Description
Summary:碩士 === 國立臺灣海洋大學 === 電機工程學系 === 101 === In this thesis, chaos-based level V multimedia signal encryption software with a user-friendly input interface was developed by using the Henon map, an initial value, a bifurcation parameter for the map, two encryption-level parameters , the Microsoft Visual Studio platform and C# programming language. The developed algorithm is fundamentally based on bit-stream encryption. Ten items were present per encryption parameters. Several encryption parameters were designed in the user-friendly input interface. The software is easy to operate and encryption robustness can be increased by periodically updating the set of encryption parameters. Multimedia flies, such as EEG(.eeg), text(.txt, .pdf, .doc, .docx), picture(.jpg, .bmp), audio(.mp3, .wma), and video(.mp4, .wmv), were used for encryption test. The test results showed that the encryption robustness of Level V was superior to that of LevelsI and II, and that the encryption speed of Level V was faster than that of LevelIII and IV.
