Embedded Security for Flash Memory

CryptoFlash is a complete security platform for mobile storage devices such as: flash cards, USB flash drives, and embedded flash memory.

It offers an outstanding level of security, while overcoming the challenges of:

Performance
Power consumption
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.

Embedded Flash Security Components

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:

Side channel attacks
Timing attacks
Fault analysis
Simple power analysis
Differential power analysis

These countermeasures span across all layers of the solution architecture.
