Ingle 2 PG Student 1 , PG Scholar, Professor 2 , Department of Computer Engineering, Pune Institute of Computer Technology, Pune, Maharashtra, India ABSTRACT Mobile devices and its applications make a new era for storing important data with in mobile device as well as on a cloud; it can be easily to share data, with others. Mobile Cloud computing paradigm is being used because of its low up-front cost. In recent years, even personal computer user, mobile phone users are storing their data at Cloud. Most of the mobile user stored there important information into their personal Mobile Devices. The securities of such a system against potential intruders as well as cloud service provider are the major target for most of the attackers. There is threat to the data in transit and data at cloud due to different possible attacks. By designing a provision which help to those mobile user to secure their data at transit as well as stored at locally on the same device by using Cryptography Encryption Technique, which helps to Store and Backup their personal data in secure Encrypted form with the help of Mobile Cloud Computing Mechanism. Keywords : Cloud Computing, Mobile Cloud Computing, Mobile Device, Security, Encryption, Decryption, Key Management. I. INTRODUCTION Advancements in mobile system with Innovative Application and Decreasing prices of Smartphone devices, with high amount of storage space which make the people to use their local devices for storing their personal information. Most of the time people will even not able to transfer their multimedia information through mail system or Any other messengers application, due to which most of the time people need to Register their Devices with Cloud services provides for Storage Purpose, which is some time not even possible to Purchasing such Application. Our Application helps those users for storage and computational facility to shear their multimedia data with others, and helps to give external facility to store information in cloud account when their system not having sufficient storage. Mobile Cloud Computing becomes Major Trend which is used by most of the organization as well as those people who rely on Mobile Devices. In this era of Mobile Computing, people use their mobile as secondary source to store, sheared there data with other by using the Communication Mechanisms of wireless data Shearing system such as Wi-Fi or through Messengers. Most of the time people use their Mobile Device for Personal usage; it’s often used as a repository for Storing and Backup user’s personal information, such as User Passwords, Bank Account Information and Medical Records. The storage and computational requirement of mobile device by utilizing Cloud Infrastructure by interacting with cloud, Mobile Device can deliver various services to the user, such as healthcare, mobile commerce and online education. Users can upload and store data (photos, medical records) from their mobile device to the Cloud St o r a g e and S h e a r with others, also Mobile Device can offload Computation Intensive tasks to the cloud to overcome its resources limitation and for saving storage
