Content Protection for Recordable Media (CPRM)
Introduction
With the market proliferation of various digital media devices, the demand from the entertainment industry content providers for protecting copyrighted material has increased. To address this need, a consortium of companies, called the 4C Entity Corporation, created the Content Protection for Recordable Media (CPRM) Specification. The CPRM specification defines a secure and renewable method for protecting digital content stored on a number of physical media types including SD memory cards, portable ATA hard drives and other devices authorized by the 4C Entity.
The CPRM specification utilizes a common set of cryptographic procedures in each of its implementations. However, the implementation of the CPRM technology is dependent on the type of physical media. The physical media devices must be CPRM compliant in order for the algorithm to function correctly.
QuickLogic’s highly secure ViaLink technology provides an ideal platform to implement algorithms such as CPRM. Its metal-to-metal programmable interconnect makes it virtually impossible to crack the cryptographic keys. And, the ViaLink programmability allows customized CPRM implementations based on the storage media required.

Serial ID:
Introduction
As more copyrighted material is finding its way into mobile devices, protection of this asset is fast becoming a critical requirement to preserve both R&D investments and profitable revenue streams of content providers. Most content protection standards require the use of a unique numeric value stored in non-volatile technology somewhere in the system. By programming a unique key or serial number into QuickLogic CSSPs, designers can eliminate the need for specialized non-volatile memories, thereby reducing Bill-of-Materials costs and freeing up precious PCB space.
QuickLogic provides the capability of programming user-customizable, unique keys and serial identification numbers into all CSSP platforms. These keys and identification numbers conform to a customer-supplied list and can serve as the basis for a variety of content protection standards and algorithms.
Highlights
Serial ID supports
- Secure numeric ID, as long as 256 bits can be implemented in the programmable fabric of any PolarPro or ArcticLink Solution Platform
- Unique number in each CSSP device controlled by a list of desired values provided by OEM/ODM
Applications
- CE devices requiring content protection
- Data security applications
- Unique identification
