摘 要:[目的/意義]在智慧城市环境下针对信息安全监管策略进行演化博弈分析,有利于为智慧城市相关主体有效应对信息风险和漏洞带来的信息安全危机,加强多方位的信息安全监管提供一定参考。[方法/过程]围绕智慧城市信息安全监管中存在的信息安全问题,以智慧城市运营方和信息安全监管方为博弈主体,构建了收益矩阵,通过计算得出6种策略下博弈主体行为稳定的条件,并运用计算机仿真,分析了不同情况下智慧城市信息安全监管双方的博弈行为以及各关键变量对博弈主体策略选择的方向性及程度性影响。[结果/结论]研究发现,当加强信息安全管理的成本低于发生信息安全事件的期望损失时,其双方博弈结果达到理想状态,且智慧城市监管方对运营方处以较重的处罚时,会加快这一过程的收敛。

Abstract:[Purpose/Significance]In the smart city environment,evolutionary game analysis of information security regulatory strategy is conducive to effectively deal with the information security crisis caused by information risks and loopholes,and provide certain reference for strengthening multi-dimensional information security supervision.[Method/Process]Around wisdom city of information security problems in information security regulation,urban operators with wisdom and information safety regulators as the main body in the game,to build the pay-off matrix,calculated the six main strategy game behavior and stable conditions,and using the computer simulation,analyzed the wisdom city information security regulation under different conditions on both sides of the main game behavior as well as the key variables for game strategy choice of direction and degree of influence.[Result/Conclusion]It is found that when the cost of strengthening information security management is lower than the expected loss of information security incidents,the game results of both sides reach an ideal state,and the smart city regulators impose heavier penalties on operators,which will accelerate the convergence of this process.
Key words:smart city;information security supervision;evolution game
智慧城市是以海量信息与创新概念为特征,以实现城市治理的精确化和高效化为目的[1],以大数据、互联网等前沿信息技术为支撑的城市发展新模式[2]。智慧城市以新一代信息技术为依托,极大地助力了城市治理精确化和高效化进程,但信息技术的广泛应用也使得智慧城市较传统城市而言面临更为复杂的信息安全风险。2020年,国家标准化管理委员会发布了《信息安全技术——智慧城市建设信息安全保障指南》,从网络通信等5个不同层次分析了智慧城市建设所面临的信息安全风险,并着重强调了针对智慧城市运营者等智慧城市建设主要角色开展信息安全监管的必要性[3]。……
