Embedded Security for Flash Memory

CryptoFlash is a complete security platform for mobile storage devices such as Flash cards, USB Flash drives, embedded Flash memory, high capacity SIM cards, and hard disk drives. It offers an outstanding level of security, while overcoming the challenges of performance, power consumption and silicon footprint. CryptoFlash’s flexible architecture offers semiconductor vendors and device manufacturers a robust solution that can be tailored to meet today’s demanding mobile security requirements.

Countering Threats, Securing Opportunities

CryptoFlash is a driving force behind the expansion of Flash memory into new markets and applications. New applications ranging from preloaded content to wireless telephony are exposing the device and its contents to a host of new opportunities and threats. CryptoFlash provides the necessary security foundation for the ongoing development of the market.

Integrated Architecture – Robust Protection

CryptoFlash’s multi-layered architecture ensures all components of the device and its applications are secure. Discretix has registered multiple patents for the implementation of cryptographic algorithms in a way that minimizes gate count and power consumption while maximizing performance and security.

Applications & Toolkits Layer

Essential toolkits for secure implementation of applications such as Digital Rights Management, Device Management and Secure Authentication.
System Security Middleware Layer

A suite of software modules including APIs and security protocols and services to reduce time-to-market and ease integration.
Enables secure access to the low level cryptographic functions, algorithms and the Random Number Generator. Implementation requires a minimum amount of code and run-time memory.
Hardware Core Layer

The hardware layer is delivered as IP for easy integration into ICs. Discretix patented technology implements the 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:

  • Physical probing
  • Side channel attacks
  • Timing attacks
  • Fault analysis
  • Simple power analysis
  • Differential power analysis
  • Power consumption balancing
  • Fixed time-per-operation
    (operand agnostic)

These countermeasures span across all layers of the solution architecture.
