PROJECT TITLE:

Two-Factor Data Security Protection Mechanism for Cloud Storage System - 2016

ABSTRACT:

In this paper, we propose a 2-factor information security protection mechanism with issue revocability for cloud storage system. Our system allows a sender to send an encrypted message to a receiver through a cloud storage server. The sender only wants to understand the identity of the receiver but no other info (such as its public key or its certificate). The receiver needs to possess 2 things in order to decrypt the ciphertext. The primary issue is his/her secret key stored in the pc. The second factor may be a distinctive personal security device that connects to the pc. It's not possible to decrypt the ciphertext while not either piece. Additional importantly, once the safety device is stolen or lost, this device is revoked. It cannot be used to decrypt any ciphertext. This will be done by the cloud server that will immediately execute some algorithms to change the existing ciphertext to be un-decryptable by this device. This process is completely transparent to the sender. Furthermore, the cloud server cannot decrypt any ciphertext at any time. The protection and efficiency analysis show that our system isn't solely secure however also practical.
