Furthermore, our scheme provides secure mutual authentication and strong user credentials’ privacy even if the session-specific temporary information is unexpectedly revealed to an adversary by session exposure attack.
The simulation results using the widely-accepted AVISPA tool for
the formal security verification reveal that the proposed scheme
is also secure against replay and man-in-the-middle attacks. The
practicality of the proposed scheme for measurement of various
network parameters is evaluated using the broadly-accepted NS2
network simulator. Our scheme reduces the computation and
communication overheads of the mobile users. Thus, the efficiency
along with more security functionalities make our scheme is very suitable in the distributed mobile cloud computing environment
as compared to the other related existing schemes.
