随着信息安全的发展，量子密钥分配(QKD)引起了人们的广泛关注。由于对量子性能的要求较低，半量子密钥分配(SQKD)受到越来越多的关注。提出了两种基于GHz状态的半量子密钥分配协议。第一个协议通过与具有较强量子能力的第三方合作，实现一个经典方和一个量子方之间的量子密钥分发。在相同条件下，第二种方案可以实现经典两方之间的量子密钥分配。所提出的半量子密钥分发协议不会受到一些常见的攻击。对于没有足够量子器件的通信方来说，实现量子通信具有重要意义。
With the development of information security, quantum key distribution (QKD) has attracted much attention. Because of the lower requirement on quantum capability, more attention is paid to semi-quantum key distribution (SQKD). Two semi-quantum key distribution protocols based on GHZ states are proposed. The first protocol can achieve quantum key distribution between one classical party and one quantum party by cooperating with a third party with a strong quantum capability. Under the same conditions, the second one can achieve quantum key distribution between two classical parties. And the proposed semi-quantum key distribution protocols are free from some common attacks. It is significant for communication party without enough quantum devices to achieve quantum communication.
