Quantum resistant NTRU-based key distribution scheme for SIP

A ECC-based key distribution protocol for SIP environment is proposed by Arshad et al. However, traditional public key cryptosystems such as ECC and RSA is vulnerable to quantum computing attacks. In this paper, to resolve theses security weakness, we propose a key distribution protocol using the NTRU of lattice-based cryptosystem. Our proposed scheme is applied to quantum environment efficiently.
