METHOD FOR SAFEGUARDING THE INFORMATION SECURITY OF DATA TRANSMITTED VIA A DATA BUS AND DATA BUS SYSTEM

A method for saving the information security of data transmitted by a databus, in which the data to be transmitted via the databus from a transmitter (ECUs) to at least one receiver (ECUR) are divided into data blocks (M0 . . . Mn) before being sent off, wherein the data blocks (M0 . . . Mn) are enc...

Zusammenfassung:	A method for saving the information security of data transmitted by a databus, in which the data to be transmitted via the databus from a transmitter (ECUs) to at least one receiver (ECUR) are divided into data blocks (M0 . . . Mn) before being sent off, wherein the data blocks (M0 . . . Mn) are encrypted and/or signed block by block by means of a sponge construction for forming a cryptological hash function, utilizing a key, and cipher blocks (C0 . . . Cn) generated in this way are transmitted via the databus to the at least one receiver. The invention also relates to a corresponding databus system.
