KLEIN is a family of lightweight block ciphers presented at RFIDSec 2011 that combines a 4-bit Sbox with Rijndael’s byte-oriented MixColumn. This approach allows compact implementations of KLEIN in both low-end software and hardware. This paper shows that interactions between those two components lead to the existence of differentials of unexpectedly high probability: using an iterative collect...

Abstract. A homogeneous space G/H is said to have a compact Clifford-Klein form if there exists a discrete subgroup Γ of G that acts properly on G/H such that the quotient space Γ\G/H is compact. When n is even, we find every closed connected subgroup H of G = SO(2, n), such that G/H has a compact Clifford-Klein form, but our classification is not quite complete when n is odd. The work reveals ...

A homogeneous space G/H is said to have a compact Clifford-Klein form if there exists a discrete subgroup Γ of G that acts properly discontinuously on G/H, such that the quotient space Γ\G/H is compact. When n is even, we find every closed, connected subgroup H of G = SO(2, n), such that G/H has a compact Clifford-Klein form, but our classification is not quite complete when n is odd. The work ...

In this paper,Kaluza-Klein space-time with quark and strange matter in gravity has been considered. The general solutions of the field equations Kaluza-Klein have obtained under assumption constant deceleration parameter. physical geometrical aspects model are also discussed details.
