Method and secure element for attestation of trusted electronic components

The invention relates to a method and a security element for proving the plausibility of an electronic component (100), in which the security element (200) comprises a control unit (210), a recording memory (230) and a security memory (220), and in which the recording memory (230) comprises a setpoint state value (235) of the component (100), and the security memory (220) comprises a private key (226) originating from a proof (222), the security element (200) has a public key (224) of the authentication source (222), which public key can be output to a query processing unit, and the control unit (210) is designed and designed to authenticate the plausibility in order to carry out the method. The method comprises the steps of: determining an actual state value (233) of an actual state of the component (100); reading out the target state value (235) from the recording memory (230); the authenticity of the security element (200) is checked, the actual state value (233) and the target state value (235) are proces
