| Abstract: | In this article, we present an authenticated encryption scheme with message linkages used to deliver a large message. To protect the receiver’s benefit, the receiver can easily convert the signature into an ordinary one that can be verified by anyone. Several feasible attacks will be discussed, and the security analysis will prove that none of them can successfully break the proposed scheme. |
