ExOR is an opportunistic multi-hop routing protocol transmitting packets through multiple routing paths which enhances the throughput of wireless network. Diverse attacks happen aiming at wireless network routing and ExOR due to lack of security, so it is necessary to enhance the capability of preventing malicious attack for routing protocol. SecExOR, a secure opportunistic multi-hop routing protocol based on ExOR using key-sharing by Lagrange Polynomial Group and digital signature, is proposed in this paper. SecExOR sets up public and private keys to network nodes for authentication before transmitting of packets. Digital signature using unsymmetrical keys and hash function is employed ensuring reality of routing information.
