Abstract (en)
[origin: WO2007088288A1] The invention concerns an authenticating method including: a step of generating a random number (105); a step of generating a timestamping (115); a step of generating a first secret key (120); a step of truncating a message authentication code using said first secret key (125); a step of symmetrically encrypting the random number, the timestamping and the truncation (135), using a second secret key (130) to produce an authentication code (145). Preferably, during the step of generating the random number, a quantum generator (100) is used. Preferably, during the truncating step, a cryptographic message authenticator is generated using the first secret key. Preferably, during the step of symmetrically encrypting the random secret key, using the second secret key, a message digest (140) is additionally produced.
