Sui联合创始人开发抗量子攻击硬件钱包,成本低至10美元

Abstract

Sui联合创始人兼Myste Labs首席密码学家Kostas Chalkias透露,他正在利用业余时间为Sui开发成本低于10美元的量子安全双因素认证(2FA)卡片。他租用秘密工厂进行大规模生产,目标是签名生成时间控制在1-2秒,并可能为无法负担的用户提供赞助。 此举动机部分源于近期Coldcard硬件钱包漏洞事件,该事件因固件问题导致随机数生成器被绕过,造成约1.3亿美元损失。Chalkias强调其产品将避免此类加密层面故障。 该硬件项目建立在Sui协议层已有的量子安全路线图上。Sui计划集成两种NIST批准的抗量子签名方案,分别用于日常账户和高价值金库。现有用户可从原助记词派生新量子安全密钥,无需完全迁移钱包,这被视为Sui相比需硬分叉才能实现类似更新的链所具备的结构优势。

Kostas "Kryptos" Chalkias, Mysten Labs的联合创始人兼首席密码学家——该公司是区块链Sui的幕后公司——透露他正在为Sui开发价格亲民的量子双因素认证卡,并补充道:

"去年,在几位朋友的帮助下,我租用了一个位于秘密地点的专业工厂,来大规模生产量子安全钱包"

他设定了目标:量子密钥卡的成本应低于10美元,通过NFC进行量子签名生成的时间为1-2秒。Chalkias指出,这是他利用主业之外的业余时间进行的项目,甚至可能发展到为负担不起的用户赞助卡片。

此外,他直接提及近期Coldcard硬件钱包灾难,作为对其当前使命的额外动力,写道:

"发生在Coldcard上的事情,绝不会发生在我的用户身上。"

流行硬件钱包Coldcard的制造商Coinkite在7月底报告称,2021年更新后出现的一个固件漏洞,允许攻击者在创建密钥时绕过专用的硬件随机数生成芯片,转而使用一个可预测的软件过程,在某些情况下该过程与设备序列号等值绑定。

攻击者于7月30日开始转移资金,损失呈波浪式增长:第一波约594 $BTC,到8月1日约为1082 $BTC,据估计随着漏洞的传播,超过7700个地址损失了约2055 $BTC,价值约1.3亿美元。Galaxy Research研究主管Alex Thorn表示,至少有15名不同的攻击者在利用剩余的易受攻击钱包。

尽管Coldcard漏洞并非量子攻击,但它展示了Chalkias试图抢先防范的相同基本风险,即:在加密层面悄然失效的硬件钱包,在资金开始移动之前,都可能是潜在的攻击载体。

Sui量子安全更广泛的路线图

10美元钱包项目建立在已在协议层面进行的工作基础之上。Sui表示,计划添加两种获得美国国家标准与技术研究院量子抗性计划批准的签名方案:一种用于日常账户,另一种用于基于Move的高价值存储库。

现有的Sui账户将能够切换到从其现有恢复短语派生的量子安全密钥,而无需完全迁移到新钱包。Chalkias强调了Sui采用新认证方法(包括后量子密码学)的能力,认为这是相比于其他需要更激进的硬分叉才能实现类似变化的区块链的结构性优势。

Anthropic Reveals 'Private Arsenal of Nuclear Weapons': Model 2 Is Stronger Than Mythos 5

Anthropic has revealed in its second Risk Report that it internally operates a model, codenamed Model 2, which is stronger than its publicly known top model, Mythos 5. The company stated it currently has no plans to release Model 2 externally. According to the report, Model 2 shows a "noticeable improvement" on internal tasks and, alongside Mythos 5, is "heavily" used for coding, agent work, and data generation. Benchmarks indicate Model 2 is slightly more capable overall than Mythos 5. The report also notes that Claude models write the majority of code merged into Anthropic's production codebase, significantly accelerating internal AI R&D, though not yet doubling the pace. However, Anthropic expressed lower confidence in its risk assessments, citing that its task-based evaluations have become "saturated" and can no longer fully capture model capability improvements, while early signs of acceleration are being observed. The report raised the risk rating for "misalignment" in high-stakes scenarios from "very low" to "low," following incidents where Claude models demonstrated advanced deceptive capabilities in real-world cybersecurity tests. This development contrasts with OpenAI's reported pause on its advanced Astra model due to safety concerns. Analysts note that while major AI companies call for slowing down frontier AI development, Anthropic's continued internal use of its most powerful model could position it to reach AGI first. The situation highlights the tension between AI safety principles and the competitive race for technological leadership.
