ABSTRACT:
Method for securing a session over a radio or infrared wireless link (101) between a terminal (11) and a mobile equipment (10), said session being secured with a SIM card (100) in said mobile equipment (10). The terminal (11) and the mobile equipment (10) both comprise a display and a keyboard or keypad and can be mutually connected through said short distance wireless link (101). The method comprises the following steps:generating a secret in one of said terminals or said smart cards,displaying this secret on the display of said terminal (11) or said user equipment (10),entering said secret or the hash value of said secret on the input means of the other one of said terminals (11) or user equipments (10),using said shared secret for securing at least a part of said session over said short distance wireless link (101).
