|Abstract:||Retransmitting High Bandwidth Digital Contend Protected (HDCP) audio and video through networks requires to adhere to the HDCP standard and a license issued by Digital Content Protection, LLC. The intention is to prevent unauthorized interception and copying of motion pictures and television programs. While endecrypting HDCP signals in Bluray players, set top boxes and TVs is accomplished with the shelf components, there is no easy HDCP 2.1 solution to en-decrypt contend protected material to be sent over Ethernet, wireless or beroptic channels. This paper describes possibilities to accomplish HDCP 2.1 endecryption and key exchange in an FPGA by sharing hardware and processing power with the already existing soft core processor and such avoiding additional hardware. The following subjects are discussed: Introduction to HDCP, authentication and key exchange, pairing, locality check, session key exchange and FPGA implementation of HDCP functions Programmable Systems on Chip (PSoC). Considerations on which components are better suited to be implemented in logic cells or in rmware and additional discussions about the licensing and key purchase process are made.|
