Light Weight Secure Data Sharing Scheme for Mobile Cloud Computing

Nowadays more and more data is stored and retrieved through Cloud Computing. With advancement there arises a problem in security. This means the data can be decrypted easily and the content being accessed by strangers and the privacy of the data will be lost. We have introduced a new algorithm known as “Cipher Attribute Based Encryption Algorithm” with symmetric key in our newly proposed light weight data sharing scheme for mobile cloud computing. Light weight in the sense, data with a fairly light storage capacity like files, audio clips etc. will be secured based on our proposed concept LDSS. The LDSS structure is modified and used as an access control in Cipher Attribute Based Encryption (CP-ABE). To reduce the user cost, it introduced attribute description fields to implement lazy revocation which is difficult in CP-ABE working systems. Everything in this operation might not be applicable in all mobile devices because the components are small and flexibility is less. The results from this paper show the issues related to data privacy have been solved in most cases for light weight data sharing scheme.
