Systems, apparatus and methods for privacy-protecting integrity attestation of a computing platform. An example method for privacy-protecting integrity attestation of a computing platform (P) has a trusted platform module (TPM}, and comprises the following steps. First, the computing platform (P) receives configuration values (PCRI . . . PCRn). Then, by means of the trusted platform module (TPM}, a configuration value (PCRp) is determined which depends on the configuration of the computing platform (P). In a further step the configuration value (PCRp) is signed by means of the trusted platform module. Finally, in the event that the configuration value (PCRp) is one of the received configuration values (PCRI . . . PCRn), the computing platform (P) proves to a verifier (V) that it knows the signature (sign(PCRp}} on one of the received configuration values (PCRI . . . PCRn).
