This publication – at the side of the volumes LNAI 8589 and LNBI 8590 – constitutes the refereed complaints of the tenth overseas convention on clever Computing, ICIC 2014, held in Taiyuan, China, in August 2014. The ninety two papers of this quantity have been conscientiously reviewed and chosen from a variety of submissions.

A First Course in Coding Theory

The purpose of this booklet is to supply an simple remedy of the speculation of error-correcting codes, assuming not more than highschool arithmetic and the facility to hold out matrix mathematics. The e-book is meant to function a self-contained path for moment or 3rd 12 months arithmetic undergraduates, or as a readable advent to the mathematical facets of coding for college students in engineering or computing device technological know-how.

Learning Deep Architectures for AI

Can computing device studying carry AI? Theoretical effects, proposal from the mind and cognition, in addition to computing device studying experiments recommend that during order to profit the type of complex features which may characterize high-level abstractions (e. g. in imaginative and prescient, language, and different AI-level tasks), one would wish deep architectures.

Feistel Ciphers: Security Proofs and Cryptanalysis

This ebook offers a survey on other forms of Feistel ciphers, with their definitions and mathematical/computational houses. Feistel ciphers are accepted in cryptography with a purpose to receive pseudorandom variations and secret-key block ciphers. partially 1, we describe Feistel ciphers and their editions.

Example text

We refer to Proposition 1 for more details. Other related work. We have already briefly mentioned related work on key-alternating ciphers [7, 8, 14, 21, 38] as well as on XOR cascades [16, 18, 22], to which the beautiful work of Rogaway and Kilian on DESX (a special case of an XOR-cascade) should be added [19]. Coming back to cascade ciphers, Merkle and Hellman [31] show an attack on two-key triple encryption, which attack is revisited by Oorschot and Wiener [34]. ) Even and Goldreich [13] present a medley of observations on multiple encryption in various models, including some conclusions which are disputed by Maurer and Massey [27].

Xh+r is at most min{q, N } · ζ(q) r/2 2κ r/2 . Multiplying by 2r to account for all possible signatures concludes the proof. Proof of Lemma 2. Since Pr[A ∧ B] ≤ Pr[A|B] we have Pr [fitkey(τ, r, h) ≥ T ∧ fwd(τ ) ≤ ζ(q) ∧ bwd(τ ) ≤ ζ(q)] τ ∼Y ≤ Pr [fitkey(τ, r, h) ≥ T | fwd(τ ) ≤ ζ(q) ∧ bwd(τ ) ≤ ζ(q)] τ ∼Y where T ∈ {Czr , 1} is the bound we want to prove. When we condition on fwd(τ ) ≤ ζ(q) ∧ bwd(τ ) ≤ ζ(q), however, k ∗ is still independent uniformly at random (being entirely independent from QE in the ideal world), and so the expected number of r-chains that fit τ at position h is upper bounded by 2r · min{q, N } · ζ(q) r/2 2κ r/2 1 2κr (11) The Security of Multiple Encryption in the Ideal Cipher Model 35 by Proposition 1.
