Abstract (en)

[origin: WO2014037075A1] The invention relates to a method for authenticating a portable data carrier with respect to a terminal device using a public key and a private key of the original data carrier and using a public session key and a private session key of the terminal device. For said authentication, the data carrier uses a public group key as the public key and a key which is derived from a private group key associated with the public group key as the private key, said derivation being achieved using a derivation parameter. The portable data carrier uses the private group key to generate a digital signature of a data element which is required for the authentication process and into which the derivation parameter is integrated.
