论文摘要
基于公钥密码学的身份验证和关键协议的当前方法容易受到量子计算的影响。我们提出了一种基于人工智能研究的新方法，在该方法中，传达方被视为使用其私人决策模型反复互动的自主代理。身份验证和关键协议是根据互动过程中观察到的行为决定的。这种方法的安全性在于难以建模有限观察结果的相互作用剂的决策，这一问题也很难用于量子计算。我们释放Pyami，这是一种基于提议的方法的原型身份验证和关键协议系统。我们从经验上验证了对合法用户进行认证的方法，同时检测不同类型的对抗攻击。最后，我们展示了如何使用强化学习技术来训练服务器模型，这些服务器模型有效地探究了客户的决策以实现更有效的样本认证。
Current methods for authentication and key agreement based on public-key cryptography are vulnerable to quantum computing. We propose a novel approach based on artificial intelligence research in which communicating parties are viewed as autonomous agents which interact repeatedly using their private decision models. Authentication and key agreement are decided based on the agents' observed behaviors during the interaction. The security of this approach rests upon the difficulty of modeling the decisions of interacting agents from limited observations, a problem which we conjecture is also hard for quantum computing. We release PyAMI, a prototype authentication and key agreement system based on the proposed method. We empirically validate our method for authenticating legitimate users while detecting different types of adversarial attacks. Finally, we show how reinforcement learning techniques can be used to train server models which effectively probe a client's decisions to achieve more sample-efficient authentication.
