A Cryptography Model Based on Levels for Protection of MPEG-1 Layer III Bit-streams
Ji Meng, Asic System · Journal of Electron Devices · 2003
This paper introduces the protection of MP3 Bit streams. Cryptography algorithms on MP3 are widely applied in the protection of copyright. We investigate a simple encryption model. Afterwards, Cryptography based on Levels is presented in the end. It provides a effective develop idea for cryptography design.
