High-bandwidth Digital Content Protection (HDCP) Solutions
AuthenTec’s newest content protection solution allows semiconductor and appliance vendors to implement a complete HDCP2.1 solution into silicon and consumer devices. It supports integration into a highly secure implementation by protecting all of the encryption keys and secure computations. The security module of the HDCP2.1 protocol is available on a TrustZone-based software platform or as a dedicated, highly secure and optimized hardware module.
The HDCP specification was developed by Intel Corporation to protect digital entertainment content across multiple interfaces including IP-based connections. It provides a robust, cost-effective and transparent method for transmitting and receiving digital entertainment content to digital displays via wireless connections such as Wi-Fi, WHDI, WirelessHD and wired connections such as USB, Ethernet, DiiVA, HDMI and DVI. HDCP has broad industry support from the major players in the digital entertainment value chain, including major motion picture studios such as The Walt Disney Company, Warner Bros., and Sony Pictures Entertainment.
AuthenTec’s solution is comprised of the following software and hardware IP components:
DRM Fusion Agent/HDCP: The HDCP solution can operate in pure software mode or integrated into a protected stand-alone software environment. In other applications, the secure part of the HDCP solution can run inside a TrustZone-based secure environment or inside the SafeXcel EIP-115 hardware module. This software offering enables maximum flexibility and security to handset, set-top box, and TV manufacturers.
The HDCP2.1/DTCP-IP High-bandwidth Digital Content Protection software provides all required features for a complete content protection solution which also includes all control and management software for the HDCP and DTCP-IP standards. Besides the cryptographic functions and secure computations module the software includes the implementation of the state diagrams as defined by the HDCP2.1 and DTCP-IP standards and supports the TCP/IP based communication between a transmitter, receiver and repeater (bridge).
The HDCP software development kit (SDK) is designed from the ground up with a flexible structure and API to support current and new applications. It can be used for security plane processing on a range of processors and operating systems.
The HDCP 2.1 standard is backward compatible with HDCP/HDMI 1.x devices. The HDMI 1.x SDK provides compatibility and converter support to interoperate HDCP 2.1 and 1.x applications.
The HDCP2.1/DTCP-IP High-bandwidth Digital Content Protection software provides all required features for a complete content protection solution which also includes all control and management software for the HDCP and DTCP-IP standards. Besides the cryptographic functions and secure computations module the software includes the implementation of the state diagrams as defined by the HDCP2.1 and DTCP-IP standards and supports the TCP/IP based communication between a transmitter, receiver and repeater (bridge).

The SafeXcel EIP-115 hardware security module can be used seamlessly with this software by replacing the security required part of the protocol. This offers the highest level of security and complies with the latest HDCP/DTCP-IP content protection specifications. Since the software includes specific APIs for DRM, it can be used in combination with AuthenTec’s DRM Fusion software to implement a complete, end-to-end content protection solution.
SafeXcel EIP-115 is a dedicated HDCP hardware engine that protects keys and sensitive operations and accelerates encryption and decryption operations to enable protection of uncompressed and compressed, full HD content. SafeXcel EIP-115 works seamlessly with AuthenTec’s existing SafeXcel packet engines and SafeZone secure platform offerings. These hardware offerings enable chip makers to enhance their products to support the latest HDCP standards.
