LEIA is an open hardware and open source device designed for educational, research and security assessment purposes. LEIA allows you to perform everything from side-channel analysis (SCA) and glitching attacks to full-functional smart card/USIM reading. LEIA offers a standalone mode as well as a ChipWhisperer mode. It implements a fully controlled ISO7816 stack with a dedicated custom hardware platform to acquire clean measurements for SCA characterization.

Smart card communication

  • Hardware based ISO7816 stack supporting both ISO7816-3 T=0 and ISO7816-3 T=1
  • Bitbanged ISO7816 stack allowing to fully control the communication
  • Timing measurement between ISO7816 transactions
  • PTS negotiation (flexible ETU selection)
  • ISO7816 clock frequency tuning

All the code used for smart card communication is opensourced. This includes both the ISO7816 stack used by the LEIA Firmware and the smartleia command and control interface developed in Python.

 

Triggering

Up to 4 trigger strategies, each one on 10 possible trigger events corresponding to classical ISO7816 events (beginning of ATR, end of ATR, sending an APDU and receiving a response, etc.).

 

  • The triggers also have a configurable delay, and support a ‘single’ mode.
  • All the triggers states (number of observed triggers, etc.) can be recovered.
  • Dedicated trigger pin in SOLO mode (standalone mode).
  • ChipWhisperer triggering through the 20-pins standard interface.

All the code used for smartcard communication is opensourced. This includes both the Trigger strategies firmware implementation and the smartleia interface.

 

Power analysis and glitching

In both SOLO and ChipWhisperer modes:

  • USB-powered mode with optocouplers for more efficient measurements.
  • Direct power mode (external controlled power supply not delivered).

 

Smart card reader mode

Fully integrated with PC/SC, which allows to use LEIA as a classical smart card reader.
