摘　　要：由于RFID系统的特殊性,传统的密钥管理方法已不适用.针对RFID系统,从系统初始化、密钥生成、密钥分配和数据安全传输四个方面提出了一种结合组合公钥算法的密钥管理应用方案.该方案解决了低成本的限制下标签存储量小、计算能力弱问题,与RFID系统终端设备处理能力相匹配.分析表明,此方案具有存储量小、安全性和运行效率较高的特点,为RFID系统的密钥管理体制提供了新的手段.Now, however, traditional teaching methods fail to satisfy the particularity of the RFID system. In this paper, a key management scheme [or RFID is proposed, which combines CPN （Combined Public Key） cryptography. The detailed contents, including initializing system, producing key, distributing key, and transmitting data securely, are described. This solution solves small storage and weak compute capability.problems. It is matched to the processing power of terminal equipment of RFID. The study shows that the approach has some important features, such as small storage, high security and high running efficiency. And it provides new means for key management of RFID.
