Abstract
A method is disclosed of a secure component (SC) of a local attestation server (LAS) for populating an enclave associated with the LAS. The SC comprises stored encrypted population information previously received in a data packet and encrypted by an encryption key matching a private decryption key of a trusted platform module (TPM) associated with the LAS. The method comprises receiving a public part of a temporary asymmetric key from the enclave, establishing a secure session between the SC and the TPM, sending (to the TPM by using the secure session) the encrypted population information and the public part of the temporary asymmetric key, receiving (from the TPM by using the secure session) the population information decrypted by the private decryption key and re-encrypted by the public part of the temporary asymmetric key, and transmitting the re-encrypted population information to the enclave. An additional method is also disclosed for enabling the population of the enclave. The additional method comprises receiving control parameters of the LAS, comprising the encryption key matching the private decryption key of the TPM, encrypting population information based on the control parameters and using the encryption key, and sending a data packet comprising the encrypted population information to the SC. Corresponding apparatuses and computer program product are also disclosed.
