Abstract
A method of authenticating sensor data includes receiving, by at least a temporal attester, sensor data, calculating, by the at least a temporal attester, a current time, generating, by the at least a temporal attester, a secure timestamp generated as a function of the current time, and transmitting, by the at least a temporal attester and to at least a verifier, a temporally attested sensor signal including the secure timestamp.
Claims20
A system for signal localization and verification of sensor data, the system comprising:
- a temporal attestor, the temporal attestor comprising:
- a processor configured to:
- receive sensor data;
- calculate a current time;
- generate a secure timestamp generated as a function of the current time;
- and
- transmit a temporally attested sensor signal including the secure timestamp and the sensor data;
- and
- a temporal verifier, the temporal verifier comprising:
- a processor configured to:
- receive, from the temporal attestor, the temporally attested sensor signal including the secure time stamp;
- verify the secure time stamp;
- and
- determine, as a function of the secure time stamp, an authenticity of the temporally attested sensor signal, wherein the determining the authenticity of the temporally attested sensor signal comprises:
- comparing the secure time stamp to a reference time, the comparing the secure time stamp to the reference time comprising:
- calculating, by the temporal verifier, a network latency;
- calculating, by the temporal verifier, an expected transmission time of the temporally attested sensor signal based on the network latency;
- comparing the expected transmission time and a threshold amount of time beyond the expected transmission time;
- and
- determining the authenticity of the temporally attested sensor signal based on the comparison of the expected transmission time and the threshold amount of time beyond the expected transmission time.
