventories began clearing in late 2023. The ramp-up of new platforms in AI PCs and mid-range smartphones helped JCET quickly fill capacity for standard packaging services.
Tongfu Microelectronics recorded $3.32B in revenue (+5.6% YoY), buoyed by a rebound in demand for communications and consumer electronics. A strong performance from key customer AMD also supported revenue stability.
HT-Tech secured sixth place with $2.01B in revenue (+26% YoY), with the highest annual growth among the top ten OSATs. The company not only mass-produces low- and mid-end packaging but is also investing in high-end development, focusing on applications such as AI, HPC, automotive electronics, and memory, with a strong local customer base in China.
WiseRoad ranked seventh with $1.56B in revenue (+5% YoY). Growth was driven by recovering semiconductor demand and technological upgrades. Additionally, the retreat of some foreign competitors due to the U.S.-China tech conflict has allowed TFME to expand its domestic footprint.
"2D materials" is the key phrase. The thickness of 1nm is of the semiconductor layer, MoS2, IIRC.
This is an old news. The headline of this piece sounds sensational for attention seeking if not outright wrong. The RISC-V chip made by this Chinese research team was actually not complicated at all, IIRC. It was just a showcase of manufacturing logical semiconductors from 2D materials (hence the mentioning of "1nm thick"). The same team published another paper later on manufacturing memory chips from the same 2D materials, making them the front runner in this field in the world.
A more serious report on this particular RISC-V chip has been posted by other members on this forum a few months ago.
