MUTUAL ANTI-PIRACY AUTHENTICATION SYSTEM IN SMARTPHONE-TYPE SOFTWARE TOKENS AND IN THE SMS THEREOF

摘要

The invention relates to a system for mutual authentication of an operation between a first party (Party A) and a second party (Party B) on the basis of a dialogue during which said first and second parties exchange a predetermined number of one-time passwords. The system uses physical and logical hardware/software means to implement a procedure during which both parties exchange at least four one-time passwords (OTP) which are available to the second party (Party B) in a single third table (TB3), while for the first party (Party A) the passwords are distributed in two first tables (TA1, TA2) contained in different devices (DA1, DA2).
