Enhanced Doubling Attacks on Signed-All-Bits Set Recoding
In cryptographic devices like a smart card whose computing ability and memory are limited, cryptographic algorithms should be performed efficiently. However, the issue of efficiency sometimes raises vulnerabilities against side channel attacks (SCAs). In elliptic curve cryptosystems, one of main operations is the scalar multiplication. Thus it must be constructed in safety against SCAs. Recentl...
متن کاملString bits and the Myers effect
Based on the non-abelian effective action for D1-branes, a new action for matrix string theory in non-trivial backgrounds is proposed. Once the background fields are included, new interactions bring the possibility of non-commutative solutions i.e. The Myers effect for “string bits” .
متن کاملA lattice fermion without doubling
A free fermion without doubler is formulated on 1+D dimensional discrete Minkowski space-time. The action is not hermitian but causes no harm. In 1+3 dimensional massless case the equation describes a single species of Dirac particle in the continuous space-time limit. In 1+1 dimensional massless case the equation is the same as the automaton equation by ’t Hooft and describes a chiral fermion....
متن کاملCalculating the rest tension for a polymer of string bits.
We explore the application of approximation schemes from many body physics, including the Hartree-Fock method and random phase approximation (RPA), to the problem of analyzing the low energy excitations of a polymer chain made up of bosonic string bits. We accordingly obtain an expression for the rest tension T0 of the bosonic relativistic string in terms of the parameters characterizing the mi...
متن کاملString without strings
Scale invariance provides a principled reason for the physical importance of Hilbert space, the Virasoro algebra, the string mode expansion, canonical commutators and Schroedinger evolution of states, independent of the assumptions of string theory and quantum theory. The usual properties of dimensionful fields imply an infinite, projective tower of conformal weights associated with the tangent...
