    摘要:

    针对传统跨域密钥协商协议安全性不足问题,提出一种新的跨域量子密钥协商协议。在无证书密钥协商体系下,采用量子密钥协商与经典密码算法结合的方案,提高了协议适应现有通信网络架构的能力。密钥协商过程使用三粒子量子隐形传态,利用量子态不可克隆定理保障协商过程中密钥的安全性。与其他方案相比,本协议具有较高的量子比特效率,并且可以抵抗中间人攻击、重放攻击等多种内部和外部攻击手段。

    Abstract:

    Aiming at the problem of insufficient security of traditional cross-domain key agreement protocol, a new cross-domain quantum key agreement protocol is proposed. In the certificateless key negotiation system, the combination of quantum key negotiation and classical cryptographic algorithm is adopted to improve the ability of the protocol to adapt to the existing communication network architecture. The key negotiation process uses three-particle quantum teleportation, and the quantum state non-cloning theorem can guarantee the security of the key during the negotiation process. Compared with other schemes, the proposed protocol has higher quantum bit efficiency and can resist various internal and external attacks such as man-in-the-middle attacks and replay attacks.
