The Internet has advanced so quickly that we can now access any service at any time, from
any location. As a result of this capability, People around the world can benefit from the popularity
and convenience of teleworking systems. Teleworking systems, however, are vulnerable
to a range of attacks; as an unauthorized user enters the open communication line and
compromises the whole system, that, in turn, creates a big hurdle for the teleworkers. Professional
groups have presented numerous mechanisms for the security of teleworking systems
to stop any harm, but there are still a lot of security issues like insider, stolen verifier,
masquerade, replay, traceability and impersonation threats. In this paper, we propose that
one of the security issues with teleworking systems is the lack of a secure authentication
mechanism. In order to provide a secure teleworking environment, we have proposed a
lightweight and secure protocol to authenticate all the participants and make the requisite
services available in an efficient manner. The security analysis of the presented protocol
has been investigated formally using the random oracle model (ROM) and ProVerif simulation
and informally through illustration/attack discussions. Meanwhile, the performance metrics
have been measured by considering computation and communication overheads. Upon
comparing the proposed protocol with prior works, it has been demonstrated that our protocol
is superior to its competitors. It is suitable for implementation because it achieved a 73%
improvement in computation and 34% in communication costs.
