      Wolenetz, Matthew David; Kumar, Rajnish; Shin, Junsuk; Ramachandran, Umakishore (Georgia Institute of Technology, 2004)
      In the near future, we envision sensor networks to transport high bandwidth, low latency streaming data from a variety of sources, such as cameras and microphones. Sensor networks will be called upon to perform sophisticated ...
    • Minimum Information Disclosure with Efficiently Verifiable Credentials 

      Bauer, David; Blough, Douglas M.; Cash, David (Georgia Institute of Technology, 2007)
      Public-key based certificates provide a standard way to prove one's identity, as certified by some certificate authority (CA). However, standard certificates provide a binary identification: either the whole identity of ...
    • Mobile Identity Management: Concepts, Issues, and Techniques 

      Li, Yun; Liu, Ling (Georgia Institute of Technology, 2009)
      This paper takes a systematic approach to examining the basic concepts, the research issues and the state of art technologies in mobile identity management. We examine the concept of mobile identity and argue that mobile ...
