Robust Security Against Side Channel Attacks
The security core is embedded in the STB multimedia chipset, and provides robust hardware-based security to complement CAS and DRM software. The core features integrated resistance to side-channel attacks, such as simple power analysis (SPA) and differential power analysis (DPA), further enhancing the protection of high-value content. The CryptoMedia Content Protection Core is an added layer of security that works with existing chipset security features, such as:
- Key ladders (including the shareable ETSI key ladder)
- Dedicated multi-tasking security CPUs or Trusted Execution Environments (TEEs)
- Specific hardware security blocks
- Secure video paths.
By enabling all of the security options available in a CryptoMedia-enabled STB multimedia chipset, content providers can expand beyond a single chain of security to several parallel security chains, providing the highest level of protection at a lower price than smart cards.
