Voter suppression threats using @Google @Apple Exposure Notification #GAEN have been dismissed as unrealistic: an adversary could achieve the same effect much more easily using fake news campaigns (e.g. @ronrivest in Forbes). This thread attempts to analyze these arguments (1/12) 2. So ask yourself: what would make you more likely to stay home? A social media post of dubious origin that your polling station is contaminated or a personalized state-sanctioned notification of exposure to #COVID19 ?

Given yesterday's news that Exposure Notification is getting enabled on all our phones, it is a good time to analyze the countermeasures to voter suppression threats claimed by @Google and @Apple. Only infected people can upload keys. Inadequate. Attackers may be willing to get infected. A black market for auth codes could develop. Lab technicians can be bribed. Bugs in the app may allow uploads by non-infected people (this happened in the first version of Swiss Covid)
