Secure DSR routing protocol analysis and design

For designing secure MANET routing protocol, acquiring correct routing information was an important goal. Firstly, security flaws of SRP and Ariadne were analyzed. Then a sufficient condition of secure DSR never returning non-existent route in the presence of active-1-y (y≥1) adversary was presented. Based on this sufficient condition, a new protocol-SDSR was designed. Using strand space as a tool, the security of SDSR was studied, which demonstrated that SDSR satisfied the sufficient condition and would never return non-existence route.
