A Note On Gottesman-Chuang Quantum Signature Scheme
Zhengjun Cao
Abstract
In 2001, Gottesman and Chuang proposed a quantum signature scheme. Unlike classical signature schemes, the public keys in the scheme can only be used once. The authors claim that the scheme is somewhat cumbersome but it serves as a good model and suggests novel research directions for the field of quantum cryptography. In this note, we remark that the Gottesman-Chuang quantum signature scheme is so commonplace and cumbersome that it can not suggest the potential for quantum public key cryptography. The authors ignore an ultimate fact, namely, the cost to grantee the authenticity of a user's public key is expensive in the scenario of Public Key Infrastructure. It entails that a user's public key should be repeatedly usable in the life duration.
