In a world overrun with digital identities and passwords, network access privileges are often outdated and overly broad. A new technology--called attribute-based encryption (ABE)--promises to significantly advance the field of trustworthy computing by basing access on a person's job description or constellation of role-based characteristics rather than identity.
This two-faceted project specifically addresses the research challenges associated with ABE and considers future directions for investigation. One facet examines ABE encryption, including a multi-authority system; the other considers the challenges of integrating ABE into trustworthy systems. In addition, the project involves construction of an ABE source-code library that supports both key and cipher text policies.
