Core Viewpoint - The independent evolution of the Haiguang C86 architecture provides a secure, controllable, and efficient choice for China's digital infrastructure construction, especially in the context of computing power becoming a fundamental infrastructure [1][38]. Group 1: StackWarp Vulnerability and Its Implications - The StackWarp vulnerability discovered in AMD's Zen series processors exposes a significant flaw in cloud computing's isolation capabilities, allowing attackers to modify running programs and data [2][3]. - The response from AMD to disable simultaneous multithreading (SMT) to mitigate the vulnerability results in a substantial reduction in processing power, halving the server's capacity to support virtual service instances [3][4]. - In contrast, Haiguang's C86 processors are inherently immune to the StackWarp vulnerability due to their architectural design, allowing users to maintain full computational performance without needing firmware upgrades or disabling features [4][10]. Group 2: Technical Differentiation - Haiguang's ability to defend against the StackWarp vulnerability stems from its fundamentally different virtualization technology compared to AMD, utilizing self-developed CSV3 technology to create a new defense mechanism [6][12]. - The C86 architecture has decoupled from the x86 technology route, replacing AMD's platform security processor (PSP) with Haiguang's self-developed security processor (HSC) [12][15]. - The C86 processor integrates a general-purpose C86 core and a dedicated security processor, ensuring a secure boot process and a chain of verification that maintains system integrity from the first line of code [13][14]. Group 3: Three-Layer Security System - Haiguang's C86 architecture features a three-layer security system: native cryptographic technology, proactive trusted computing, and isolated confidential computing [17][18]. - The first layer involves integrating a cryptographic co-processor (CCP) within the processor, allowing for high-speed encryption without the performance penalties associated with traditional software or external hardware solutions [20][21]. - The second layer, proactive trusted computing, extends security measures from system startup to runtime, utilizing TDM technology to continuously monitor and verify the integrity of critical system components [24][25]. - The third layer, isolated confidential computing, employs CSV technology to ensure real-time memory encryption for virtual machines, preventing unauthorized access and data leaks in cloud environments [28][29]. Group 4: Market Position and Applications - Haiguang's C86 architecture has been widely adopted in high-security scenarios, particularly in finance, telecommunications, and energy sectors, achieving a 50% share in trusted computing certified products [27][36]. - The architecture maintains full compatibility with the x86 ecosystem, allowing applications originally designed for Intel or AMD servers to migrate seamlessly to Haiguang platforms without code modifications [37]. - The independent evolution of Haiguang's technology mitigates risks associated with reliance on external architectures, ensuring stable performance and security in the face of global hardware vulnerabilities [38].
