动态地

While the strict integrity policy of Biba's model can be used to maintain integrity of data in computer systems, the integrity labels of both subjects and objects in a system are always kept static in SIP, which might lead to denial to some non-malicious access requirements and hence decreases the compatibility of applications Dynamic enforcement of this policy is presented, which can increase compatibility of software while keeping system integrity as strictly as SIP can The implementation of...

Biba模型中的严格完整性政策能够有效地保证数据的完整性，但是该政策中主体和客体的完整性标记都是静态不变的，这会限制进程的一些原本合理的活动，从而降低应用程序的兼容性。提出严格完整性政策的动态实施方案，并给出该方案在基于Linux的安全操作系统RFSOS中的实现。该方案既可以保证系统的完整性，又能提高系统的兼容性。实验证明，这种方案对系统的整体效率的影响小于1%。

Trigger-based Animation employs an object as a trigger to control a series of animations and a message can be controlled by more than one triggers which helps performers to show digital contexts and attract audiences' attention. The learner's attention could be directed to learning by Trigger-based Animations. Moreover, the teacher-student interaction could be enhanced by proper teaching materials design in the Trigger-based Animation environment.
