<p>An authentication arrangement (101), such as a smart card, is identified by an authentication arrangement identification number and communicates with a communication system (102) comprising a transaction manager (110, 111) and an authentication manager (110, 111). The authentication arrangement comprises means for receiving personalizing information from the authentication manager (110, 111) associating the authentication arrangement (101) with the transaction manager (110, 111). Further, the arrangement comprises means for calculating, for a transaction that requires authentication of the user between the user and the transaction manager (110, 111), a substantially non-recurring identification code (100), which depends on the personalizing information. Also comprised in the authentication arrangement are means for supplying the identification code (100) to the user. The user is thereby enabled to authenticate with the transaction manager (110, 111).</p> |
