This ebook constitutes the refereed lawsuits of the twenty eighth Annual foreign convention at the idea and functions of Cryptographic ideas, EUROCRYPT 2009, held in Cologne, Germany, in April 2009.

The 33 revised complete papers awarded including 1 invited lecture have been conscientiously reviewed and chosen from 148 submissions. The papers handle all present foundational, theoretical and study features of cryptology, cryptography, and cryptanalysis in addition to complex purposes. The papers are prepared in topical sections on safeguard, proofs, and types, hash cryptanalysis, workforce and broadcast encryption, cryptosystems, cryptanalysis, aspect channels, curves, and randomness.

This publication comprises the result of the ninth IFIP WG five. five overseas summer time Workshop on Multimodal Interfaces, eNTERFACE 2013, held in Lisbon, Portugal, in July/August 2013. The nine papers integrated during this e-book characterize the result of a 4-week workshop, the place senior and junior researchers labored jointly on initiatives tackling new tendencies in human-machine interplay (HMI).

FoLLI-LNCS is the e-book platform for the organization of good judgment, Language and knowledge (FoLLI, www. folli. org). The organization was once based in 1991 to strengthen study and schooling at the interface among common sense, linguistics, desktop technology, and cognitive technological know-how. The FoLLI courses on common sense, Language and knowledge target to disseminate result of state of the art learn and instructional fabrics in those interdisciplinary components.

A commitment scheme Com = (S, R) is indistinguishable under selective openings (short IND-SO-COM secure) iff for every PPT n-message distribution M, and every PPT adversary A, we have that Advind-so Com,M,A is negligible. Here ind-so-real ind-so-ideal Advind-so Com,M,A (λ) := Pr ExpCom,M,A = 1 (λ) − Pr ExpCom,M,A = 1 (λ), ind-so-ideal where the experiments Expind-so-real Com,M,A and ExpCom,M,A are defined as follows: Experiment Expind-so-real Experiment Expind-so-ideal Com,M,A (λ) Com,M,A (λ) m = (m[i])i∈[n] ←$ M m = (m[i])i∈[n] ←$ M I ←$ A(recv), (Si (com, m[i]))i∈[n] I ←$ A(recv), (Si (com, m[i]))i∈[n] out A ←$ A(open), (Si (open))i∈I out A ←$ A(open), (Si (open))i∈I m ←$ M | m[I] return A(guess, m ) return A(guess, m) Again, we require from A that I ∈ Iλ , and we denote by A, (Si )i the output of A after interacting concurrently with instances Si of S.

Canetti [11]) in the sense that R (almost) takes the role of a UC-environment: R selects all inputs and reads the outputs (in particular the output of A). However, we stress that R may not actively interfere in the commitment protocol. Note that we cannot hope for fully UC-secure commitments for reasons not connected to the selective decommitment problem, cf. Canetti and Fischlin [12]. 22 M. Bellare, D. Hofheinz, and S. Yilek In all of the cases, we chose the weaker definitional variant for simplicity, which makes our negative results only stronger.

Bellare, D. Hofheinz, and S. 2 Black-box reductions. Reingold et al. [43] give an excellent overview and classification of black-box reductions. We recall some of their definitions which are important for our case. A primitive P = (FP , RP ) is a set FP of functions f : {0, 1}∗ → {0, 1}∗ along with a relation R over pairs (f, A), where f ∈ FP , and A is a machine. We say that f is an implementation of P iff f ∈ FP . Furthermore, f is an efficient implementation of P iff f ∈ FP and f can be computed by a PPT machine.
