My Traces Learn What You Did in the Dark: Recovering Secret Signals Without Key Guesses
In side channel attack (SCA) studies, it is widely believed that unprotected implementations leak information about the intermediate states of the internal cryptographic process. However, directly recovering the intermediate states is not common practice in today’s SCA study. Instead, most SCAs exploit the leakages in a “guess-anddetermine” way, where they take a partial key guess, compute the ...
متن کاملMobReduce: Reducing State Complexity of Mobility Traces
User traces are essential for analysis of human behavior and development of opportunistic networking protocols and applications. As user traces are collected with high granularity to apply them in diverse scenarios, they have a high complexity resulting from the large number of user states. We present MobReduce: a methodology for reducing the number of states in user traces. We apply MobReduce ...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
15 صفحه اولAn Efficient State Recovery Attack on X-FCSR-256
We describe a state recovery attack on the X-FCSR-256 stream cipher of total complexity at most 2. This complexity is achievable by requiring 2 output blocks with an amortized calculation e ort of at most 2 table lookups per output block using no more than 2 table entries of precomputational storage.
