The method involves configuring a cryptographic processing system i.e. terminal by obtaining and memorizing a reference value (Co) in the terminal (E0). A memorized test (ChallR) is transmitted (E10) to a user, and a response (R') is obtained (E20) from the user. A cryptographic processing of the reference value and a cryptographic function is performed (E30) based on a sensitive data item e.g. password, where the reference value and the test are in the memory of the terminal, and a solution is not in the memory of the terminal during the transmission of the test. Independent claims are also included for the following: (1) a computer program for cryptographic processing (2) a processor readable medium storing a program for cryptographic processing (3) a cryptographic processing system. |
