Now-a-days people are using their smartphones for various purposes like uploading data, sharing data, use of online services, etc. along with their primary functions. But the problem with smartphones is that they are having limited computational and storage resources. Use of cloud computing in mobile computing environment solve this problem which also increases the capacity of mobile devices .But the major concern about the use of cloud is the security issue which also becomes the problem in mobile cloud computing environment. We proposed a light-weighed cryptographic mechanism a proxy re-encryption to solve the data integrity, data security issues in which users has to keep only short secret keys for all cryptographic operations in mobile cloud without involvement of any trusted third party.
