Version 1.7 a new dawn

Speaker: J. Alex Halderman


I'm an assistant professor of computer science at the University of Michigan and Director of Michigan's Center for Computer Security and Society. My research spans software security, network security, data privacy, anonymity, electronic voting, and censorship resistance. I also study the interaction of technology with law, governmental regulation, and international affairs.

Alex is known for developing the cold boot attack against disk encryption, which altered widespread security assumptions about the behavior of RAM, influenced computer forensics practice, and inspired the creation of a new subfield of theoretical cryptography. A noted expert on electronic voting security, he helped lead the first independent review of the election technology used by half a billion voters in India, which prompted the national government to undertake major technical reforms. He introduced ZMap, an open source tool for performing Internet-wide port scans that can probe the entire IPv4 address space from a single machine in minutes. He is also a co-founder of Let's Encrypt, a free, automated, and open certificate authority he is developing in partnership with Mozilla and the EFF.
