DVB-CSA (Digital Video Broadcast - Common Scrambling Algorithm) is encryption method commonly used to protect the paid channels of digital television. The paper presents a study of its implementation in specialized digital hardware. The algorithm was successfully converted to logic architecture, coded in hardware description language (VHDL), verified and synthesized for programmable logic device (FPGA). For Xlinx Spartan 3 implementation, the expected throughput may be estimated to 100 Mbps in pipelined mode.
