Discretix CryptoCell®

cp_CC_picA Trusted Environment

CryptoCell is a complete embedded security platform for mobile phones, portable devices, automotive controllers and embedded systems where a strong security infrastructure is called for. CryptoCell provides an outstanding level of security, while overcoming the challenges of performance, power consumption and silicon footprint. Its flexible architecture offers semiconductor vendors and device manufacturers a robust solution that can be tailored to meet today’s demanding embedded security requirements. CryptoCell can be deployed across multiple platforms and operating systems to secure a broad range of applications.

As the computing power of embedded devices increases, data applications and services are seen as the major catalyst for revenue generation. Discretix pioneered embedded security to enable applications and protect this new generation of embedded devices from a growing range of threats.

Integrated Architecture – Robust Protection

CryptoCellComple 

The CryptoCell platform is deployed as an integral part of the device to deliver the highest level of security and performance. The solution’s multi-layered architecture ensures that all components of the device and its applications are secured. CryptoCell is delivered as a tested and ready-to-implement platform.

 

Applications & System   Essential security components for applications such as DRM, CAS, Software Update, SIM Lock, as well as security system features such as secure boot and secure debug.
     
Security Middleware Layer  

The security middleware layer provides secure access to the hardware and serves as a robust security services infrastructure for the application layer. It provides secure storage, cryptographic schemes, key management, certificate management and others across multiple platforms and operating systems.

The secure boot mechanism supports different stages in the device life cycle and completes the system security solution.
     
Hardware Core Layer  

The hardware layer is delivered as IP for easy integration into ICs. Discretix patented technology provides a secure execution environment as well as implements standardized cryptographic algorithms in a way that minimizes gate count and power consumption while maximizing performance and security.
Attack-Resistant
Cryptographic Core
 

Discretix deploys unique and patented mechanisms to provide robust protection against:

  • Timing Attacks (TA)
  • Fault Attacks (FA)
  • Power Analysis

Robust countermeasures span across all layers of the solution architecture.

CryptoCell is delivered as a tested and ready-to-implement platform.
