STS预付费售电标准安全体系研究

摘要

Compared the standard transfer specification (STS) meters measurement with the traditional pre-payment meters mea-surement, their vending electricity methods and security management systems are very different. Based on standards IEC62055 series and development experience on STS pre-payment meters, this paper analyzed the generation of the Token and its using process, and researched the security of the vending electricity method of pre-payment meters measurement and key management system, which provides the guarantee for the deep understanding of standards IEC62055 series and the application of STS pre-payment meters mea-surement.%STS预付费表计与传统的预付费表计相比，其售电方式和安全体系完全不同。根据IEC 62055系列标准，结合实际开发使用的经验，分析了Token码的产生和使用流程，并研究了STS预付费表计的售电方式和密钥管理体系的安全性，为深入理解IEC 62055系列标准和STS预付费表计的推广应用提供了保证。
