SYSTEM UND VERFAHREN FÜR DAS ERNEUERN VON SCHLÜSSELN, WELCHE IN PUBLIC-KEY KRYPTOGRAPHIE GENUTZT WERDEN

An embodiment of the invention includes a provider system (100) for providing a sequence of public keys to a receiver system (200), wherein each public key of the sequence is related to a private key and is applicable for a public key cryptography procedure. The provider system (100) comprises a computing unit (110) and a sending unit (120). The computing unit (110) is configured to: generate the sequence of public keys and related keys and compute a plurality of data sets, a data set of the plurality comprising a public key and a proof value. The proof values is a result of applying a hash function to a following data set comprising a further public key following in the sequence. The sending unit (120) is configured to provide the plurality of data to a receiver system (200).
