The inventive method consists in transmitting a first digital channel (X<SUB>0</SUB>) from a reader to a marker, in receiving on the marker a second digital channel (Y<SUB>o</SUB>) corresponding to the first digital channel and to errors introduced by a near noisy channel, in introducing artificial errors into at least one of the first or second digital channels, in carrying out an advantage distillation phase in such a way that a new first digital channel (X<SUB>1</SUB>) is determined for the reader and a new second digital channel (Y<SUB>1</SUB>) is determined for the marker in such a way that the advantage is taken with respect to a possible passive attacker, in carrying out an information reconciliation phase, wherein an error-correcting protocol is applied to the new first (X<SUB>2</SUB>) and new second (Y<SUB>2</SUB>) digital channel and in carrying out a secrecy amplification phase, wherein a hash function (G) is applied to the new first (X<SUB>2</SUB>*) and the new second (Y<SUB>2</SUB>*) digital channel |
