In an ideal world, physical space of a business can be associated with its
public key. Consequently, a user who is physically in the space can look
up the associated key for that space. Such a property can be achieved if
only the owner of the space can associate the public key (or the
certificate) with it. In other words, this property prevents someone other
than the space owner from claiming another certificate for that space.
The goal of GeoPKI is to enable secure certificate validation (without user
interaction) for situations in which a user interacts with an online entity
associated with the physical space that the the user trusts (and usually is
currently located). GeoPKI enables the owner of a space to associate a
certificate with that space, and enables space-based certificate lookup to
set up a secure channel to the online resource associated with the space.
Such a system enables several secure applications, such as secure
authentication of paywall certificates at an airport or hotel.
Adrian Perrig is a Professor in Electrical and Computer Engineering,
Engineering and Public Policy, and Computer Science at Carnegie Mellon
University. Adrian serves as the technical director for Carnegie Mellon's
Cybersecurity Laboratory (CyLab). He earned his Ph.D. degree in Computer
Science from Carnegie Mellon University, and spent three years during his
Ph.D. degree at the University of California at Berkeley. He received his B.
Sc. degree in Computer Engineering from the Swiss Federal Institute of
Technology in Lausanne (EPFL). Adrian's research revolves around building
secure systems and includes network security, trustworthy computing and
security for social networks. More specifically, he is interested in trust
establishment, trustworthy code execution in the presence of malware, and
how to design secure next-generation networks. More information about his
