In this project, we propose to consider three major security issues that will address the constraints that are unique to the wireless network and maintain similar quality of services expected by users:

  1. Software Based Stream Cipher Generator for hand-held low-power devices to achieve fast data encryption rate.
  2. Mutual Authentication Protocol over unreliable wireless network between parties with unequal computing power.
  3. Optimal Group-key Distribution Protocols over an insecure broadcast channel allowing key revocation of compromised and/or defected group members.
