A NOVEL SECURITY ROUTING USING IDENTITY-BASED LIGHTWEIGHT DIGITAL SIGNATURE IN WMSNs

Abstract

This paper presents a lightweight digital signature-based routing message
and node authentication solution for wireless multimedia sensor networks
(WMSNs). The lightweight geographical security routing protocol (ECDSA-TPGF)
is proposed on the basis of improving the original two-phase greedy geographical
forwarding protocol (TPGF), in which we have added the solution Elliptic curve
cryptography (ECC) and cyclic redundancy check (CRC) to create a digital signature
for a sensor node attached to a routing message. This ensures that only sensor
nodes and messages from trusted sources are accepted and participate in the
routing process. By using lightweight authentication methods and efficient
encryption algorithms, the ECDSA-TPGF routing protocol helps prevent node
spoofing attacks and ensures the security of information transmitted over the
network. The effectiveness of the algorithm was confirmed through security
analysis and evaluated by simulation.
