针对相关文献提出的基于异或和哈希算法的轻量级射频识别认证技术,对其潜在的危险进行了深入的分析。在此基础之上,结合应用于Internet或应用系统中的传统的安全机制和一些轻量级的节省资源的安全机制,对上述协议进行改进,提出一种新的轻量级射频识别安全协议。该协议适用于现实的系统中,以避免已确认的潜在危险,并充分考虑在RFID系统中,RFID标签低成本的要求、强大的约束性以及对外界不可抗拒性等限制RFID发展的主要因素。 相似文献

In the middle of current finance tsunami, there demand measures from the governments across the border between Hong Kong and Mainland to alleviate the financing difficulties faced by the Hong Kong invested enterprises in Pearl River Delta (PRD). The paper describes the issues surrounding how innovative logistics techniques can be used to overcome border barriers to provide financing services to Hong Kong invested Processing Trade Enterprises (PTE) in PRD. The problems are identified for cross board financing. An analysis tool through risk transfer diagram is developed for service identification. Different financing instruments are reviewed using the tool developed in which the necessary financing logistics functions are identified. Service architecture is given for these financing logistics functions. A case study for cross border financing development in the context of bonded logistics parks shows that a cross border financing logistics park could be a viable approach to facilitating cross border financing development. 相似文献
