Methods and systems for efficient cryptographic third-party authentication of asset transfers using trusted computing
A system for efficient third-party authentication of asset transfers using trusted computing includes a process authentication node configured to receive transfer data relating to an asset transfer, wherein the transfer data includes at least a first authentication datum, retrieve, from an instance of a secure listing, a first digitally signed assertion including at least a second authentication datum, wherein the first digitally signed assertion is generated by a data validator device as a function of information of a transferring entity, compare the at least a first authentication datum to the at least a second authentication datum, and authenticate the transfer data as a function of the comparing of the at least a first authentication datum to the at least a second authentication datum.
1. A method of efficient cryptographic third-party authentication of an asset transfer, the method comprising:
receiving, at a process authentication node, transfer data relating to an asset transfer, wherein the transfer data includes at least a first authentication datum, and wherein the first authentication datum includes an authorization token;
retrieving, by the process authentication node, from an instance of a secure listing, a first digitally signed assertion including at least a second authentication datum, wherein the first digitally signed assertion is generated by a data validator device as a function of information of a transferring entity;
comparing, by the process authentication node, the at least a first authentication datum to the at least a second authentication datum wherein comparing the at least a first authentication datum to the at least a second authentication datum further comprises retrieving the at least a second authentication datum from a locally stored instance of the secure listing; and
authenticating, by the process authentication node, the transfer data as a function of the comparing of the at least a first authentication datum to the at least a second authentication datum, wherein the process authentication node includes a physically unclonable function (PUF).
2. The method of claim 1 further comprising receiving a secure proof associated with the transferring entity.
3. The method of claim 1 , wherein the first digitally signed assertion identifies the data validator device.
4. The method of claim 3 , wherein the first digitally signed assertion is generated by the data validator device using trusted hardware.
5. The method of claim 1 further comprising determining a confidence level in the data validator device.
6. The method of claim 5 , wherein determining the confidence level further comprises cryptographically validating a secure timestamp.
7. The method of claim 1 , wherein the process authentication node and the data validator device are not connected by a network.
8. The method of claim 1 further comprising cryptographically validating freshness of a local copy of the secure listing.
9. The method of claim 1 , wherein the at least a second authentication datum further comprises a cryptographic hash of authentication information, and comparing the at least a first authentication datum to the at least a second authentication datum further comprises cryptographically hashing the at least a first authentication datum.
10. A system for efficient third-party authentication of asset transfers using trusted computing, the system including a process authentication node, the process authentication node including a processor, the process authentication node configured to:
receive transfer data relating to an asset transfer, wherein the transfer data includes at least a first authentication datum, and wherein the first authentication datum includes an authorization token;
retrieve, from an instance of a secure listing, a first digitally signed assertion including at least a second authentication datum, wherein the first digitally signed assertion is generated by a data validator device as a function of information of a transferring entity;
compare the at least a first authentication datum to the at least a second authentication datum, wherein comparing the at least a first authentication datum to the at least a second authentication datum further comprises retrieving the at least a second authentication datum from a locally stored instance of the secure listing; and
authenticate the transfer data as a function of the comparing of the at least a first authentication datum to the at least a second authentication datum, wherein the process authentication node includes a physically unclonable function (PUF).
11. The system of claim 10 , wherein the process authentication node is further configured to receive a secure proof associated with the transferring entity.
12. The system of claim 10 , wherein the first digitally signed assertion identifies the data validator device.
13. The system of claim 12 , wherein the first digitally signed assertion is generated by the data validator device using trusted hardware.
14. The system of claim 10 , wherein the process authentication node is further configured to determine a confidence level in the data validator device.
15. The system of claim 14 , wherein determining the confidence level further comprises cryptographically validating a secure timestamp.
16. The system of claim 10 , wherein the process authentication node and the data validator device are not connected by a network.
17. The system of claim 10 wherein the process authentication node is further configured to cryptographically validate freshness of a local copy of the secure listing.
18. The system of claim 10 , wherein the at least a second authentication datum further comprises a cryptographic hash of authentication information, and comparing the at least a first authentication datum to the at least a second authentication datum further comprises cryptographically hashing the at least a first authentication datum.
