What is ChipWhisperer?

ChipWhisperer focuses on power analysis, which uses information leaked by a device’s power consumption to mount an attack, as well as voltage and clock glitching attacks, which briefly disrupt a device’s power or clock to cause unintended behaviour (such as skipping a password check).

​

Hardware

ChipWhisperer is your embedded security multitool. Features like synchronous capture make it great for  power analysis, which uses information leaked by a device’s power consumption to recover encrypted data. ChipWhisperer also has many features for voltage and clock glitching attacks, which briefly disrupt a device’s power or clock to cause unintended behaviour like instruction skipping.

Firmware

A range of capture boards are available from the HuskyPlus to the CWNano, letting you get the features you need at a price you can afford. NewAE targets let you experiment on common microcontrollers and security implementations without cracking open consumer devices.

Software

ChipWhisperer software is a collection of open source Python code that makes it easy to get started with embedded security. The ChipWhisperer Capture API streamlines interfacing with the hardware over USB, while the ChipWhisperer Analyzer library provides functions and structures for running analysis on captured data.

  • Sample Rate & ADC: 200 MS/s, 12-bit

  • Sample Buffer Size: > 80 KSample

  • Streaming Support (limited by computer buffer): >20 MS/s, 8-bit data can stream back for unlimited capture sizes.

  • Voltage Glitching: 2-size Crowbar glitch

  • Clock Glitching: High resolution glitch generation based on phase-shift architecture (sub nS resolution)

  • I/O Pins: ChipWhisperer 20-pin header, additional 8 data + 1 clock line. All I/O pins 3.3 V.

  • FPGA: Artix A35
