| Summary: | Machine-Type Communication (MTC), as one of the essential advancements
of wireless communication, has become a new business development in mobile
communication. Meeting the necessities of control usage of devices and mass
implement transmission is a key issue in the implementation of MTC in the
Long Term Evolution/Long Term Evolution Advanced systems. Likewise, an
authentication scheme is the most important piece of the system as MTC is one
of the procedures that suffers under group authorization requests. The emphasis
of this research is on MTC of group authentication scheme in an LTE/LTEA
network that is based on a pairing-based cryptography in order to obtain a
highly efficient scheme that lessens signalling congestion. In this research, an
authentication scheme has been modified to enhance the performance of group
authentication in an LTE/LTE-A network. High signalling congestion occurs
during the verification phase since every MTC device needs to go through a
full authentication process. The computation of the relevance cryptographic
operations such as pairing, hashing, multiplication and XOR operations consumes
time especially when a large group of MTC devices requests access to the
LTE/LTE-A network simultaneously. Then, the Home Subscriber Server (HSS)
verifies every request message, generates group pairing and even calculates the
system keys (both private and public). Thus, an accumulation of a big number
of MTC devices in a simultaneous authentication process is the main factor that
causes signalling congestion as the computation requires time to authenticate
the LTE/LTE-A network. Therefore, this research proposes a modified group
authentication scheme for MTC in an LTE/LTE-A network in order to reduce
signalling and computational overheads. The proposed method adopts two efficient
algorithms, namely, the Encapsulated Double and Add algorithms which
depend on the Tate Pairing form by the bilinear pairing cryptography. In the improved
group authentication scheme, which has been modified, the dominance of the signalling/computational overhead time is acknowledged. The derived
results indicate that the proposed approach has successfully lessened congestion
problems up to 40 % in terms of computation and up to 30 % in terms of
signalling overhead. In addition, the MTC devices can verify and complete a
simple exchange AKA with the network. The two performance metrics used in
the study are signalling overhead and computation overhead |
