Supplemental Biometric User Authentication for Digital-Signature Smart Cards

: This paper specifies how biometric verification methods can be applied in addition to PIN verification on digital-signature smart cards in compliance with established smart-card standards. After successful PIN verification, multiple digital signatures can be created; each signature creation, however, is preceded by biometric verification. 1 Motivation Tamper-resistant, personal smart cards are used for the secure storage of private signature keys and as protected environment for the creation of digital signatures [DIN V 66291-1, Pie08, EN 14890-1]. For checking the access rights on the protected functions of a digital-signature smart card, also biometric features of the cardholder can be used in addition, or as alternative, to a secret PIN (personal identification number). The strengths of biometric methods lie in their relative ease of use. If sufficiently resistant against direct and indirect attacks, biometric user authentication methods can strengthen the binding of digital signa...
