Confidentiality and integrity dynamic union model based on MLS policy
Yi Liu, Pla Information · Computer Engineering and Applications Journal · 2008
BLP model is the most classical confidentiality model,and Biba model is the most classical integrity model.Most of subject and object have same level of confidentiality and integrity,but BLP and Biba have contradiction in this situation.This paper puts forward confidentiality and integrity dynamic union model,and gives a serial security rule.By importing history label,subject’s security label is adjusted dynamically,making BLP and Biba banded together in deed.The model realizes the union of confidentiality and integrity,and the system has a good usability.At last,an example is presented to explain the model.
