METHOD AND ARRANGEMENT FOR USER FRIENDLY DEVICE AUTHENTICATION
First Claim
1. A method of authenticating at least a first device to a user, the method comprising a conversion of a checksum generated within the first device to a user friendly output format, the method characterized by:
- a set up sequence, comprising a step ofreceiving and storing at least a first preferred output format selected from at least two user friendly output formats; and
a device configuration verification sequence comprising the steps of;
calculating the checksum;
converting the checksum to a user friendly output format, said conversion at least partly based on the selected preferred output format.

Abstract
The present invention relates to fraud prevention and authentication of a device to a user. The method of authenticating a personal device according to the invention comprises a set up sequence, wherein at least a first preferred output format is selected by the user, and a device configuration verification sequence. In the device configuration verification sequence a checksum is calculated and converted to a user friendly output format based on the user selected preferred output format. In addition the checksum may be calculated based on variable, and user selectable, keying material. The personal device, after being authenticated according to the above, may be used to authenticate a second device.
