The present invention relates to a method, a system and a computer-readable medium storing computer-executable components in connection with transfer of information data to a recipient. The invention is based on the idea that generation of random number data and the calculation of digital signatures are performed before information data is accessible to a digital pen. Since asymmetric encryption of data is a demanding operation for said digital pen to perform in terms of processing power, a lot of time can be saved if the generation of random number data and asymmetric encryption of said random number data is performed in advance, when the pen is in an idle, non-communicating mode, for example during battery loading of the pen or when the pen is lifted from the position-coded paper. This alleviates delay times when the pen is in its communicating mode.
