Side channel cryptanalysis techniques, such as the analysis of instantaneous power consumption, have been extremely eeective i n attacking implementations on simple hardware platforms. There are several proposed solutions to resist these attacks, most of which are addhoc and can easily be rendered ineeective. A scientiic approach is to create a model for(More)
We present template attacks, the strongest form of side channel attack possible in an information theoretic sense. These attacks can break implementations and countermeasures whose security is dependent on the assumption that an adversary cannot obtain more than one or a limited number of side channel samples. They require that an adversary has access to an(More)
NIST has considered the performance of AES candidates on smart-cards as an important selection criterion and many submitters have highlighted the compactness and eeciency of their submission on low end smart cards. However, in light of recently discovered power based attacks, we strongly argue that evaluating smart-card suitability of AES candidates(More)
Detecting attacks against systems has, in practice, largely been delegated to sensors, such as network intrustion detection systems. However, due to the inherent limitations of these systems and the increasing use of encryption in communication, intrusion detection and prevention have once again moved back to the host systems themselves. In this paper, we(More)
M–commerce is a new area arising from the marriage of electronic commerce with emerging mobile and pervasive computing technology. The newness of this area—and the rapidness with which it is emerging—makes it difficult to analyze the technological problems that m–commerce introduces—and, in particular, the security and privacy issues. This situation is not(More)
IgG4-related disease is a newly recognized fibro-inflammatory condition characterized by several features: a tendency to form tumefactive lesions in multiple sites; a characteristic histopathological appearance; and-often but not always-elevated serum IgG4 concentrations. An international symposium on IgG4-related disease was held in Boston, MA, on 4-7(More)
Non-inflammatory cystic lesions of the pancreas are increasingly recognized. Two distinct entities have been defined, i.e., intraductal papillary mucinous neoplasm (IPMN) and mucinous cystic neoplasm (MCN). Ovarian-type stroma has been proposed as a requisite to distinguish MCN from IPMN. Some other distinct features to characterize IPMN and MCN have been(More)
Mashup applications mix and merge content (data and code) from multiple content providers in a user's browser, to provide high-value web applications that can rival the user experience provided by desktop applications. Current browser security models were not designed to support such applications and they are therefore implemented with insecure workarounds.(More)

The international consensus guidelines for management of intraductal papillary mucinous neoplasm and mucinous cystic neoplasm of the pancreas established in 2006 have increased awareness and improved the management of these entities. During the subsequent 5 years, a considerable amount of information has been added to the literature. Based on a consensus(More)
