摘要

实时数据库管理系统是智能电网调度自动化系统的核心内容之一，其对于智能电网的安全运行起着重要的作用。随着智能电网开放性的增加，实时数据库中的数据安全，尤其是完整性安全问题受到关注。文中提出一种针对智能电网中基于IEC61970标准的实时数据库中数据的完整性恢复算法——RDIR算法。该方法在数据库中数据完整性遭到破坏之后，可以仅回滚恶意事务和受其影响的后继事务，而无需回滚所有的事务，且在恢复过程中可以避免由于事务撤销而产生的撤销冲突，缩短了数据库恢复所用的时间，从而提高了实时数据库系统的生存性。

Abstract

As one of the cores of the dispatching automation system，the real-time database management system（DBMS）plays an important role in the safe operation of the smart grid.Nevertheless，with the increase of the openness of the smart grid，the data security in the real-time database，especially the integrity of the security issues，is becoming a matter of ever-increasing concern.An algorithm for the integrity restoring of the data in the real-time database that conforms to the IEC61970standard，i.e.，RDIR algorithm，is proposed.With this method，after the data integrity is destroyed，the real-time database has only to roll back the malicious and affected transactions rather than all the transactions.Moreover，the undo conflict due to the transaction undo in the recovery process can be avoided，thus reducing the database recovery time and improving the survivability of the real-time database system.
