Criterion for choosing chaos map to drive image bit permutation based on chaos permutation information entropy is proposed. An algorithm for image bit permutation is designed based on the fact that the output trajectory of chaotic system is very unpredictable. Image smallest granularity scrambling, namely, bit space maximum scrambling is implemented by(More)
An technology of remote injection based on user schemes has been studied. Before using privilege promotion function, users with different privileges have the same running-results about remote injection. After using promotion function, different privileges users get different results by running the same program. This phenomenon has been interpreted and point(More)
