Patent attributes
Various embodiments relate to a method performed by a processor of a computing system. An example method includes receiving, by a computing system, an event. The event is associated with a digital signature in a first time-based message. The event signals a change to a property of the digital signature. The first time-based message includes a first trusted time stamp token from a timing authority. The first trusted time stamp token is generated using a first hash of digitally signed content, the digitally signed content generated by digitally signing content. The first time-based message is retrieved. A second hash of the first trusted time stamp token is generated. The second hash is transmitted to a timing authority. A second trusted time stamp token is received from the trusted timing authority in response to transmitting the second hash. A second time-based message is generated including the second trusted time stamp token.
