Abstract: A method for verification of configuration data which is expressive of the configuration of a computer system. A computer system having configuration data stored therein, further includes an identifier for uniquely identifying the computer system. A copy of the stored configuration data is encoded via an encoding method which uses the identifier, and the encoded configuration data is encrypted via an encryption method which uses a private key. Subsequently, the encrypted configuration data is decrypted via a decryption method using a public key producing a decrypted result. The decrypted result may either be decoded using the identifier and compared to the stored configuration data or alternatively the stored configuration data may be encoded using the identifier and compared to the decrypted result.
