Abstract
In a method and arrangement for authenticated transmission of a personalized data set or program to a hardware security module in a device such as a franking machine, a system manufacturer buys security modules, from a security module manufacturer and incorporate the security modules at a production site in the device and loads a data set and/or an application program into the security module, making the device operable. Authentication occurs using a first security module-specific fixed code, a second security module-specific fixed code that is calculated from the first code according to a given algorithm, and a third security module-specific fixed code that is calculated from the second code and the data in the data set and/or in the program.
