Abstract

Claims (16)

1 . A system for utilizing a computer-readable tamper-evident log to manage an action to be performed by at least one computing device, the tamper-evident log accessible via at least one network interface that is communicatively coupled to a communications network, the system comprising:

one or more processors configured to:

generate an attestation value for the action with a cryptographic digital signature function;

transmit information about the action to at least one node on the network, the information corresponding to the attestation value; and

a memory, coupled to the one or more processors, for storing computer program instructions to be executed by the one or more processors;

wherein:

before the action is allowed to be performed, the tamper-evident log is updated by appending the information about the action to the tamper-evident log, the attestation value based at least in part on the action to be performed;

after the information about the action has been appended to the tamper-evident log, the action is caused to be performed; and

tampering of the tamper-evident log is detectable by performing a verification using the information about the action and the attestation value for the action.

2 . The system of claim 1 , wherein:

the one or more processors are further configured to:

generate with the cryptographic digital signature function an other attestation value for an other action, and

transmit information about the other action to at least one other node on the network, the information about the other action corresponding to the other attestation value; and

before the other action is allowed to be performed, the tamper-evident log is updated by appending the information about the other action to the tamper-evident log, the other attestation value based at least in part on the other action to be performed;

after the information about the other action has been appended to the tamper-evident log, the other action is caused to be performed; and

tampering of the tamper-evident log is detectable by performing an other verification using the information about the other action and the other attestation value.
