摘要

本文提出了一种基于相干态的量子同态签名方案，该方案是一种有效的多流身份认证方法，可提高量子网络的安全性。如果节点的消息长度为n位，则用于签名的状态在跟踪距离上任意接近于0 (log2n)。方案分析表明，该方案是一个量子群同态签名方案，且签名不可伪造。

Quantum homomorphic signature using coherent states

In this paper, a novel scheme for quantum homomorphic signature based on coherent states is proposed, which is an effective approach to identity authentication for multiple streams to enhance the security of quantum networks. The state used for signature are arbitrarily close in trace distance to states of O(log2n), if the length of the nodes' messages is n-bit. The scheme analysis shows that the scheme is a quantum group homomorphic signature scheme and the signature is unforgeable.
