摘要
Method for generating a challenge word, electronic device, input peripheral, and system implementing said method. The invention relates to a system and to a method for generating a challenge word (WCH) that is intended to be used in the context of an authentication request (Mi). Such a system particularly relies on an electronic device (10) and an input peripheral (20) that are in communication (NI) with each other. The challenge word (WCH) is produced by said system on the basis of a candidate word (WCD) generated by said electronic device (10) and a piece of input information (IC) generated by said input peripheral (20). The invention offers a robust alternative to the major attacks experienced when entering a secret challenge word on a physical or virtual keyboard.
