Implementation of Homomorphic Encryption Schemes for Secure Packet Forwarding in Mobile Ad Hoc Networks (MANETs)


Levent Ertaul, Vaidehi


Vol. 7  No. 11  pp. 132-141


In this paper we provide a new scheme to securely forward the message in wireless mobile ad hoc networks (MANETs) by using existing homomorphic encryption schemes. This scheme is an alternative for threshold cryptography (TC) in MANETs to securely forward the message. By using homomorphic encryption schemes we remove the computational cost associated with Lagrange Interpolation scheme used in TC and also increase the success rate of the encrypted message at the destination in MANETs. In this paper we determine the computational cost of the homomorphic encryption schemes such as Domingo-Ferrer’s new Privacy Homomorphism, Domingo-Ferrer’s additive and multiplicative Privacy Homomorphism, Domingo-Ferrer’s Privacy Homomorphism allowing field operations on encrypted data and Mixed multiplicative homomorphism (MMH) and suggest a better encryption schemes to be used in MANETs. We also provide the implementation details of the proposed new scheme in MANETs. In addition we provide an alternative new scheme for Domingo-Ferrer’s new Privacy Homomorphism and Domingo-Ferrer’s Additive and Multiplicative Privacy Homomorphism
