Abstract (en)
[origin: WO2022233454A1] The invention relates to a method (400) for registering (104) an electronic coin data set (C) in a coin register (2) of an electronic payment system (BZ), said method comprising the steps of: generating (405) an electronic coin data set (Cj), which has a monetary value (vj) and an obfuscation value (rj), by means of a first subscriber unit (TE1) of the payment system (BZ), said monetary value (vj) of the generated electronic coin data set (Cj) corresponding to the monetary value (m) of an electronic coin data set (Ci) present in the first subscriber unit (TE1); masking (406) the generated electronic coin data set (Cj) by means of the first subscriber unit (TE1) by applying a one-way function (f(C)) to at least one data element of the electronic coin data set (Cj) in order to obtain a masked generated electronic coin data set (Zj); transmitting a registration request (407) for the masked generated electronic coin data set (Zj) together with a timelock from the first subscriber unit (TE1) to the coin register (2), wherein the timelock specifies a period of time (T2) until the generated electronic coin data set (Cj) can be switched over to a second subscriber unit (TE2) of the payment system (BZ) in the coin register (2). The invention additionally relates to a coin register (2), a payment system (BZ), a subscriber unit (TE), and a computer program product.
