Project TitleFlash Memory for Ubiquitous Hardware Security Functions: True Random Number Generation and Device Fingerprints
Track Code5920
Short Description

The invention is a method to enable important security functions in flash memory devices without requiring any hardware change.

Abstract

Exploiting certain noise characteristics that exist in all off-the shelf flash memory devices, high quality random number generation at a rate up to 10Kbits/second was demonstrated. Furthermore, many unique digital fingerprints useful for identification and authentication are generated based on a scheme that utilizes process variations. Using these techniques, such security functions can be easily enabled by a firmware update or software change in existing devices.

 

Potential Applications:

Security for electronic devices with floating-gate, non-volatile memory, such as:

  • Mobile devices, e.g., smartphones, tablets, etc.
  • Next-generation laptop and desktop computers
  • Stand-alone flash memory, e.g. USB memory sticks, SD cards

 

Advantages:

  • Easy to implement: no additional hardware or changes to flash chips or interfaces required
  • Fast, high-quality security features
