The smart grid introduces communication capability into various components of the power system to facilitate information exchange. This also makes the smart grid more vulnerable to cyber attacks ranging from hacking of customer details to disrupting the operation of the power grid. When the provision of security functions does not lead to a "win-win" situation, it means that at least one participant does not gain anything or its profit is less than its loss. As a result, the participant has no incentive to provide security functions. We believe that smart grid security will be fully successful if and only if it makes all participants winners. In this article, we point out that existing smart grid security approaches lead to zero-sum or win-lose situations. Then, we study and suggest how to change these non-win-win situations to win-win situations. We also use network forensics in smart grids as an example to illustrate how to design effective cyber security mechanisms with a win-win objective.

智能电网通信网络的双赢安全方法


智能电网将通信能力引入电力系统的各个组成部分以促进信息交换。这也使得智能电网更容易受到网络攻击，从窃取客户详细信息到扰乱电网运行。当提供安全功能不能带来“双赢”的局面时，就意味着至少有一个参与者没有获得任何收益或者其利润小于其损失。结果，参与者没有动力提供安全功能。我们相信，当且仅当使所有参与者成为赢家时，智能电网安全才会取得完全成功。在本文中，我们指出现有的智能电网安全方法会导致零和或双输的情况。然后，我们研究并提出如何将这些非双赢的局面转变为双赢的局面。我们还以智能电网中的网络取证为例，说明如何设计有效的网络安全机制，以达到双赢的目标。
