Abstract
On crée et on utilise des horodateurs (1040) numériques à clés publiques irréfutables en se basant, par exemple, sur le concept de clés cryptographiques secrètes transitoires associées à l'intervalle de temps, qui sont utilisées pour la signature numérique (2030) des données soumises au cours d'intervalles de temps spécifiques, puis détruites (2040) définitivement. Le corrélat de clé publique pour chaque intervalle de temps est mémorisé en vue d'une authentification future du contenu des données horodatées et du moment de création des données horodatées. La validité des clés publiques est assurée par la certification de chaque clé publique d'intervalle de temps au moyen de la clé secrète de l'intervalle de temps précédente, immédiatement avant que cette clé secrète soit détruite.
