Instruction Duplication: Leaky and Not Too Fault-Tolerant!
Fault injection attacks alter the intended behavior of microcontrollers, compromising their security. These attacks can be mitigated using software countermeasures. A widely-used software-based solution to deflect fault attacks is instruction duplication and n-plication. We explore two main limitations with these approaches: first, we examine the effect of instruction duplication under fault at...
متن کاملPresuppositional Too, Postsuppositional Too
One of the insights of dynamic semantics in its various guises (Kamp 1981, Heim 1982, Groenendijk & Stokhof 1991, Kamp & Reyle 1993 among many others) is that interpretation is sensitive to left-to-right order. Is order sensitivity, particularly the default left-to-right order of evaluation, a property of particular meanings of certain lexical items (e.g., dynamically interpreted conjunction) o...
متن کاملToo much or too little
The global effort to understand the molecular drivers of cancer onset and progression is now coming to fruition with the identification of specific genomic and epigenomic events that influence signaling through key oncogenic pathways. Genetic studies using inducible expression of the critical growth controlling oncogenes MYC, RAS, PI3K and AKT have shown unequivocally that, in conjunction with ...
متن کاملNiger: too little, too late.

The policies...
متن کاملReducing Cardiovascular Risk: Too Little, Too Late, Too Short-Term
Vascular diseases in general, and cardiovascular disease in particular, are diseases of mass destruction, killing more people in the Western world (and increasingly in the developing world) than world wars. Each year, coronary heart disease kills over half a million Americans and over 100 000 British citizens each year, often prematurely (WHO online). A combination of migration, epidemiological...
