Abstract

Mobile ad hoc networks (MANETs) are a collection of wireless mobile nodes dynamically forming a local area network or other temporary network without using any existing network infrastructure or centralized administration. Because all of the nodes communicate each other based on the routing protocol, and an attacker could manipulate a lower-level protocol to interrupt a security mechanism in a higher-level one, securing routing protocol is an important issue in MANETs. Recently, there exist several proposals that attempt to architect a secure routing protocol for MANETs. Ariadne is the flagship protocol for securing the dynamic source routing protocol, and it can defend against the alteration of route message and prevent various types of Denial of Service attacks. Unfortunately, in 2006 Acs et al. stated Ariadne will suffer from a new attack, and proposed a provably secure on-demand source routing protocol, called ENDAIRA, against such an attack. However, their method is not actually secure against the Sybil and wormhole attacks. Therefore, in this paper we design a secure routing scheme using the self-certified public key cryptosystem, elliptic curve cryptosystem, pre-hashing, and nonce techniques against such attacks in ENDAIRA. Finally, we analyze the security and discuss the superiority about our proposed scheme.
