Abstract (en)
[origin: CA3184856A1] The invention relates to a method in a first participating unit, preferably a first security element, having an electronic coin data set which is registered in a coin register of a payment system. The method has the steps of: generating a transaction data set relating to the transmission of the electronic coin data set to a second participating unit, preferably a second security element, or relating to a modification of the electronic coin data set, said modification to be registered on the coin register; encrypting the generated transaction data set using a cryptographic key, wherein the cryptographic key is composed of at least two cryptographic sub-keys, preferably at least three cryptographic sub-keys, of different respective remote entities; and initiating a communication connection to a transaction register of the payment system in order to transmit the encrypted transaction data set to the transaction register. The invention additionally relates to a participating unit, to a method in a transaction register, to a transaction register, and to a payment system.
