UGSP: Secure Key Establishment Protocol for Ad-Hoc Network

In this paper, we propose a secure key establishment protocol, called UGSP, for wireless ad-hoc networks using tamper proof hardware (TPH) UGSP results in creating a secure communication channel between two nodes without any third party involvement and hence is suitable for ad-hoc networks UGSP is robust to man-in-the-middle attack, passive eavesdropping, active impersonation attacks ensuring source authentication, data confidentiality and data integrity for communication The system is amenable to dynamic addition of new members A comparative evaluation of UGSP with other approaches along with issues of scalability and cost-effectiveness are discussed.
