智能电网实际实现的关键挑战之一是细粒度智能计量数据的隐私影响。我们回顾了德国BSI的智能计量系统网关保护配置文件，这是德国实用智能计量隐私的最先进方法。我们的分析揭示了几个问题，可以减少实现匿名性和匿名性。具体来说，我们调查搅动攻击，利用固有的过程中使用的mixymised仪表数据，我们量化的攻击的效果。此外，我们引入GridPriv增强的架构，包括一个不受信任的k-匿名服务，并解决了与BSI的方法在可扩展的，安全的，隐私保护的方式确定的挑战。
One of the key challenges to the practical realisation of the Smart Grid are the privacy implications of fine-grained Smart Metering data. We review the German BSI's Protection Profile for the Gateway of a Smart Metering System, a state of the art approach to practical Smart Metering privacy in Germany. Our analysis reveals several issues that can reduce the achieved anonymity and pseudonymity. Specifically, we investigate churning attacks which exploit processes inherent to the use of pseudonymised meter data and we quantify the attacks' effect. In addition, we introduce GridPriv an enhanced architecture that includes a non-trusted k-anonymity service and that addresses the challenges identified with the BSI's approach in a scalable, secure, and privacy-preserving way.
