Welcome to the Systems and Internet Infrastructure Security (SIIS) Laboratory in the department of Computer Science and Engineering (CSE) at Penn State, and member lab of the Network and Security Research Center (NSRC). The SIIS Laboratory develops advanced security technologies for critical components of the modern computing infrastructure. Our researchers consider security problems at all levels of systems design, from theoretical cryptography to physical hardware. Our research has been published in top academic venues in security, networking, operating systems, software engineering, and cryptography, as well as featured in many outlets in popular press.

    The following mission statement best sums up the activities of the SIIS Laboratory:

    The SIIS Laboratory promotes student and scientific advancement through the investigation of emerging technologies upon which computer, network, and information security is based.


    I cannot think of a better statement of how I feel about scientific discovery than the following poem by Bill Watterson. I think it truly reflects the dual promise of both fun and discovery, which I feel should be the real objectives of any scientific endeavor. Put another way, life is simply too short to do work that is not both simultaneously engaging and enjoyable. To wit:

    Explorers are we, intrepid and bold,
    Out in the wild, amongst wonders untold.
    Equipped with our wits, a map, and a snack,
    We're searching for fun we're on the right track!

    - Bill Watterson, Author of Calvin and Hobbes
