Mobile Money Wallet Attack Resistance using ID-based Signcryption Cryp tosystem with Equality Test

Abstract

his paper is an extension of a research work presented at ICSIoT 2019. An attack continuum against the insider attack in mobile money security in Ghana using a witness based crypto graphic method proposed by Alornyo et al. resisted the service provider from peddling with users data for economic gains. Our improved scheme achieves a simultaneous benefit of digital signature in public key encryption (PKE). The adoption of signcryption cryptosystem in our scheme achieved a desired security property of EUF-CMA using the random oracle model.
