Mutual authentication protocol to share files in cloud storage
Reza Parsamehr, Seyed Farshad Hosseini Nezhad · 2016
Nowadays, with deployment of Cloud Computing and its facilities, many users are absorbed in it. People are not satisfied with Cloud's Security and they are afraid to migrate to Cloud environment. We propose a new protocol that allows users to share their data securely on an insecure cloud servers. Our new protocol assures users that their data and information will stay secure. We focused on sharing data, among users in cloud servers. Users can share their data with other users in an encrypted way. We will encrypt their data and send it to Private or Public cloud servers so that servers cannot manipulate or read the content. Users can search specific file names in cloud storage then request it from server. Cloud Server cannot identify users to gain their identification so users can join cloud without jeopardizing their privacy and Ticket Grant Server will keep user's privacy securely. We encrypt all exchange information to prevent MITM and with two level encryption we achieve mutual authentication. Existing protocols are focused on group activities and communications, so they are not optimized and compatible with individual activities and communications. Hence, we are dealing with individual activities and communications and it can extend to group activities and communications.
