An electronic device for processing data includes: an input interface for receiving input data; a processing module for processing data; and an encoding unit configured to encode data words received at the input interface as input data, in order to obtain encoded data words. The encoding unit is configured to encode the data words in such a manner that a specified proportion of all encoded data words have a specified Hamming distance and/or a specified Hamming weight. The processing module is configured to process the encoded data words.

A method for the manipulation-proof transmission of data from a transmitter to a receiver, a test part being generated in the transmitter from the data using a secret key and communicated together with the data to the receiver, where a verification test part is generated from the received data using the same secret key and is compared to the received test part. Before the generation of the test part, the data are nonlinearly compressed using at least one feedback shift register. In addition, a device for the manipulation-proof transmission of data.

A method and a random bit generator for generating a random output bit sequence. In this method, a configuration of 2n state machines is used, the state machines each including n state bits, each state machine always assuming a different state than the other state machines of the configuration, an input signal being supplied to the input end of the state machines, and these each generating n signature bits, which together form a signature bit sequence, as a function of their state, the random output bit sequence being generated by selection of individual bits from the signature bit sequences of all state machines of the configuration.
