INTRODRUTION:

Mobile Cloud Computing $($MCC$)$ is outlined as a revolutionary combination of cloud and mobile technologies that offers advantages like increased computing power and scalability but also poses security risks. It shows the role that cloud computing serves in providing infrastructure and stresses the importance of the integrity, confidentiality, and availability of data in MCC$.$ To reduce security threats, secrecy techniques, and cryptography are essential security measures. The purpose of the present study is to explore these problems, possible solutions, and the creation of trends in MCC security practices to improve data security and confidentiality in mobile cloud computing.

Mobile Cloud Computing The aim of Cloud computing for mobile devices $($MCC$)$ is to boost processing speed, data storage, and computational capacity by mixing cloud$-$based computing with mobile devices. It makes use of the cloud$$s resources to overcome the limitations of handheld devices and provide consumers.

Background:

As a development and extension of Cloud Computing and Mobile Computing, Mobile Cloud Computing, as a new phrase, has been devised since $2009.$ To help us grasping better understanding of Mobile Cloud Computing, let$$s start from the two previous techniques: Mobile Computing and Cloud Computing.

A$.$ Mobile Computing

Mobility has become a very popular word and rapidly increasing part in today$$s computing area. An incredible growth has appeared in the development of mobile devices such as$,$ smartphone, PDA, GPS Navigation, and laptops with a variety of mobile computing, networking, and security technologies.

In addition, with the development of wireless technology like WiMAX, Ad Hoc Network and WIFI, users may be surfing the Internet much easier but not limited by the cables as before.

Thus, those mobile devices have been accepted by more and more people as their first choice of working and entertainment. in their daily lives

B$.$ Cloud Computing

In the era of PC$,$ many users found that the PCs they bought. $2$ years ago, cannot keep pace with the development of software nowadays, they need a higher speed CPU, a larger capacity hard disk, and a higher performance Operation System $($OS$).$

That is the magic of $$Moors Law$$ which urges user upgrading. their PCs constantly, but never ever overtaken the development. of techniques. Thus, a term called $$Cloud Computing$$ burst upon our lives. Cloud Computing has become a popular phrase since $2007.$ However, there is no consensual definition on what a Cloud Computing or Cloud Computing System is$,$ due to dozens of developers and organizations described it from different perspectives.

$-$ Literature Review:

Overview of Cloud Computing:

Cloud computing offers a modern alternative to managing physical data centres. It allows for the leasing of hardware and software as needed, which transforms capital expenses into operational expenses. Cloud environments provide an accessible online portal for users to manage various resources such as compute, storage, network, and applications.

Types of Cloud Models

Public Cloud: All hardware and software are managed by the vendor, reducing the maintenance burden on the user.

Private Cloud: Mimics the public cloud but is hosted within an organization$$s own datacentre, keeping the maintenance responsibilities in$-$house.

Hybrid Cloud: Combines public and private clouds, allowing for flexible hosting of workloads.

Advantages of Cloud Computing:

$.$ Reduces the procurement cycle for deploying new hardware from weeks to minutes.

$.$ Offers scalability and flexibility in resource management.

$.$ Provides cost efficiencies, especially with the ability to scale resources on demand.
