标题： Quantum protocols for Rabin oblivious transfer

摘要： Rabin不可见传输是密码学任务，其中Alice希望从Bob那里接收一个位，但可能会以1/2的概率丢失。 在本工作中，我们提供了协议设计，这些设计可以产生具有更好安全性的量子协议。 此外，我们为Rabin不可见传输的任何量子协议提供了常数下限。 为了用非对称欺骗定义来量化此任务的安全性，我们引入了欺骗优势的概念，这可能在研究其他非对称密码原语时具有独立的兴趣。 显示英文摘要

摘要： Rabin oblivious transfer is the cryptographic task where Alice wishes to receive a bit from Bob but it may get lost with probability 1/2. In this work, we provide protocol designs which yield quantum protocols with improved security. Moreover, we provide a constant lower bound on any quantum protocol for Rabin oblivious transfer. To quantify the security of this task with asymmetric cheating definitions, we introduce the notion of cheating advantage which may be of independent interest in the study of other asymmetric cryptographic primitives.
