On-Line Testing for Secure Implementations: Design and Validation

Abstract

On-line testing approaches can today be useful when designing circuits with severe security constraints. The reasons are summarized in the introduction to the special session on secure implementations (in these proceedings). The presentations in this special session aimed at introducing the specific concerns related to security as well as some approaches used to protect the circuits and to validate their robustness for certification. This panel aims at discussing in more details how on-line testing techniques can help in improving security and how the achieved level of security can be evaluated at different stages in the design flow. Various aspects are covered by the participants, including: counter-measures for fault attacks in hardware cryptographic primitives, design for test versus design for security, use of fault injection tools in evaluating the robustness against attacks and validation of security at the system level.
