The CryptoFirewall™ Transport Core is a separate, on-chip, hardware-based security block that secures digital entertainment content by protecting cryptographic keys and computations from attack. Available on leading set-top-box ( STB) SoCs, the CryptoFirewall Transport core provides a robust foundation for conditional access systems that maintains security even if the software and other cryptographic logic on the chipset are compromised.
- Protects against a broad range of attacks including: Software bugs
- Reverse engineering
- Glitching/fault induction
- Power analysis (SPA/DPA)
- Control word sharing
- Protocol attacks
- Focused ion beam analysis
- Cost-effective security in the SoC - no external interface to attack
- Provides the strongest hardware protection
- Complements both software and smart card CA and DRM systems
- Supports all major content distribution platforms - Satellite, cable, IPTV, OTT, physical media
- Meets studio security requirements, facilitating licensing of premium content
- Integrates easily; reference implementations and services available as needed
- Strong, cost-effective security for pay TV and digital entertainment
- Includes complete key management with dedicated high-security root key storage on the STB chip
- Meets operator and studio security requirements
- Supports all main distribution formats – satellite, cable, IPTV, and OTT
- Integrates with leading CAS and DRM systems
- Gate-level netlist targeted to vendor-specified cell library
- Full technical documentation: Interface specifications
- Integration guides
- Validation guides
- Manufacturing test and personalization specs
- Test and Verification: Verification models
- Emulation boards
- Functional verification tests
- System and validation tests
- Under the CryptoFirewall™ program, the Cryptography Research division of Rambus can manage all aspects of the engineering process, including complete circuit design and integration with existing conditional access and hardware vendors.
- The CryptoFirewall security core utilizes standard chip manufacturing processes. Our engineering team has worked closely with leading chip manufacturers to integrate the CryptoFirewall security core into transport chips used in set-top boxes, removable smart cards used by leading conditional access providers, and stand-alone ASICs.
- Pay television operators typically coordinate with their conditional access vendor and Cryptography Research to determine whether a standard or custom CryptoFirewall security core is most appropriate for their system.
