Revisiting the Wrong-Key-Randomization Hypothesis
Linear cryptanalysis can be considered to be one of the strongest techniques in the cryptanalyst’s arsenal. In most cases, Matsui’s Algorithm 2 is used for the key recovery part of the attack. The success rate analysis of this algorithm is based on an assumption regarding the bias of a linear approximation for a wrong key, known as the wrongkey-randomization hypothesis. This hypothesis was refi...
متن کاملFiltered Nonlinear Cryptanalysis of Reduced-Round Serpent, and the Wrong-Key Randomization Hypothesis
We present a deterministic algorithm to find nonlinear S-box approximations, and a new nonlinear cryptanalytic technique; the “filtered” nonlinear attack, which achieves the lowest data complexity of any known-plaintext attack on reduced-round Serpent so far. We demonstrate that the Wrong-Key Randomization Hypothesis is not entirely valid for attacks on reduced-round Serpent which rely on linea...
متن کاملRevisiting Address Space Randomization
Address space randomization is believed to be a strong defense against memory error exploits. Many code and data objects in a potentially vulnerable program and the system could be randomized, including those on the stack and heap, base address of code, order of functions, PLT, GOT, etc. Randomizing these code and data objects is believed to be effective in obfuscating the addresses in memory t...
متن کاملRevisiting the Dynamical Hypothesis
" There is a familiar trio of reactions by scientists to a purportedly radical hypothesis: (a) " You must be our of your mind! " , (b) " What else is new? Everybody knows that! " , and, later—if the hypothesis is still standing—(c) " Hmm. You might be on to something! " ((Dennett, 1995) p. 283)
متن کاملRevisiting the Stealth Trading Hypothesis
The stealth trading hypothesis (STH) states that informed traders concentrate their trades on medium sizes to conceal their information. Supporting empirical evidence for the NYSE case is considerable. In this paper, we question several methodological aspects of previous studies to provide new insights. We show that the STH cannot be rejected under alternative definitions of the trade-size cuto...
