Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob's desired function choice and Bob should not learn any more than what is logically implied by the function value. While decent quantum protocols for this task are known, many become completely insecure if an adversary were to control the quantum devices used in the implementation of the protocol. In this work we give a fully device-independent quantum protocol for XOR oblivious transfer.

一种与设备无关的异或不经意传输协议

不经意传输是一种密码原语，其中 Alice 有两个比特，而 Bob 希望学习它们的某些功能。理想情况下，Alice 不应该学习 Bob 想要的函数选择，而 Bob 不应该学习任何超出函数值逻辑暗示的内容。虽然这项任务的体面量子协议是已知的，但如果对手要控制协议实施中使用的量子设备，许多协议就会变得完全不安全。在这项工作中，我们为 XOR 无意识传输提供了一个完全独立于设备的量子协议。
