Quantum signature scheme based on a quantum search algorithm
Chun Seok Yoon, Min Sung Kang, Jong In Lim, Hyung-Jin Yang · Physica Scripta · 2014
We present a quantum signature scheme based on a two-qubit quantum search algorithm. For secure transmission of signatures, we use a quantum search algorithm that has not been used in previous quantum signature schemes. A two-step protocol secures the quantum channel, and a trusted center guarantees non-repudiation that is similar to other quantum signature schemes. We discuss the security of our protocol.
