The object of the invention is in particular the validation of configuration of a system comprising a plurality of elements, at least one reference being associated with each element of the said plurality of elements. After at least one reference key has been calculated (410) according to at least one expected reference of each element of the said plurality of elements, a theoretical configuration report of the said system, comprising the said at least one reference key, is generated (420). Similarly, at least one verification key is calculated (455) according to at least one reference of each element of the said plurality of elements, and a real configuration report of the said system, comprising the said at least one verification key, is generated (460). A configuration error is detected if the values of the said verification key and reference key of the said real and theoretical configuration reports are different.
