Abstract:
1. A method for checking the integrity of data stored in a predetermined memory area of a first device by a second device, whereby the first device is coupled to the second device by a network, the method comprising: providing a parameter for influencing a hash value calculated using a predetermined hash function; calculating the hash value on the basis of the data stored in the predetermined memory area, the predetermined hash function and the parameter, the hash value being calculated to produce a calculated hash value; and checking of the integrity of the data stored in the predetermined memory area of the first device, the integrity of the data being checked by the second device on the basis of the calculated hash value, wherein the checking includes: wherein the parameter includes a plurality of memory location pointers that define at least two memory sections of the predetermined memory area and the at least two defined memory sections cover the predetermined memory area, wherein a hash value is separately calculated for each of the at least two memory sections based on data stored in the respective memory section and the predetermined hash function, wherein the method is repeated to perform a plurality of checks of the data stored in the predetermined memory area, and a previously presented parameter is provided for each check of the data stored in the predetermined memory area.
