摘要：
We introduce a protocol For QKD based on reusable entangled states. In this protocol, the EPR pairs act as a quantum key to encode and decode information particles. And only an information particle travels between the legitimated users. This improves the security and efficiency of communication. In addition, we show that its extension to a new QSS protocol is also secure and efficient.
