Cloud computing is a rapidly evolving technology that provides shared processing resources and data to computers and other devices on demand. Mobile computing, on the other hand, facilitates the transmission of data, voice, and video. The convergence of these technologies has given rise to Mobile Cloud Computing (MCC), a concept that not only addresses the limitations of mobile computing but also integrates cloud computing into mobile environments to tackle challenges related to performance, security, and resource constraints. MCC is gaining momentum as the number of mobile users continues to grow. Despite its advantages, data privacy and security remain significant concerns. MCC can deliver infrastructure, computational power, software, and platform services to even basic smartphones. However, several security issues need to be addressed, including network security, web application security, data access, authentication, authorization, data confidentiality, and data breaches. Given the limited storage and processing power of mobile devices, data capacity is constrained. To establish a secure MCC environment, it is essential to thoroughly study and analyze security threats. In this paper, we propose an algorithm designed to enhance the security of mobile cloud computing, ensuring data integrity and confidentiality. Additionally, we discuss the security threats present in MCC environments and propose solutions to address these challenges.
