Cryptanalysis of PKP: A New Approach
Quite recently, in [4], a new time-memory tradeoff algorithm was presented. The original goal of this algorithm was to count the number of points on an elliptic curve, however, the authors claimed that their approach could be applied to other problems. In this paper, we describe such an application and show a new way to attack the Permuted Kernel Problem. This new method is faster than any prev...
متن کاملConstraints on D′′ structure using PKP(AB–DF), PKP(BC–DF) and PcP–P traveltime data from broad-band records
S U M M A R Y The effects of complex structure in the deep mantle and D′′ on PKP differential traveltimes should be estimated accurately in order to reach reliable conclusions concerning the physical and chemical properties of the Earth’s inner and outer core. In particular, it is important to assess how much of the data can be explained by mantle structure alone. For this purpose, we have asse...
متن کاملTime dependence of PKP(BC)–PKP(DF) times: could this be an artifact of systematic earthquake mislocations?
Differential inner core rotation was first detected from time-dependent observations of differential travel times between PKP(DF) waves (which go through the inner core) and PKP(BC) waves (which turn at the bottom of the outer core) (Song and Richards, 1996). Criticisms concerning the reported detection have been raised, the most significant one being the possible bias from potential systematic...
متن کاملAnalysis of Some Natural Variants of the PKP Algorithm
In 1989, (Shamir, 1989) proposed a new zero-knowledge identification scheme based on a NP-complete problem called PKP for Permuted Kernel Problem. For a given prime p, a given matrix A and a given vector V , the problem is to find a permutation π such that the permuted vector Vπ verifies A ·Vπ = 0 mod p. This scheme is still in 2011 known as one of the most efficient identification scheme based...
متن کاملMolekularna charakterystyka guzów leiomyoma uteri na przykładzie wybranych składników macierzy pozakomórkowej* Molecular characteristics of leiomyoma uteri based on selected compounds of the extracellular matrix
Mięśniak gładkokomórkowy macicy (Leiomyoma uteri) jest niezłośliwym nowotworem monoklonalnym złożonym z komórek mięśni gładkich i zrębu zbudowanego z włóknistej tkanki łącznej. Najczęściej jest umiejscowiony w błonie mięśniowej macicy u kobiet w wieku rozrodczym. Czynnikami mogącymi przyspieszać jego wzrost są ciąża i terapia hormonalna. Jest to także guz pośrednio zależny od stężenia hormonów ...
