经典消息的量子认证

Quantum authentication of classical messages

Marcos Curty, David J. Santos

摘要:

虽然密钥分发可以说是应用量子密码技术的研究最多的背景,但消息认证,即,验证消息始发者的身份和所发送消息的完整性也可以受益于量子资源的使用。传统上,消息身份验证可以通过基于哈希函数的技术来执行。然而,由此产生的协议的安全性取决于适当的哈希函数的选择,并使用长认证密钥。在本文中,我们提出了一个量子认证过程,仅使用一个量子比特作为认证密钥,允许以安全的方式认证二进制经典消息。

英文摘要:

Although key distribution is arguably the most studied context on which to apply quantum cryptographic techniques, message authentication, i.e., certifying the identity of the message originator and the integrity of the message sent, can also benefit from the use of quantum resources. Classically, message authentication can be performed by techniques based on hash functions. However, the security of the resulting protocols depends on the selection of appropriate hash functions, and on the use of long authentication keys. In this paper we propose a quantum authentication procedure that, making use of just one qubit as the authentication key, allows the authentication of binary classical messages in a secure manner.
