In 2010, Sood et al [3] proposed a secure dynamic identity based authentication scheme using smart cards. They claimed that their scheme is secure against various attacks. In this paper, we improve their scheme for outsider attack as well as insider attack. To remedy these security flaws, an improved scheme is proposed to withstand these attacks. [1] Introduction With the rapid increasing need ...

We revisit the classical algorithms for searching over sorted sets and introduce an algorithm refinement, called adaptive search, that combines the good features of Interpolation search and those of Binary search. W.r.t. Insertion sort, only a constant number of extra comparisons is introduced. Yet, under several relevant input data distributions our algorithm shows average case cost comparable...

Yi et al. have proposed a cipher called the fast encryption algorithm for multimedia (FEA-M). Recently Mihaljević and Kohno pointed out that FEA-M is insecure. However, their attacks are not efficient: their chosen plaintext attack and known plaintext attack require 2-bit chosen plaintext and 2-bit known plaintext, respectively. In this paper we give an efficient known plaintext attack against ...

Bruce C. Berndt et al. and Soon-Yi Kang have proved many of Ramanujan’s formulas for the explicit evaluation of the Rogers-Ramanujan continued fraction and theta-functions in terms of Weber-Ramanujan class invariants. In this note, we give alternative proofs of some of these identities of theta-functions recorded by Ramanujan in his notebooks and deduce some formulas for the explicit evaluation...

The concept of prefactors is considered in order to decrease the complexity of the Guruswami–Sudan interpolation step for generalized Reed–Solomon codes. It is shown that the well-known re-encoding projection due to Kötter et al. [1] leads to one type of such prefactors. The new type of Sierpinski prefactors is introduced. The latter are based on the fact that many binomial coefficients in the ...

Theoretical computation of the pressure dependence superconducting state parameters of binary Ca60Al40 is reported using model potential formalism. Explicit expressions have been derived for the volume dependence of the electron–phonon coupling strength λ and the Coulomb pseudopotential μ* considering the variation of Fermi momentum KF and Debye temperature ӨD with volume. Well known Ashcroft’s...

1 We define b-compatibility for planar curves and propose three 2 ball morphing techniques (b-morphs) between pairs of b3 compatible curves. B-morphs use the automatic ball-map 4 correspondence, proposed by Chazel et al. [11], from which 5 they derive vertex trajectories (Linear, Circular, Parabolic). 6 All are symmetric, meeting both curves with the same an7 gle, which is a right angle for the...
