Title:
A Lightweight, Secure Big data-based Authentication and Key-agreement Scheme for IoT with Revocability
Authors: Behnam Zahednejad
Abstract:With the rapid development of Internet of Things (IoT), designing a secure two-factor authentication scheme for these network is
increasingly demanding. Recently, historical bigdata has gained interest
as a novel authentication factor in this area. In this paper, we focus on a
recent authentication scheme using bigdata (Liu et al.’s scheme) which
claims to provide additional security properties such as Perfect Forward
Secrecy (PFS), Key Compromise Impersonation (KCI) resilience and
Server Compromise Impersonation (SCI) resilience. However, assuming
a real strong attacker, rather than a weak one. we show that their scheme
not only fails to provide KCI and SCI, but also doesn’t provide real two-factor security, revocability and suffers inside attack. Then we propose
our novel scheme which can indeed provide two-factor security, PFS ,
KCI and inside attack resilience and revocability of the client. Further,
our performance analysis shows that our scheme has reduced modular
exponentiation operation and multiplication for both client and server
compared to Liu et al.’s scheme which reduces the execution time by one
third i.e. 6 ms and 30 ms (0.3 ms and 4 ms) for IoT device (server) for
security levels of λ = 128, λ = 256 respectively
