摘　　要：针对当前用电信息系统多业务并行处理能力需求,提出了一种面向对象的用电信息系统安全通信协议(OS-CP)。OSCP协议采用传输层和应用层双层加密机制实现了用电信息系统的安全防护,并将业务数据根据安全级别进行分类,不同类别的数据采用不同的安全配置模式,实现了业务数据的灵活处理。之后,采用基于博弈论的安全性证明方法证明了OSCP协议的正确性和安全性,并与传统安全通信协议做了性能比较。比较结果表明,OSCP协议的交互次数相对较少,加解密处理效率有了明显提高,安全加密模式配置更为灵活。因此,OSCP协议更适用于当前用电信息系统的业务应用需求。According to the current multi-business parallel processing demand of electricity information system,this paper has proposed an object-oriented security communication protocol(OSCP)for electricity information system.The OSCP mainly uses transmission layer encryption and application layer encryption double layer encryption mechanism to realize the security protection for electricity information system,and which categorizes the business data according to security levels,then,different security configuration modes adopt different categories of data.The correctness and security of OSCP have been proved by the security proof method based on the game theory.The communication performance comparison also has been made between the OSCP protocol and the traditional secure communication protocol such as HSMA security protocol.The comparison results showed that the information interaction times of OSCP protocol is relatively less,the encryption efficiency has been improved obviously,and the security encryption mode configuration is more flexible.Therefore,the OSCP protocol is more suitable for the actual business application demand for the current electricity information system.
