Verfahren zum Austausch von Daten, beispielsweise von kryptographischen Schlüsseln, zwischen einem Informationssystem und einer elektronischen Einheit, wie beispielsweise einer Mikrochip-Karte

摘要

The method involves sending a certificate (CASD-CERT) associating an identifier of an electronic entity, with a public key (CASD-PK) associated with a secret key (CASD-SK) stored in the entity, from the entity towards a computer system. The association of the identifier with the public key is verified by the computer system, using the certificate. Data i.e. cryptographic keys (K1, K2, K3), are exchanged between an electronic entity application remote from a security domain, and the computer system, where the data are encoded using the public key or signed by the domain using the stored key.
