FortiMac library – Advanced HMAC SHA2 DPA- and FIA-Resistant Software Library


The FortiMac library belongs to the FortiMac product family. This software library provides ultra-strong protection against SCA, FIA, and cache attacks.

This is the only pure SW solution in the market.

The underlying protection is purely algorithmic and implementation-agnostic. Resistance to attacks was validated analytically and on a physical device. The protection is based on the Threshold Implementation (TI) approach, the security of which has been proven.
