量子消息认证码

Quantum message authentication codes

Howard Barnum

摘要:

这篇论文已被撤回,因为错误的证明引理1。没有引理1,主定理的结果(有相同的证明,但省略了引理1的使用,以扩展到一般攻击)只适用于攻击者应用泡利矩阵(量子比特)或广义泡利矩阵的张量积的攻击。由此产生的定理仍然适用于量子信息认证,但本文早期版本中声称的非常强的结果并不成立。这些问题将在与Claude Crepeau、Daniel Gottesman、Adam Smith和Alain Tapp的联合工作中进一步解决。感谢他们和梁黛比发现了这个错误。

英文摘要:

This paper has been withdrawn because of an error in the proof of Lemma 1. Without Lemma 1, the result of the main theorem (with the same proof, but omitting the use of Lemma 1 to extend things to general attacks) only holds for attacks in which the attacker applies a tensor product of Pauli matrices (for qubits) or generalized Pauli matrices. The resulting theorem is still relevant for quantum message authentication, but the very strong result claimed in earlier versions of this paper does not hold. These matters will be addressed further in joint work with Claude Crepeau, Daniel Gottesman, Adam Smith, and Alain Tapp. Thanks to them and to Debbie Leung for spotting the error.
