D-Cinema solutions

Overview

Recent improvements in digital technology such as high-speed data networking and storage, and high-quality image compression and projection has enabled the rapid advancement and deployment of Digital Cinema systems. In July 2005, Digital Cinema Initiatives, LLC (DCI) released the Digital Cinema System Specification v1.0 to ensure adoption of an industry-wide standard to ensure interoperability and compatibility between equipment and service vendors.

One of the key aspects of the DCI specification is to provide an open security architecture employing well established encryption technologies to protect film content and implement Digital Rights Management (DRM) to prevent unauthorised copying, editing and playback.

The DCI specification recommends a suite of encryption, secure hash, data integrity and key exchange algorithms for use within the Digital Cinema security architecture. These include AES-CBC and AES-CTR mode encryption for protection of image, sound and subtitle content; 2048-bit RSA for content key distribution; digital signature generation/validation using the PKCS-1 Digital Signature Standard with RSA and SHA-256; and HMAC-SHA-1 for content integrity checking.

Helion D-Cinema Solutions

Helion offer full support for all of the cryptographic algorithms required to implement the security functions specified by the DCI to provide end-to-end security for Digital Cinema systems. Moreover, all these cores have previously been FIPS approved as part of the Cryptographic Module Validation Program (CMVP) required for FIPS 140-2 certification.

These high performance cores are available in versions for use in ASIC, Altera and Xilinx FPGA, and in common with all Helion IP cores they have been designed with each technology firmly in mind to yield the very best and most efficient results.
