摘要
The invention relates to a method for the authentication of a first electronic entity (C) by a second electronic entity (H). The first electronic entity (C) implements the following steps: reception of a challenge (HCH) from the second electronic entity (H); generation of a number (CCH) according to a current value of a counter (SQC) and a first secret key (K-ENC); generation of a cryptogram (CAC) according to the challenge (HCH) and a second secret key (S-MAC); and transmission of a response including the cryptogram (CAC) to the second electronic entity (H), without transmission of said number (CCH).
