The HDCP 2.2 Authentication Process – an Introduction

When digital content is transmitted, it is susceptible to unauthorized copying and interceptions. Hence protecting content has become an important factor in the transmission of audiovisual content. In 2003, Intel developed an encryption technique called the High-bandwidth Digital Content Protection (HDCP) protocol to protect audio and video data between a transmitter (transmitting the audio visual content such as a Blu-ray player) and a receiver such as a Monitor. If a transmitting device is transmitting the content HDCP protected then the receiver must also support HDCP in order to receive the content correctly.
