Abstract: In one embodiment, the method includes computing composite cryptographic data by executing a plurality of first cryptographic algorithms, wherein the composite cryptographic data are computed as a function of input data, wherein the plurality of first cryptographic algorithms are selected and/or the plurality of first cryptographic algorithms are combined according to a first control algorithm; computing results data using a receiver cryptosystem as a function of the composite cryptographic data by applying one or more of the second cryptographic algorithms, wherein the one or more second cryptographic algorithms are selected and/or combined according to a second control algorithm; and automatically executing a software and/or hardware function using the receiver cryptosystem according to the results data.

Abstract: The method includes authenticating a chip card terminal to a chip card by a chip card operating system, verifying the authorization of the chip card terminal to load executable program instructions by the chip card operating system, storing data in a predefined memory region of the NVM, which data indicate a successful execution of the authentication and the verification, by the chip card operating system, starting execution of a boot loader by the chip card operating system and interrupting the execution of the chip card operating system following the start of the boot loader, reading the data from the predefined memory region by the boot loader, loading the program instructions from the chip card terminal into the NVM by the boot loader on the precondition that the data indicate the successful authentication and verification in the predefined memory region.

Abstract: The invention relates to a method for generating a certificate for signing electronic documents by means of an ID token (106), having the following steps: —sending (201) a transaction request for a user to carry out a transaction, —as a result of the sending of the transaction request, a check is carried out as to whether the certificate (519) is available and if this is not the case, carrying out the following steps: generating (206) an asymmetrical key pair consisting of a private key and a public key using an ID token, said ID token (106) being assigned to the user; storing (207) the generated asymmetrical key pair on the ID token, wherein at least the private key is stored in a protected memory region of the ID token; transmitting (208; 509) the generated public key (518) to a first computer system, and generating (209) the certificate (519) by means of the first computer system for the public key.
