Abstract
A method and an apparatus for multipath authentication are described. A card reader and an application executed thereon interact with a chip card. This results in a request being transmitted to the chip card. The chip card provides an identifier, e.g. a random number. The card reader initiates an attestation of the application by an attestation authority and transfers an attestation response and the identifier to a service that is to be used. The service verifies the attestation response and signs the identifier if the attestation response is valid. The signed identifier is then transferred to the card reader, which in turn transfers the signed identifier to the chip card. The chip card can then check whether the signed identifier is valid. If the signed identifier is valid, the chip card provides the application with other functions.
