| Abstract: | A new information flow model based on encryption and decryption is given out in the paper,according to new information security class and new information flow policy with new concept of object′s Encryption-Mark,and with the classification and integrality grade of object. The new model is reasonable and secure by analysis,and it will rise the positive effect to design information security architecture model. |
