Abstract: DRM (digital rights management) has no well-known standards about encryption algorithms. This paper proposes a novel FCSR (Feedback with Carry Shift Registers) based keystrem cipher generator for DRM. The novel generator has passed the NIST statistical test, which shows the pseudo-random properties of the novel keystream generator are ideal. We simulate the generator using VHDL under Quartus II. Simulation shows that the proposed generator has better performance under the same target device.
