The invention concerns a method for storing data in data storage means of a security module. The invention is characterised in that it consists in defining two storage zones (41, 42) whereof one (41) is designed to store data (a, b, c; d, e, f) by dispersed sections (a, b, c) (d, e, f) and the other (42) is designed to store addresses (AA, 92) where the data sections are located. The storage in the second storage zone is carried out in positions which are based on the address (83, 86) of the data sections in the first storage zone (41), as defined before dispersion. The invention also concerns a method for operating data units in a security module, and the associated security module.
