Abstract
Irrefutable public key digital signature time-stamps (1040) are created and used based upon, for example, the concept of transient time-interval-related secret cryptographic keys (2010), which are used to digitally sign (2030) submitted data during specific time intervals, and then permanently destroyed (2040). The public-key correlate for each time interval is saved for future authentication of the content of time-stamped data and time of creation of time-stamped data. The validity of the public keys is ensured through the certification of each time interval's public key using the previous time interval's secret key, immediately before that secret key is destroyed.
