A novel secure Ad hoc routing protocol using one time password

Ad hoc networks are very useful when it is difficult to deploy an infrastructure. In fact, Ad hoc Network is a collection of nodes having no fixed topology and co-operating with each other in order to route packets. This routing is made through special routing protocols. Paradoxically, these characteristics can be the cause of several security problems such as the unauthorized access control. Moreover, most recent Ad hoc network researches have focused on providing routing services without considering security. In this paper, we propose to remedy to this lack by proposing a novel solution securing an Ad hoc routing protocol, AODV, based on the concept of “One Time Password” and baptized OTP_AODV. OTP_AODV allows nodes authentication through the use of OTP and prevents replay attack as well as non repudiation of exchanged control messages. The integrity of the exchanged data control is handled by the use of electronic signatures.
