Stephen Checkoway; Code Freeze 2015


Stephen Checkoway: My primary research interests are in (embedded) systems security, health IT security, and voting—particularly in voting security and post-election auditing. Beyond those, I am interested in a number of topics such as tech policy—particularly 4th amendment protections against unreasonable searches and seizures as it relates to computers—modern algebra, category theory, cryptography, programming languages, and compilers.

I am a member of the Johns Hopkins University Information Security Institute (JHUISI) as well as the Center for Automotive Embedded System Security—a collaboration between UC San Diego and the University of Washington. Within JHUISI, I am a faculty member in the Health and Medical Security lab where we work on a wide array of security problems related to healthcare security, as well as other security topics. I am a co-principal investigator of Trustworthy Health and Wellness (THaW), a collaboration between JHU, Dartmouth College, the University of Illinois, and the University of Michigan.

Title: Embedded Systems Security: The Need for a Holistic Approach

Abstract: Embedded systems--computers designed to perform a particular task as part of a larger system--contain the vast majority of processors in use today. Embedded systems are used extensively in transportation systems (e.g., automotive electronic control units and aircraft avionics), house hold appliances, toys, and nearly every other modern device that runs on electricity. By and large, these systems are not designed with security in mind and, as a result, the software that runs on them suffer from the same flaws and vulnerabilities as desktop software from a decade ago. To make matters worse, these devices are increasingly connected to the public Internet and are remotely exploitable.
