SPEP: Security Protocol to Enhance Privacy in Pervasive Computing

Pervasive computing world implies privacy, particularly the bad publicity around invasions of privacy, could block the incredible potential of pervasive computing. A brief introduction of the understanding of privacy, and how they relate to the world of pervasive computing are provided in this paper. With the pseudonyms and Bit Commitment techniques, a Security Protocol— SPEP is designed and built. SPEP provides privacy with confidentiality, two-party data authentication, and evidence of data freshness. A secure node-to-node key agreement protocol is implemented, which is practical in minimal hardware of pervasive computing environment and easily matches the data rate of the network.
