Abstract
Group signature schemes existentially provide
anonymity, non-repudiation and can make a mobile
device untraceable. But using group signature only in
designing anonymous key exchange system is time
wasting and consumes much of other computing
resources hence the use of it must be minimal
especially when deployed on resources-constrained
mobile devices. In .this paper, we propose the
combined use of group signature because of its
inherent security properties which are very important
when a mobile user roams in the insecure wireless
network and message authentication code to reduce
the huge computational burden occasioned by group
signature’s expensive public key operations resulting
in unbearable authentication latency. In this paper, we
built two authenticators, a signature based
authenticator and a message authentication code
based authenticator. These models are based on the
Canetti-Krawczyk model. We implemented the design
using Java 8 on Android Studio 2.2 and tested it on
Genymotion based emulator on Oracle VM
VirtualBox. The experiment result showed a
significant reduction in the authentication time when
message authentication code based authenticator was
executed compared to authentication time result in
the group signature based authenticator. We further
compared our model with a similar model and find
that ours was superior in efficiency measured from
authentication latency when a user roams from his
home domain to a visited network and other networks
subsequently while maintaining same security
characteristics.
