FortiMac is a cutting-edge IP core solution that delivers a secure implementation of HMAC SHA2 that provides ultra-strong protection against SCA and FIA using a very low number of standard digital gates. The protection method is based on the Threshold Implementation (TI) paradigm; thus it provides a robust protection against side channel (SC) and fault injection (FI) attacks. Resistance to attacks was validated analytically and on a physical device. FortiMac stands as the only solution of its kind in the market.
