摘要:
該文提出了一種利用糾纏粒子對交換的量子信息簽名方案。在該簽名方案中,Alice根據(jù)消息的編碼對自己的糾纏粒子對作一局域操作,在與系統(tǒng)管理員及Bob進行粒子對交換后測量的結(jié)果即為消息的簽名,Bob根據(jù)三方測量結(jié)果可以驗證簽名。該方案具有絕對的安全性,可以應用在量子通信網(wǎng)絡中,同時還具有量子身份認證的功能,并且在現(xiàn)有技術條件上完全能夠?qū)崿F(xiàn)。
Abstract:
In this paper, an quantum signature scheme is presented which based on the entanglement swapping. In this scheme, Alice performs a local unitary operation on her two qubits according to message code, after swapping qubits with administrator and Bob, Alice gets the signature by measure her qubits, Bob can verify signature via the measurement outcomes of three sides. This scheme is secure absolutely, it can be applied in a quantum communication network, as well as quantum identification, and it is easy to realize by the present-day technologies.
