The invention is an electronic writing device (50) and a method for creating an electronic signature, the device comprising a sensor (S1, S2, S2) for producing an output signal by detecting a dynamic parameter of a signature, and means for calculating a detected signature pattern on the basis of the output signal of the sensor (S1, S2, S2), comparing the detected signature pattern with a signature pattern stored in a memory and generating an enabling signal on the basis of the comparison, wherein the device also comprises a communication unit for implementing communication with a host system on the basis of the enabling signal. The device comprises a private key for the electronic signature and means for generating the electronic signature by means of the private key, wherein the communication unit is capable of receiving a data flow from the host system and supplying to the host system the electronic signature generated by means of the private key from the data flow.
