关于随机数的 150 亿美元攻击
2025 年 10 月，当美国政府查扣 127,271 枚比特币时，加密世界陷入恐慌，“比特币被破解了吗？”“政府能破解私钥了？”
真相更简单却更可怕：Lubian 钱包使用了 32 位熵而非 256 位，一张 RTX 4090 显卡只需 4 秒就能破解这些密钥。
问题不在比特币本身，而在于糟糕的随机数。
这场灾难揭示了加密货币的隐秘真相：你的安全性完全取决于随机数生成器的质量，大多数钱包距离彻底失陷，只差一个劣质随机数。
在 zCloak.Money，我们通过三层协同保护，让这种情况在数学上成为不可能。
第一层：你的 iPhone 早已解决了这个问题
每部 iPhone 都配备了安全隔区（Secure Enclave）：一块拥有真随机数生成器（TRNG）的专用芯片，这块芯片不使用可预测的软件随机数，而是利用物理现象：热噪声、量子效应 - 这些从根本上无法预测。
这正是保护 Apple Pay 的同一块芯片，处理着超过 6 万亿美元的支付，Apple 将整个金融生态系统都押注在这块芯片的随机性上，十多年来，它经受了国家级机构、安全研究人员和黑客的考验，无人能够预测它的输出。
当你用指纹创建 zCloak 钱包时，安全隔区会生成具有真正 256 位熵的加密密钥，不是 Lubian 那样的 32 位，不是软件钱包那种“可能随机”，而是真正的、物理的、数学上不可预测的随机性。
让我们换个角度理解：破解 32 位密钥需要 4 秒，破解具有真实熵的 256 位密钥需要 3.67×10^60 年 - 比宇宙存在的时间还要长。
第二层：门限签名 - 无单点故障
传统钱包（包括 Lubian）使用简单模型：一个私钥控制一切，如果这个密钥很弱，就会失去所有，这就像门上只有一把锁 - 锁坏了，就完了。
zCloak 采用门限 ECDSA/Schnorr 签名技术，你的钱包不是由一个密钥控制，而是由多个必须协同工作的密钥分片控制，可以想象成打开金库需要多把钥匙，而每把钥匙都保存在不同的安全芯片中。
即使某个密钥分片的随机性较弱（在安全隔区中这是不可能的，但我们假设一下），其他分片仍会保持安全性，攻击者需要同时攻破多个具有不同熵源的安全芯片 - 这在数学上是不可能的。
这不仅仅是安全性的倍增 - 而是指数级增长，如果一个密钥有 2^256 种可能性，多密钥的门限签名在实际抗攻击性上接近 2^512 或更高。
第三层：多重签名架构
除了门限签名，zCloak 还实现了企业级多重签名，这意味着必须有多个通行密钥（来自不同设备、不同人员）批准交易。
每个通行密钥都：
由不同的安全芯片生成使用独立的熵源在不同时间创建绑定到特定域名
要成功发起攻击，攻击者需要：
攻破多个安全芯片（不可能）预测多个独立的 TRNG（不可能）绕过域名绑定（不可能）同时完成以上所有操作（不可能中的不可能）
数学的现实
让我们对比实际数据。
Lubian 钱包：
32 位熵破解时间：4 秒安全等级：玩具锁
传统软件钱包：
依赖操作系统随机性易受系统入侵影响安全等级：家用锁
硬件钱包：
硬件 TRNG256 位熵安全等级：银行金库
zCloak.Money：
多个安全芯片 TRNG门限签名（指数级复杂度）多重签名要求安全等级：数学上不可破解
企业为何可以信赖 zCloak 钱包
Lubian 事件暴露了一个关键事实：大多数加密资产损失并非源于密码学被破解，而是实现失败，劣质随机数，弱密钥生成，单点故障。
zCloak.Money 的架构让这些失败成为不可能：
不可能有弱熵：安全芯片在物理上无法生成弱随机数不可能单密钥失陷：门限签名需要多个密钥不可能有实现漏洞：我们不自行实现加密算法 - 我们使用经过验证的安全芯片实现不可能静默失败：多重签名意味着多个独立系统必须同时失效
简单的真相
Lubian 损失 1500 亿美元，因为他们用掷骰子般的随机性生成密钥，传统钱包要求你相信他们的随机数生成，硬件钱包更好，但仍有单点故障。
zCloak 不需要信任，我们使用保护数百万 iPhone 的同款安全芯片，结合消除单点故障的门限密码学，再把这一切包裹在多重签名的架构中，让攻击成为数学上的不可能，再把这一切包裹在多重签名的架构中，让攻击成为数学上的不可能。
你的指纹不仅仅是解锁钱包 - 它激活了一个物理上保证不可预测的硬件随机数生成器，创建出数学上保证不可破解的门限签名。
问题不是这是否安全，而是还有什么能比这更安全。
在 zCloak.Money，我们充分研究了 Lubian 攻击案例的技术原理，当你的密钥由安全芯片生成、通过门限签名分布、由多重签名保护时，弱随机性不是风险 - 而是数学上的不可能。

For US President Donald Trump, there would be few bigger victories than having a domestically produced version of the iPhone, one of the most popular tech products in history. Such a prize would validate his tariff plan and campaign promise to bring manufacturing jobs back to America.
And the administration clearly feels this is an achievable goal, especially in the face of the 145% tariffs that it aims to impose on imports from China, Apple Inc.'s current manufacturing hub. The company also has vowed to invest $500 billion domestically over the next four years.
This week, the White House made its stance clear: Trump wants Apple to begin building the device in the US. “If Apple didn't think the United States could do it, they probably wouldn't have put up that big chunk of change,” White House Press Secretary Karoline Leavitt told reporters.

But the reality is far different. Apple is unlikely to move iPhone production to the US in the foreseeable future for a variety of reasons, including the shortage of facilities and labor needed to produce the devices. Moreover, the country lacks the rich ecosystem of suppliers, manufacturing and engineering know-how that — for now — can only be found in Asia.
The company also is more focused on turning India into its new source of US-bound iPhones. Apple's partners are building the world's second-largest iPhone plant in that country, decreasing the company's reliance on China.
Apple's biggest FATP facilities — short for final assembly, test and pack-out — are massive and incomprehensible to many people outside of Asia. They are almost towns themselves, with several hundred thousand people, schools, gyms, medical facilities and dormitories. One major iPhone factory, a complex in Zhengzhou, has even been dubbed iPhone City.
“What city in America is going to put everything down and build only iPhones? Because there are millions of people employed by the Apple supply chain in China,” said Matthew Moore, the co-founder of a startup and a former Apple manufacturing engineer. “Boston is over 500,000 people. The whole city would need to stop everything and start assembling iPhones.”
A representative for Cupertino, California-based Apple declined to comment.
The development of new iPhones and other products still starts at Apple's labs in Silicon Valley. But working with Asia-based component suppliers and other partners begins long before a product actually hits the market. Apple engineers and operations experts spend months or years working closely with Foxconn Technology Group, Pegatron Corp. and other suppliers to customize assembly of new devices.
In addition to its lock on the manufacturing operations, China is home to millions of people educated in operating machinery and the skills needed to build iPhones — a process that still requires a lot of manual work.
“The engineering support to run a factory is not in America,” Moore said. There just aren't enough students studying STEM, or science, technology, engineering and math, he said.
Chief Executive Officer Tim Cook laid out the reasons for relying so heavily on China during a Fortune magazine event in 2017, saying it wasn't because of low labor costs.
“China stopped being the low labor cost country many years ago,” he said. “The reason is because of the skill and the quantity of skill in one location.”
You could fill multiple football fields with state-of-the-art tooling engineers in China, Cook said that the time. “In the US, you could have a meeting of tooling engineers and I'm not sure we could fill the room.”
One popular counterpoint is that Apple should use its cash hoard to buy thousands of acres in the US and create a fully robotic and automated iPhone manufacturing facility. That would remove any human-related challenges from the manufacturing process.
Commerce Secretary Howard Lutnick said as much in an interview with CBS, suggesting that “the army of millions and millions of human beings” is going to be automated.
But that's not yet realistic, according to supply chain experts and people who have worked on Apple product manufacturing. China has access to lower-cost automation and hasn't been able to make such a vision work.
The pace of iPhone development also makes it harder to automate processes because they can frequently change, they said. Much of the equipment needed for production is made in China as well.
While the look of the iPhone hasn't changed meaningfully in years, new materials and internal components — and even the smallest of tweaks to the design — require the company to retool the assembly lines overseas.
“You design the thing, rebuild the factory, and then you only have six months to sell it,” according to a person with knowledge of Apple's supply chain who asked not to be identified. “The pace of change makes it so much harder to automate.”
Though Apple has indeed diversified production of iPhones, reducing the share made in China to below 90%, it's difficult to duplicate the process in other countries. Apple production hubs in Thailand, Vietnam, Malaysia and Indonesia are focused on devices like Macs, AirPods, smartwatches and iPads.
So far, the biggest attempt to create an iPhone manufacturing center outside of China has been in India. And that's taken a decade to come together. Though Apple has a small iPhone manufacturing line in Brazil, that operation is focused on less-advanced models.
For now, at least, the Indian factories will help Apple avoid the Chinese tariffs. Already the company has been filling its US channels — its biggest single market — with iPhones made in India, Bloomberg News previously reported. That country could also be enough, at least for now. The estimated 35 million units it's now making a year could cover a large portion of its needs in the US.
Apple sells more than 220 million iPhones a year and currently offers seven models, which are all sold in multiple colors and storage capacities. That makes the manufacturing process even more complex and the scale offered in China even more important.
According to Moore, simpler products with less frequent changes — like iMacs and iPads — could be easier. Already, Apple handles final assembly of Mac Pro desktops in Texas. But the parts being pieced together are mostly made in China anyway. Moreover, Apple only sells thousands of those computers annually and doesn't update them for years at a time.
“IPhones are a different animal,” Moore said.
