Modified Original Smart Cards and Smart Card Clone Countermeasures

Abstract

Conditional Access Systems are used in Pay-Tv Sys- tems to ensure conditional access to broadcasted data and charge subscribers a subscription fee. Smart cards are end- user security devices to store subscribers entitlements, re- quired to access data. On the other hand, pirates clone or modify smart cards to gain access to broadcasted data with- out paying any fees. This paper presents new countermea- sures, based on fingerprints, to avoid smart cards cloning or modifying in Conditional Access Systems for digital Tv broadcasting.
