With the growing rate of cloud computing and Information sharing, there is a growth in users and security breach into the system and data. Cryptography based on identity has allowed us to define an innovative solution to ensure the confidentiality of data stored on remote servers. This paper presents, data security technique based on AES (Advanced Encryption Standard) cryptography approach for secure data sharing among users of the cloud. Our approach is to provide secure data before storing on the cloud using the AES algorithm. Using this approach only authorized users of the application can access the available resources and facilities. In this research proposed a new algorithm called DSICE (Data Security in Cloud using Encryption), which encrypt the file using secure key, uploaded by the user at the cloud end and DSICD (Data Security in Cloud using Decryption), which decrypt the file data using secure key from the cloud at the other end. The application has been implemented through a multi-tier web application based on Java technology, Apache Server and Mysql database. Security of data can be reached using AES cryptography and the overall system has been tested using the JMeter application and the comparative study was taken into account between localhost and cloud.
