论文摘要
我们引入了量子标志的一种变体,其中非二进制符号被签名而不是位。与Gottesman和Chuang的计划一样,公共钥匙是指纹状态,但我们允许多种方法部分揭示私钥。这种修改的效果是减少了每个消息位消耗的量楼数量。我们提供了一个安全性证明,并提出数值结果,以显示公共密钥大小的改善如何取决于消息长度。
We introduce a variant of quantum signatures in which nonbinary symbols are signed instead of bits. The public keys are fingerprinting states, just as in the scheme of Gottesman and Chuang, but we allow for multiple ways to reveal the private key partially. The effect of this modification is a reduction of the number of qubits expended per message bit. We give a security proof and we present numerical results that show how the improvement in public key size depends on the message length.
