摘要：
Described is a mechanism for securely handling an information unit by a first information processing device (2), for instance a terminal device like a chip card reader, which interoperates with a second secure information processing device (1), for instance a portable device like a chip card, whereby the information unit is provided by an issuer. The information unit is provided from the issuer to the first device and encrypted by using a first key. The first key is also encrypted by using a second key. The second key is provided on the second secure device (1) and interconnecting the first and the second device enables to decrypt the first key by using the second key and then to decrypt the information unit by using the first key.
