Virtualization-based security techniques on mobile cloud computing: Research gaps and challenges
Over the last decade, various researchers have proposed numerous methods for improving the security and privacy of critical data on virtual machines hosted on remote cloud servers, particularly when mobile applications are involved. Annane and Ghazali review those research efforts in this 2019 paper published in the International Journal of Interactive Mobile Technologies and detail the various gaps in that research. After carefully looking at the strengths and drawbacks of numerous techniques, the authors additionally propose the three biggest challenges not well addressed in that research: scalability, credibility, and robust communication techniques. They also suggest future research that will address "three secure policies to protect users' sensitive data against co-resident and hypervisor attacks, as well as preserve the communication of users' sensitive data when deployed on a different cloud host."
