Embodiment Construction

[0025] The exemplary embodiments of the invention presented in this patent application are to be construed so as to limit the applicability of the appended claims. In this patent application the verb "to comprise" is used as an open limitation which does not exclude the existence of likewise unrecited features. The features recited in dependent claims are mutually freely combinable unless otherwise explicitly stated.

[0026] figure 2 Message 201 is schematically illustrated, which we may designate as a multimedia message for the sake of generality. Important message features for the present invention are that it is electronically transferable from the network to individual user terminals and that it has a well-defined and standardized structure that makes it acceptable to a large number of mobile terminal users and useful. A further feature of the message 201 which is also important to the invention is that its standardized composition defines a network-generated part 202...

Abstract

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.

Description

technical field [0001] The present invention generally relates to techniques for electronically transmitting relatively short and compact messages representing securities. In particular, the invention relates to how to ensure that such a message, when presented for inspection, is an authenticated one and not an illegal copy. Background technique [0002] Electronic transmission of various bills, discount coupons and corresponding securities (a commodity of value) in the form of SMS messages (Short Message Service), MMS messages (Multimedia Message Service) and similar compact, well-defined messaging formats is rapidly becoming popular. As an example, we may consider the known method of ordering and transferring public transport tickets, such as train or bus tickets, to the mobile phone of an individual user. figure 1 In , we assume that the user of the mobile phone 101 wants to order an electronically delivered bus ticket. The mobile phone 101 has a wireless communication...
