Abstract (en)
[origin: WO2023030811A1] The invention relates to a method for implementing and using cryptographic material (KM) in at least one system component (SK) of an information technology system (IT-S) for performing at least one operation, wherein a state of the system component (SK) as described by at least one variable (VAR) is checked at least at a first time, the cryptographic material (KM) is supplemented with additional data, wherein the additional data describe possible states of system components (SK), and the cryptographic material (KM) is used by the system component (SK) when the additional data of the cryptographic material (KM) comprise at least the state that the system component (SK) has at the first time. The method according to the invention is characterized in that the additional data are formed by at least one condition (BED, BEDKM*, BEDKM Prov, BEDKM Type(skid), BEDKM Type(skid), Prov), at least one role (ROLEKM*) and/or at least one target component identity (ZKIDENTKM).
