Abstract (en)
[origin: WO2004015917A1] A method and an arrangement are disclosed for authenticat-ing a commodity of value delivered from a closed network as a digital message (201) to a mobile terminal. The digital message (201) has a predefined format that comprises fields (204, 205) for network-generated values (206, 208). Authenticating involves generating (311, 406) a code value according to a time-dependent rule, so that the generated code value depends on the moment of time when the digital message will be transmitted. The generated code value is inserted (311, 406) into a certain first field (204) in the digital message, which first field has a predefined role that is other than conveying code values. Another value that represents message transmission time is inserted (407) into a second field (205) in the digital message.
