The rise in adoption of mobile cloud computing (MCC) has increased the security concerns and this fact has motivated security practitioners to consider novel lightweight authentication approaches in order to improve the authentication as a service (AaaS). Indeed, the authentication process has a direct effect on client's perception of trust and therefore the authentication method is required to be robust and easy to use simultaneously. In this paper, we have proposed virtual port knocking authentication method which uses port knocking to authenticate users by using the closed port. Moreover, it employs the virtualization concept taken into account as a constructive concept in MCC to enhance the performance which is affected by long length of knock sequence in the basic port knocking. The statistical results indicate that the proposed method offers an acceptable level of security calculated based on the probability of hacking. The empirical results indicate that the imposed buffering load to the cloud gateway is decreased around 4% for the short length knock sequence while, the enhancement is about 12% in case of using the long knock sequence.
