A novel protocol to achieve privacy-preserving universal authentication protocol for wireless communications called Priauth. To secure the communication as the data are sensitive or it requires the users to pay for it. In the algorithms for secure communication a key is shared by H with V and V with users. The key is used to encrypt data transmitted to the servers or users. In privacy based authentication protocols besides the user and its home server, no one including the foreign server can tell the identity of the user; and besides the user and its home server, no one including the foreign server is able to link any past or future protocol runs of the same user.
