ePrint ReportIn this article, a prototype which enables such security management is described. The solution is based on a double-processor architecture: one processor embeds a representative set of countermeasures (and mechanisms to define their parameters) and executes the application code. The second processor, on the same chip, applies a given security strategy, but without requesting sensitive data from the first processor. The chosen strategy is based on fuzzy logic reasoning to enable the designer to describe, using a fairly simple formalism, both the attack paths and the normal use cases. A proof of concept has been proposed for the smart card part of a conditional access for Pay-TV, but it could easily be fine-tuned for other applications.
