One of the most irritating and zombie-like myths about cloud computing is that of its inherent lack of security. Media touts, platform competitors and other naysayers like to wax lyrical about the “risk” to your data from storing or even processing it in the cloud – most of which is complete nonsense. We’ll be addressing some of these myths in more detail before long, so keep your eyes peeled.
关于云计算的最令人烦恼和类似僵尸的神话之一就是其固有的缺乏安全性。 媒体吹捧者，平台竞争者和其他反对者喜欢对通过存储或什至在云中处理数据的“风险”进行抒情处理-其中大多数都是完全废话。 我们将在不久之后更详细地解决其中一些神话，因此请睁大眼睛。
In the meantime, scientists at Vienna’s Vienna Centre for Quantum Science and Technology (VCQ) (part of the University of Vienna) have developed what they claim is an end to end encryption technique using quantum mechanics. In essence, it means you can send data for processing to a cloud environment without it ever being decrypted.
同时，维也纳维也纳量子科学与技术中心(VCQ)(维也纳大学的一部分)的科学家已经开发出他们所谓的端到端使用量子力学的加密技术。 从本质上讲，这意味着您无需解密就可以将数据发送到云环境。
You read that right – this security scheme would allow you to ship data to a remote system to have processing and calculations performed on it while it is still encrypted, meaning at no time does anyone – human or machine – have access to your raw data. Security like that would go a long way toward eliminating all concern for remote data security in the cloud.
您没有看错–该安全方案将使您可以将数据发送到远程系统，以便在仍对其进行加密的同时对其进行处理和计算，这意味着任何人(无论机器还是人)都无法访问您的原始数据。 这样的安全性对于消除所有对云中远程数据安全性的担忧将大有帮助。
量子位和碎片 (Qubits and Pieces)
The concept is called “Blind Quantum Computing”, and it works on the principles of quantum entanglement. The key word here is “Blind”, as the method allows operations to be performed on data packets without the quantum computer ever knowing the contents.
这个概念称为“盲量子计算”，它基于量子纠缠原理。 这里的关键词是“盲”，因为该方法允许对数据包执行操作，而量子计算机永远不会知道其内容。
Using photons to encode the data, the VCQ researchers managed to stage a successful experimental demonstration of the process tied to the Google Docs API. Unfortunately the full paper is restricted behind a paywall so you’ll need to get yourself an account to read it first hand, but the gist of it is this:
VCQ研究人员使用光子对数据进行编码，成功完成了与Google Docs API关联的过程的成功实验演示。 不幸的是， 整个论文被限制在付费专区的后面，因此您需要先获得一个帐户才能第一手阅读，但要点是：
The scheme works on the Qubit level, with the user preparing qubits in a particular state – this state is kept to himself, and is the quantum equivalent of a passphrase. These qubits are then entangled by the quantum computer using a standardized method.
该方案在Qubit级别上起作用 ，用户可以在特定状态下准备qubits-该状态保留给自己，与密码短语的量子等效。 这些量子位然后由量子计算机使用标准化方法进行纠缠。
Specific instructions enabling the quantum computer to process the data are also sent to the quantum computer as qubits – these instructions are tailored specifically to the particular state of each qubit. Once the computer receives both, processing is performed.
使量子计算机能够处理数据的特定指令也以量子位的形式发送到量子计算机-这些指令专门针对每个量子位的特定状态量身定制。 一旦计算机接收到两者，就执行处理。
The clever part is that the nature of quantum mechanics allows the quantum computer to perform computations on your data without ever knowing what it is. Anyone trying to sniff the data or even having access to the quantum computer itself can get at nothing, without knowing the initial quantum state the user specified.
巧妙的部分是，量子力学的本质使量子计算机可以在不知道数据是什么的情况下对数据进行计算。 任何试图嗅探数据甚至访问量子计算机本身的人，在不知道用户指定的初始量子状态的情况下一无所获。
In their demonstration, the scientists performed an “experimental demonstration of quantum mechanics in which the input, data processing and the output remain unknown to the quantum computer”. According to the scientists, during this demonstration of the first known quantum computation, the user’s data stayed perfectly encrypted.
在他们的演示中，科学家进行了“量子力学的实验演示，其中量子计算机仍不知道输入，数据处理和输出”。 根据科学家的说法，在第一个已知的量子计算的演示过程中，用户的数据保持了完美的加密状态。
“The experimental demonstration uses photons, or ‘light particles’ to encode the data,” the team said. “Photonic systems are well-suited to the task because quantum computation operations can be performed on them, and they can be transmitted over long distances.”
研究小组说：“实验演示使用光子或'光粒子'对数据进行编码。” “光子系统非常适合该任务，因为可以对它们进行量子计算操作，并且可以远距离传输。”
This has only been made possible by several other recent research advancements however, and generally speaking quantum computing is still a very limited arena, restricted mostly to the research and experimental domain at the moment, so it could be some time before we see an encryption scheme like this in the wild.
但是，这只有通过其他一些最新的研究进展才有可能实现，并且通常来说，量子计算仍然是一个非常有限的领域，目前主要局限于研究和实验领域，因此我们可能需要一段时间才能看到加密方案像这样在野外。
The development is exciting and should provide powerful new options in the future, although one can’t help wondering if future tech support centers may need to employ physics teachers to explain the process.
尽管令人不禁怀疑未来的技术支持中心是否可能需要聘请物理老师来解释这一过程，但这项开发令人兴奋，并且应该在将来提供强大的新选择。
