Abstract
The technology disclosed herein provides an enhanced access control mechanism that uses a proof-of-work key wrapping system to temporally restrict access to data. An example method may include: determining, by a processing device, characteristics of a computing device; accessing a cryptographic key for accessing content; selecting a set of cryptographic attributes for wrapping the cryptographic key, wherein the set of cryptographic attributes are selected to enable the computing device to derive the cryptographic key from a wrapped key in a predetermined duration of time; and providing the wrapped key and an indication of at least one of the cryptographic attributes to the computing device.
