Abstract
A mediated Certificateless encryption scheme without pairing operations is used for securely sharing sensitive information in public clouds. Mediated Certificateless Public Key Encryption (mCL-PKE) solves the key escrow problem in identity based encryption and certificate revocation problem in public key cryptography. mCL-PKE scheme applies to construct a solution to the problem of sharing sensitive information in public clouds. In this system, the data owner encrypts the data while uploading using the cloud generated users public keys based on its access control policies and uploads the encrypted data to the cloud. Cloud partially decrypts the encrypted data for the users after successful authorization. Users fully decrypt the partially decrypted data using their private keys generated while encryption. The confidentiality of the content and the keys is preserved with respect to the cloud, because the cloud cannot fully decrypt the information. Only data owner can encrypt and decrypt the data using keys. Inorder to improve the efficiency of encryption at the data owner, mCL-PKE scheme is used and the overall cloud based system evaluate its security and performance.
