Abstract
A method for replacing the operating software of a limited-resource portable data carrier at a terminal includes controlling the operation of the data carrier and executing at least one function provided by the data carrier. The terminal includes new operating software, a bootstrap loader for loading new operating software, and a terminal certificate providing authorization for transmitting a loading key. In authentication of the terminal, the terminal certificate is transmitted to the data carrier and verified there and a loading key is transmitted to the data carrier. The operation control of the data carrier changes over to the bootstrap loader which deletes the present operating software of the data carrier and transmits the new operating software using the loading key from the terminal. The new operating software is then verified and activated by the bootstrap loader which transfers the control of the data carrier to the new operating software.
