Strict Integrity Policy of Biba Model with Historical Characteristics
Hui Liu · Journal of Zhengzhou University · 2011
Strict integrity policy(SIP) of Biba model was used to maintain the integrity of data in computer systems,but it might deny some non-malicious access requirements,and hence decrease the compatibility of applications.An improved SIP with historical characteristics based on the subject's history behavior was presented,which increased the compatibility of the software while keeping system integrity as strictly as SIP could.An implementation algorithm for the constructed enforcement scheme was given.The improved SIP had the same complexity with the ordinary enforcement scheme.
