Abstract
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.
