CARTE A CIRCUIT INTEGRE COMPRENANT DES MOYENS DE PROTECTION DU CIRCUIT INTEGRE.

摘要

A system for protecting integrated circuits on smart cards is described. The circuit (103) is placed in a cavity (102) in a ceramic housing (101). Standard contacts (104) are deposited on the side of the housing opposite to the cavity opening and connected to the chip (103) via feed-through conductors (106) extending into the cavity (102) and connected therein to wires (105) which are welded to the chip (103). The cavity (102) is either sealed by a cover (108) or filled with a protective material (208). Smart cards with a lifetime of over ten years may thus be obtained.
