EPC物联网中标签加密算法研究

The Research on Tag Encryption Algorithm of EPC Internet of Things

针对EPC物联网中数据安全性问题,以及传统的PKI系统构建开销过大、认证体系复杂等问题,提出一种轻型的PKI加密算法。该算法结合EPC物联网的特点,通过引入EPC密钥和基于社会学信任协商模型的认证机制,对传统的PKI进行裁减,在不改变传统PKI基本功能的前提下对加密算法及CA管理进行简化,形成了轻型的PKI算法,构建了具有复合物联网特点的安全体系结构。实验表明:改进的算法有效地实现了对EPC数据访问的控制,保证了物联网中的信息传输效率。

For the data security issues in EPC Internet of Things, as well as expensive construction overhead of tra- ditional PKI system, complicate certification system and so on, the paper propose a lightweight PKI encryption algo- rithm. Combing with EPC Internet of Things＇ features, the algorithm introduces EPC key and a certification mecha- nism based on sociology trust negotiation model, and finally constructs a security architecture with composite characteristics. It prunes traditional PKI, and simplifies encryption algorithm and CA management, but it reserves basic function of traditional PKI. The experiment result shows that the improved algorithm can realize the control of EPC data access effectively, and guarantee information transmission efficiency of Internet of Things.
