In this paper we present two attacks that exploit cache events, which are visible in some side channel, to derive a secret key used in an implementation of AES. The first is an improvement of an adaptive chosen plaintext attack presented at ACISP 2006. The second is a new known plaintext attack that can recover a 128-bit key with approximately 30(More)
Malicious alterations of integrated circuits (ICs), introduced during either the design or fabrication process, are increasingly perceived as a serious concern by the global semiconductor industry. Such rogue alterations often take the form of a “hardware Trojan,” which may be activated from remote after the compromised chip or system has been deployed in(More)
