Vulnerability Analysis on Smart Cards Using Fault Tree

Abstract : In smart card domain, attacks and countermeasures are advancing at a fast rate. In order to have a generic view of all the attacks, we propose to use a Fault Tree Analysis. This method used in safety analysis helps to understand and implement all the desirable and undesirable events existing in this domain. We apply this method to Java Card vulnerability analysis. We define the properties that must be ensured: integrity and confidentiality of smart card data and code. By modeling the conditions, we discovered new attack paths to get access to the smart card contents. Then we introduce a new security api which is proposed to mitigate the undesirable events defined in the tree models.
