Short Paper: Thor - The Hybrid Online Repository

Mobile environments create significant challenges for secure credential repositories. We examine these challenges with respect to existing repository practices and produce a set of requirements that a repository must meet in order to cope with the harshness of a mobile environment. We also present Thor (The hybrid online repository), a system that fulfills these requirements. Thor leverages preexisting local and remote repositories and enhances their usability and security through virtual organization, credential identifier obfuscation, and password management
