Summary:A method used for encrypting and authenticating data, comprises following steps: at first, cryptograph data blocks (C1-Ci) and corresponding marks (mark 1-mark i) are generated from one or more plaintext data blocks (P1-Pi) by authentication and encryption. Then, a mark tree (3) is generated by the authentication marks (mark 1-mark i). The cryptograph data blocks (C1-Ci) and mark tree data of themark tree (3) are stored in an unauthentic memory (1), and root marks of the mark tree (3) are stored in an authentic memory (2).
