CryptoFirewall Cores Solution Overview

Download “CryptoFirewall Cores Solution Overview ”

Designed to prevent tampering, the hardware-based CryptoFirewall™ security core minimizes the risk of security failure and helps simplify product development. Comprising a security boundary inside a chip, the core stores private keys and maintains security – even if the rest of the system is compromised. CryptoFirewall solutions complement existing security implementations and are ideal for a wide range of applications, including digital entertainment, electronic devices, printers and ink toners. Our CryptoFirewall line-up includes cores for protecting digital entertainment and preventing counterfeiting.

The advancing capabilities of attackers are driving a new phase in Pay TV signal piracy: pairing keys and control words can be extracted from set-top box (STB) chipsets. These attacks defeat the current defenses against control word sharing and provide access to plaintext control words, enabling illegal access to premium content by non-subscribers. Solving the problem requires improved security in device chipsets, or System-on-Chips (SoCs), including strong hardware security cores.

Securing OTT Content with CryptoFirewall Security Cores

Today, content protection in connected devices such as tablets and smart TVs is predominantly provided by software security. The level of protection achievable in software on these platforms today does not meet the latest studio requirements for premium content. In order to provide stronger security while simplifying product development, system-on-chips (SoCs) used in Internet-enabled televisions and mobile devices have started to include integrated hardware security cores. Once designed into an SoC, these hardware security cores provide a significant increase in security without sacrificing user-friendliness, flexibility or cost. The CryptoFirewall core is the leading hardware security core for TV/video distribution. It is designed to provide the multioperator flexibility and robust security required for Over-the-Top (OTT) multi-screen distribution to connected devices.

Is Your Mobile Device Radiating Keys?

Is your mobile device’s EM emissions leaking your keys? A mobile app can inadvertently radiate secret data as cryptographic processing is done by the CPU. We’ll use a simple antenna and radio to perform live key extraction from several modern handheld devices. Developers can use several techniques to mitigate risk whenever applications use high-valued cryptographic keys.

Efficient sidechannel testing for public key algorithms: RSA case study

This paper proposes an approach to validate that implementations of public‐key cryptography have moderate resistance to side‐channel analysis, using RSA‐CRT as an example. The design goal of the proposed approach is to develop tests that are technically sound and repeatable, while at the same time being efficient and cost‐effective for testing labs. The approach was validated on two devices, one without countermeasures and another with some DPA countermeasures.
