Content protection for Android devices

Elliptic Technologies expanded its DTCP-IP content protection offering to include support for Android used in a myriad of consumer devices, including DLNA enabled smartphones and tablets.

The Elliptic DTCP-IP Software Development Kit (SDK) offers a security solution that fits perfectly in Android embedded systems and runs in limited resource environments.

It can be implemented within frameworks such as ARM TrustZone, where security critical components are embedded and executed in trusted environments and non-critical components are executed by the host OS, such as Android.

With the Elliptic DTCP-IP SDK, trusted tasks like device authentication and content decryption run in secure mode, limiting attacks on private keys and content, while non-critical tasks such as application management are controlled by the host OS.

“Elliptic has been a leading provider of robust content protection solutions and was the first semiconductor IP licensee to embrace DTLA, the organization responsible for licensing DTCP technology,” commented Vijay Dube, President and CEO of Elliptic Technologies.

The Elliptic DTCP-IP SDK is based on the latest DTCP specifications and supports all four layers of protection: copy control information, device authentication and key exchange, content encryption and system renewability.

The solution integrates seamlessly on Android platforms and it includes sample Java-based transmitter, receiver and key management applications with JNI abstraction layer to the SDK.

The technical demands of the digital home and the need to deliver rich audio and video content will continue to increase dramatically in the coming years. DTCP-IP is a key link protection security technology designed to protect high-value digital content against theft while it is moved between home entertainment devices. At the same time, it allows users to experience high-quality audio and video content not only on HDTVs, PCs and laptops, but also on wireless devices such as smartphones and tablets.
