'''Transient-key cryptography''' is a form of [[public-key cryptography]] wherein [[keypair]]s are generated and assigned to brief [[Interval (time)|intervals]] of time instead of to individuals or organizations, and the blocks of cryptographic data are chained through time. In a transient-key system, [[private key]]s are used briefly and then destroyed, which is why it is sometimes nicknamed “disposable crypto.” Data encrypted with a private key associated with a specific time interval can be irrefutably linked to that interval, making transient-key [[cryptography]] particularly useful for [[Trusted timestamping|digital trusted timestamping]]. Transient-key cryptography was invented in 1997 by [[Dr. Michael Doyle]] of [[Eolas]], and has been adopted in the [[ANSI ASC X9.95 Standard]] for [[Trusted timestamping|trusted timestamps]].
