Cloud security has been of utmost concern for researchers and cloud deployers since the inception of cloud computing. Methods like PKI, hashing, encryption, etc. have proven themselves useful throughout cloud technology development, but they are not considered as a complete security solution for all kinds of cloud authentications. Moreover, data sharing in the cloud has also become a question of research due to the abundant use of data storage available on the cloud. To solve these issues, a Kerberos-based time-to-live (TTL) inspired data sharing and authentication mechanism is proposed on the cloud. The algorithm combines the two algorithms and provides a better cloud deployment infrastructure. It uses state-of-the-art elliptic curve cryptography along with a secure hashing algorithm (SHA 256) for authentication, and group-based time-to-live data sharing to evaluate the file-sharing status for the users. The result evaluates the system under different authentication attacks, and it is observed that the system is efficient under any kind of attack and any kind of file sharing process.
