Abstract

The purpose of this report is to research the secure proxy re-encryption method by utilizing post-quantum cryptography. The disadvantages of this method are also evaluated by making an android application and testing this method on different models. The major bottleneck of this method is large encryption keys which take more time to encrypt data. There are three different parts of this methodology owner, user, and SRS (Setup and Re-encryption Server). Public cloud storage is also used in the implementation but that is only used to store data. The owner uploads their encrypted data into the cloud storage and controls the access by ACL (Access Control List). Users can download that data and SRS is responsible for generating encryption key pairs. In this whole process, the encryption key is never shared with CSP (Cloud Service Provider), and SRS has no access to owners’ data. The encryption and decryption processes are handled by the end-user applications. Our method of sharing data is also secured against any type of post-quantum attacks.
