中文摘要：
互动用电是智能电网的基本特征之一,针对因互动用电方式而引入的信息安全风险和安全需求展开研究。首先,从风险分析的角度,将互动用电方式下的信息安全与广域环境下的电力信息安全进行定性比较,重点论述了二者在威胁产生的客观条件、主观动机和事故后果等方面的差异。在此基础上,结合互动用电的业务流程和高级量测体系的特点,从保密性、完整性和可用性等信息安全需求出发,提炼出可用性评估、密钥管理和异常行为检测等3个方面的难点问题。
英文摘要：
Customer interaction is one of the basic features of the smart grid.The study is focused on the risk and demand of cyber security stemming from customer interaction.First,in the perspective of risk analysis,the cyber security of customer interaction is qualitatively compared with that of wide area power cyber security with emphasis on the difference between the two in terms of the objective condition,subjective motivation,and consequence of threat.Furthermore,by referring to the business process of customer interaction and features of advanced metering infrastructure（AMI）,the related difficulties including availability assessment,key management and abnormal action detection,are extracted from the cyber security requirements such as confidentiality,integrity and availability.
