论文摘要
在这项工作中，我们提出了一项研究，以对TOR网络使用后量子加密原始图，以使其在量子世界中安全。以此目的，首先分析了基础键合材料。我们观察到，打破使用长和中期密钥（通常是RSA密钥）的算法/协议的安全性，对安全性的影响最大。因此，我们研究了量子安全变体的成本。这些包括密钥生成，钥匙封装和解释。六种不同的后加密算法确保评估1级NIST安全性。我们进一步针对TOR电路创建操作，并评估量词后变体的开销。这项比较研究是通过基于甜食的参考实现来进行的，该甜点会以简化的方式模拟TOR。我们表明，可以创建一个量子安全的电路电路，并建议两个版本 - 一个版本可以在纯量子安全设置中使用，一种可以在混合设置中使用。
In this work, we propose a study on the use of post-quantum cryptographic primitives for the Tor network in order to make it safe in a quantum world. With this aim, the underlying keying material has first been analysed. We observe that breaking the security of the algorithms/protocols that use long- and medium-term keys (usually RSA keys) have the highest impact in security. Therefore, we investigate the cost of quantum-safe variants. These include key generation, key encapsulation and decapsulation. Six different post-quantum cryptographic algorithms that ensure level 1 NIST security are evaluated. We further target the Tor circuit creation operation and evaluate the overhead of the post-quantum variant. This comparative study is performed through a reference implementation based on SweetOnions that simulates Tor with slight simplifications. We show that a quantum-safe Tor circuit creation is possible and suggest two versions - one that can be used in a purely quantum-safe setting, and one that can be used in a hybrid setting.
