Impact of Port Knocking Authentication on Security and Performance: A Mobile Cloud Computing Perspective

Despite of complicated mobile applications which are using on the smart phones due to the latest developments in mobile computing technology, the latest smart-phones are still weak computing devices, which are constrained by limitations in memory capacity, processing potential and battery lifetime. Therefore, Mobile Cloud Computing (MCC) was introduced, which enables access to a pool of storage and computational resources of computational clouds for mobile devices. Nonetheless, security and privacy are important issues in employing the services of computational clouds for off-device storage and application processing services. Current authentication models employ third party security monitoring mechanism and implement complicated mechanism for ensuring security measures which results in resources intensive security mechanism. Therefore, lightweight authentication methods are required to ensure trustworthy and secure environment in MCC. This paper analysis the issues which are arise because of the length of knock sequence and indicates future direction to mitigate these issues to make the port knocking authentication suitable for the MCC.
