上海证券:国产芯片替代加速 OCS光交换开启新纪元
智通财经网· 2025-08-28 06:22
OCS光电路交换机作为基于全光信号直接交换的通信设备,无需光电转换即可实现光信号的路由与转 发,具备低延迟(降低50%以上)、高能效比(无需高功耗交换芯片,单机架能耗降低40%)、无阻塞带宽 (支持400×400端口级联,单端口速率可达800G/1.6T)等显著优势。其信号转换效率理论值可达传统电交 换机的1000倍,功耗仅约十分之一,有望成为下一代数据中心网络的核心设备。 据研讯社数据,2025年谷歌TPU出货量预计达200万颗,2026年将进一步增至300万颗。以200万颗TPU 组网需求测算,仅谷歌一家即将带动约2.3万台OCS交换机出货。上海证券认为,在数据中心规模持续 扩展的背景下,互联互通能力与单卡算力提升同等重要,光电路交换机需求有望加速释放,市场空间广 阔,建议关注国内交换机及智慧网络解决方案供应商。 标的方面 上海证券主要观点如下: H20停产在即,芯片国产化替代逻辑持续强化 消息面上,根据杭州日报微信公众号,早在今年7月,国家网信办就H20算力芯片存在的安全漏洞与后 门风险约谈英伟达,要求其提交说明及证明材料。 产业层面,国产芯片厂商正从概念期进入业绩兑现期,寒武纪25年Q1营收同比大增4 ...

产业浪潮必有牛市!3个视角让你抓牢主线行情
Mei Ri Jing Ji Xin Wen· 2025-08-24 07:04
继上周我写的《这波牛市干这七个方向就足够了》后,今天我们继续牛市话题,主要讨论三个问题: 1.产业浪潮必有牛市 2.目前有哪些产业浪潮的主线和对应ETF 3.当前投资者最大的风险是自己 产业浪潮必有牛市 远的不说了,我们回顾最近10年的行情吧。 2014-2015年牛市:移动互联网全面爆发+新能源汽车获新定位 移动互联网产业浪潮,始于2013年智能手机渗透率突破70%,并在2014-2015年期间硬件供应端和软件应用端均迎来爆 发。 如果你还在怀疑A股牛市都是闭门自嗨,那么昨晚美联储主席的鹰转鸽发言,应该能打破这层顾虑,美元的全球宽松预 期正在强化,跟A股内部的宽松事实即将形成合力,毫无疑问A股上行的趋势还会强化。 与此同时,2015年3月的《政府工作报告》中,首次提出"中国制造2025"的计划;同年5月,国务院印发《中国制造 2025》,"节能与新能源汽车"是重点发展领域之一,明确了"继续支持电动汽车、燃料电池汽车发展,掌握汽车低碳化、信 息化、智能化核心技术。" 锂电池概念板块指数,从2015年初至6月15日的最大涨幅达到122%。即便遭遇后续的巨大调整,但在四季度那波主升 浪里依然录得不小的涨幅。 其中 ...

Core Viewpoint - The article discusses the security risks associated with NVIDIA's H20 chip, particularly the potential for backdoor vulnerabilities, and highlights the broader implications for the semiconductor industry regarding chip security and trustworthiness [1][13]. Group 1: Security Concerns - The National Internet Information Office of China has formally questioned NVIDIA regarding the security risks of its H20 chip, which has been reported to have potential backdoor vulnerabilities [1]. - NVIDIA's Chief Security Officer, David Leber, claimed that all of NVIDIA's GPU chips do not contain any form of backdoor or monitoring software, although this statement raises skepticism about its credibility [2][13]. - The article categorizes backdoors into three types: malicious self-contained, post-hoc cracking, and covert implantation, emphasizing that all chips, including those from major Western companies, are susceptible to such vulnerabilities [3][4]. Group 2: Historical Context of Vulnerabilities - Major Western IC design companies, including Intel, AMD, and ARM, have been reported to have serious vulnerabilities in their chips, with Intel's Management Engine being a notable example of a high-risk backdoor [5][6]. - Recent vulnerabilities in Intel CPUs, such as the Downfall vulnerability, have led to legal actions against the company, highlighting ongoing security issues and the potential for data breaches [6]. - ARM processors have also been found to have critical design flaws that cannot be patched through software updates, necessitating hardware upgrades for resolution [7]. Group 3: Implications for Chip Purchases - The article argues that chips purchased from external sources are inherently less secure than those developed in-house, as they may contain undisclosed vulnerabilities and backdoors [9][12]. - The reliance on foreign technology can lead to a lack of transparency and control over security updates, as seen in the case of Intel's long-standing vulnerabilities [12]. - The H20 chip, being a China-specific version, is suggested to carry greater security risks compared to globally available models, as it is only subject to scrutiny from local researchers [13].

警惕!芯片安装“后门”,招数不少
Huan Qiu Shi Bao· 2025-08-11 22:38
除了硬件"后门"外,周鸿祎表示,从软件层面安置"后门"程序无需硬件改动,也更易实现。他举例说, GPU是很复杂的芯片,相应的驱动程序也非常复杂,更容易隐藏"后门"程序。他表示,这类隐藏在驱动 程序里的"后门"代码可以根据WiFi信息收集设备的具体位置以及设备的工作时长等信息,也就实现 了"追踪定位"功能。由于GPU驱动程序会不定期升级,通常很难对所有驱动程序的升级包进行全面安全 检查,这就给幕后黑手悄悄在某次驱动程序升级时安插"后门"提供了机会。 奇安信威胁情报中心认为,为芯片安置后门时更可能会"软硬兼施"。例如可能在芯片电源管理单元中植 入特殊电路,当接收到特定远程指令时,它可以直接切断芯片核心电源,或者将电压调整到不稳定区 域,导致芯片功能异常,或者改变芯片的时钟频率,使其无法正常工作。另一种可能的实现方式是修改 芯片的引导程序。当芯片启动时,引导程序会检查特定条件(如地理位置信息、授权状态等),如果条 件不满足,就会拒绝启动,或者让芯片在启动过程中降级功能,或者禁用部分高级功能、降低芯片运行 频率或计算能力。 周鸿祎表示,即便美国芯片等硬件厂商不配合,美国情报部门也可能私自在其产品内安置"后门"。他举 ...
