About four months ago, Ed Felten blogged about a research paper in which Hari Prasad, Rop Gonggrijp, and I detailed serious security flaws in India's electronic voting machines. Indian election authorities have repeatedly claimed that the machines are "tamperproof," but we demonstrated important vulnerabilities by studying a machine provided by an anonymous source. The story took a disturbing turn a little over 24 hours ago, when my coauthor Hari Prasad was arrested by Indian authorities demanding to know the identity of that source. At 5:30 Saturday morning, about ten police officers arrived at Hari's home in Hyderabad. They questioned him about where he got the machine we studied, and at around 8 a.m. they placed him under arrest and proceeded to drive him to Mumbai, a 14 hour journey. The police did not state a specific charge at the time of the arrest, but it appears to be a politically motivated attempt to uncover our anonymous source. The arresting officers told Hari that they were under "pressure [from] the top," and that he would be left alone if he would reveal the source's identity. Hari was allowed to use his cell phone for a time, and I spoke with him as he was being driven by the police to Mumbai.
The whole story and audio of that phone call with Hari in the police car are at Freedom-to-Tinker.com."
