Abstract (en)
[origin: WO2020200729A1] The invention claims a method for configuring a security module (SD) with at least one derived key, having the following steps: - providing a key (MK); - deriving (KDF) a further key (K1 to KN) from the provided key or from a key previously derived from the provided key, characterized in that said further key is derived by using an alterable digital fingerprint (FP) as key derivation parameter, which is formed on the basis of a measurable current runtime configuration of a runtime environment (R) communicating with the security module.
