Corona-Warn-App：追踪德国官方COVID-19曝光通知应用程序的启动
Corona-Warn-App: Tracing the Start of the Official COVID-19 Exposure Notification App for Germany
摘要：
2020年6月16日，德国推出了一款开源智能手机接触者追踪应用程序（“Corona-Warn-App”），以帮助追踪SARS-CoV-2（冠状病毒）感染链。它使用基于暴露通知API的分散式隐私保护设计，其中集中式服务器仅用于分发SARS-CoV-2感染用户的密钥列表，该应用程序每天获取一次。然而，它的成功取决于它的采用。在这张海报中，我们使用直接在其托管基础设施中捕获的Netflow跟踪来描述应用程序的早期采用。我们表明，该应用程序产生的流量来自德国各地-已经在第一天。我们进一步观察到，本地COVID-19爆发并未导致交通量显著增加。
英文摘要：
On June 16, 2020, Germany launched an open-source smartphone contact tracing app ("Corona-Warn-App") to help tracing SARS-CoV-2 (coronavirus) infection chains. It uses a decentralized, privacy-preserving design based on the Exposure Notification APIs in which a centralized server is only used to distribute a list of keys of SARS-CoV-2 infected users that is fetched by the app once per day. Its success, however, depends on its adoption. In this poster, we characterize the early adoption of the app using Netflow traces captured directly at its hosting infrastructure. We show that the app generated traffic from allover Germany---already on the first day. We further observe that local COVID-19 outbreaks do not result in noticeable traffic increases.
