Systems, devices, and methods for recording a digitally signed assertion using an authorization token
A system for recording a digitally signed assertion using an authorization token, includes a cryptographic evaluator designed and configured to receive a dataset and an authorization token. The authorization token includes a verification datum of a device-specific secret possessed by the cryptographic evaluator, a digital signature of a certificate authority generating the authorization token, and a secure temporal attribute. The cryptographic evaluator is configured to produce a secure proof using the device-specific secret. The cryptographic evaluator is configured to generate a first digitally signed assertion as a function of the dataset, the secure proof, and the authorization token. The cryptographic evaluator is configured to enter the first digitally signed assertion in at least an instance of a first temporally sequential listing.
