US Patent 11784809 Constrained key derivation in temporal space

The technology disclosed herein provides an enhanced cryptographic access control mechanism that uses cryptographic keys that are based on temporal data. An example method may include: determining temporal data of a computing device; transforming the temporal data in view of conversion data associated with the computing device, wherein the conversion data causes a set of alternate temporal data values to transform to a specific cryptographic value; creating, by a processing device, a cryptographic key in view of the transformed temporal data; and using the cryptographic key to enable access to a protected resource.
