The invention relates to a method for authenticating a portable data carrier (10) with regard to a communication device. Once the data carrier (10) has received an authentication request from a communication device (200), the data carrier evaluates (300) the reliability of the authentication request and rejects (400, 500) the authentication request unless the data carrier (10) has evaluated it as being reliable. Otherwise, the data carrier (10) transmits an authentication answer (400, 510) in reply to the authentication request to the communication device, the reliability of the authentication request being evaluated using a relational information and/or an identification information of the communication device which information was received by the data carrier (10).
