摘　　要：研究了特洛伊木马对量子密码算法的攻击.首先分析了以EPR纠缠量子比特为密钥的量子密码算法在特洛伊木马攻击下的脆弱性.在此基础上,基于非正交纠缠量子比特提出了一个改进方案.该方案能有效地防止特洛伊木马的攻击.Trojan horse attacking strategy on quantum cryptography is investigated. First, the fragility of the quantum cryptographic algorithm employing EPR (Einstein-Podosky-Rosen) pairs as a key against the Trojan horse attacking strategy is analyzed. To prevent the Trojan horse attacking, an improved scheme which makes use of the non-orthogonal entangled states is proposed. This scheme is robust to the Trojan horse attacking, without reducing the security on other kinds of attacking strategies.
