AUTOMATED ATTESTATION OF DEVICE INTEGRITY USING THE BLOCK CHAIN

摘要

Systems and methods are disclosed that provide for a full validation of an unknown client device prior to acceptance of a block chain transaction would provide further security for block chain transactions. The health of the device can be attested to prior to engaging in electronic transactions. In some embodiments, automation of full device integrity verification is provided as part of a block chain transaction. Certain aspects of the invention enable trust in devices. Some embodiments operate on the fundamental premise that a reliable relationship with a device can make for a much safer, easier and stronger relationship with an end user. Achieving this requires knowing with confidence that a device involved in a current transaction is the same device it was in previous transactions.

主权项

1. A computer-implemented method of verifying device integrity of a user device in a block chain communication network comprising:
in preparation for delivering an electronic transaction in the block chain network, implementing a device integrity verification process as part of the transaction including:
performing an internal validation of the integrity of the device execution environment from a root of trust in the user device; andrequiring an electronic signature, such that a verification of the integrity of the signature is applied to the block chain transaction,the verification of the integrity of the signature being based on a determination of whether the execution environment of the device is in a known good condition including
based on the integrity of the signature, allowing the transaction to proceed or requesting a remediation authority to verify that the electronic transaction as intended by the user is allowed to proceed even if it is determined that the execution environment of the device is not in a known good condition.
