An integrated circuit including an electronic fuse for supporting a secure bootstrap process, in which the fuse is queried. The circuit includes a protection against electromagnetic fault injection. The circuit is configured in such a way that the protection extends to the bootstrap process.

Integrated circuit and embedded system including such an integrated circuit with bootstrap configuration for attack prevention

A method for processing data includes coding a data item to obtain a coded data item that includes a predefinable number of bits, influencing maximally k many bits of the coded data item to obtain a changed data item, decoding the changed data item by using a fault-correcting code to obtain a decoded data item, and processing the decoded data item.

Method and device for processing data

A method for providing a computer program for a computing unit of an electronic device, in particular a control device of a motor vehicle or of a household appliance, wherein the method includes: evaluation of properties of the electronic device relating to a susceptibility to side channel attacks and/or fault attacks, as a result of which an evaluation result is obtained, selection of at least one influencing parameter that has an influence on the susceptibility of the electronic device to side channel attacks and/or fault attacks, in particular as a function of the evaluation result, use of the at least one influencing parameter to diversify the computer program for the computing unit.

Method and device for providing a computer program

A method for safeguarding a system-on-a-chip includes a hardware-programmable logic unit. In the course of a programming process, a public PUF key and a private PUF key are generated in the hardware-programmable logic unit with the aid of a physical unclonable function, and the public PUF key is signed with the aid of a second private key. The public PUF key and its signature are stored in an external memory of the system-on-a-chip, a security module is signed with the aid of a third private key, the security module and its signature are stored in the external memory of the system-on-a-chip, and the security module includes software which is used for safeguarding the system-on-a-chip.

Method for safeguarding a system-on-a-chip

A symmetrical iterated block encryption method includes: a bitwise XOR combination of a predetermined data word of a predetermined block with a predetermined data word of a predetermined round key; and a bitwise XOR combination of the predetermined data word with at least one other predetermined data word.
