Introduction

Langer EMV-Technik GmbH has been offering the ICI series for fault injection into cryptographic circuits and protocols for several years. This has now been extended with the ICI-DP series. In addition to a stronger disturbance effect, the new system now also offers the possibility to generate two disturbance pulses in quick succession.

Probe Tips

In addition to the improved disturbance parameters, Langer EMV-Technik now also offers different probe tips. Tip diameters of 1000 μm, 500 μm, 250 μm, and even 150 μm are available. While the two larger probe tips (500 μm & 1000 μm) are mainly designed for attacks on encapsulated circuits, the two small probe tips (250 μm & 150 μm) allow for very precise localized fault injection into decapped circuits. The following figure shows an example of a chip with an edge length of 4 mm and a possible positioning of the different ICI-DP probe tips. The significantly increased spatial resolution of the small probe tips is clearly visible.

Tip Types

The product range of Langer EMV-Technik GmbH is completed by different tip types, i.e. the dimensions of the probe tip in relation to the housing. While the standard tip type 01 is close to the housing, tip type 02 offers more space both laterally and downwards. Tip type 03 is designed for users who require extra space at the bottom. Other customized tip types are available upon request. All tip types can also be ordered for the ICI series.
