A Lightweight and Privacy-Preserving Authentication Protocol for Mobile Edge Computing
With the advent of the Internet-of-Things (IoT), vehicular networks and
cyber-physical systems, the need for real-time data processing and analysis has
emerged as an essential pre-requite for customers' satisfaction. In this
direction, Mobile Edge Computing (MEC) provides seamless services with reduced
latency, enhanced mobility, and improved location awareness. Since MEC has
evolved from Cloud Computing, it inherited numerous security and privacy issues
from the latter. Further, decentralized architectures and diversified
deployment environments used in MEC platforms also aggravate the problem;
causing great concerns for the research fraternity. Thus, in this paper, we
propose an efficient and lightweight mutual authentication protocol for MEC
environments; based on Elliptic Curve Cryptography (ECC), one-way hash
functions and concatenation operations. The designed protocol also leverages
the advantages of discrete logarithm problems, computational Diffie-Hellman,
random numbers and time-stamps to resist various attacks namely-impersonation
attacks, replay attacks, man-in-the-middle attacks, etc. The paper also
presents a comparative assessment of the proposed scheme relative to the
current state-of-the-art schemes. The obtained results demonstrate that the
proposed scheme incurs relatively less communication and computational
overheads, and is appropriate to be adopted in resource constraint MEC
environments.Comment: To appear in IEEE GLOBECOM 201
