Which Security Policy for Multiapplication Smart Cards?
Pierre Girard, Cryptography and Security R&D, GEMPLUS
Abstract
In this paper, we aim to clarify some issues regarding the deployment
context of multiapplicative smart cards. We especially deal with the
trust relationships between the involved parties and the resulting
constraints from a security point of view.
We highlight a new security threat in a multiapplicative context and
propose a new multilevel security model which allows to control
precisely the information flows inside the card, and to detect illegal
data sharing.
Finally we illustrate all the proposed concepts on an multiapplicative
example involving three applications.
