Abstract
The invention relates to a method and a secure element for detecting the trustworthiness of an electronic assembly (). The secure element () comprises a control unit (), a record storage device (), and a secure storage device (); the record storage device () comprises a target state value () of the assembly (); the secure storage device () comprises a private key () of a proof of origin (); the secure element () has a public key () of the proof of origin (), said public key being output to a requesting processing unit; and the control unit () is designed to carry out the method in order to detect the trustworthiness. The method has the steps of ascertaining an actual state value () of the actual state of the assembly (), reading the target state value () from the record storage device (), verifying the authenticity of the secure element (), processing the actual state value () and the target state value (), and deciding whether the actual state is sufficiently similar to or compatible with or matches the target state such that a trust criterion is satisfied.
