There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Ian MiersTITLE: Cryptography in Context: Bitcoin, Breaches, and Security in the Real World
ABSTRACT:
This talk will cover the design, implementation, and deployment of novel cryptography to solve real world security issues. While advances in computer science have revolutionized many fields and play a daily role in our lives, the security of deployed systems has not kept pace. Addressing real world security issues requires a new approach to cryptography, one that looks at the context in which it will be used and reasons backwards. I will present examples of this approach in two contexts. First, I will take a detailed look at confidentiality for payments and the privacy failures of schemes such as Bitcoin. I will then detail the design, implementation, and commercial deployment of Zcash, the first system to solve these issues and offer confidentiality and public verifiability for cryptocurrencies. Second, I will explore cryptography in the context of security breaches and the reality that attackers will get into systems and access keys, rendering traditional cryptographic protections ineffective. This will focus on applications of puncturable encryption to messaging and device encryption.
BIO:
Ian Miers is a postdoctoral researcher at Cornell Tech working on computer security and applied cryptography. His research focuses on making systems secure by exploring cryptography in the context of real world problems. This includes Zerocoin and Zerocash, the first systems to provide strongly confidential payments on top of public blockchains, and work improving mobile messaging including attacks on iMessage and new techniques for puncturable forward secure encryption. His work has been featured in The Washington Post, The New York Times, The Economist, and denounced in at least two op-eds. He is one of the founders of Zcash, a privacy preserving cryptocurrency based on Zerocash.
