Abstract

Method and apparatus for securely transporting data onto an IC card. The method is used, for example, to transport data, including application programs, in a secure manner from a source located outside the IC card. At least a portion of the data is encrypted using the public key of a public/secret key pair of the intended IC card unit. The encrypted data is then sent to the IC card and the IC card verifies the key transformation unit using its unique secret key. The data can then be stored on the IC card. A copy of the public key signed by a certification authority can be used to verify that the card is authorized to be part of the overall authorized system.
