FUNDAMENTALS, VOL.E94–A, NO.1 JANUARY 2011 The binding property requires even adversarial senders S∗ cannot decommit the same commitment c to two diﬀerent v In this paper, ultraflexible and malleable iron (Fe)/BaTiO 3 (BTO) multiferroic heterostructures are demonstrated, showing a perfect crystallinity and hetero‐epitaxial growth. In terms of performance, they indicate good multiferroic properties and excellent bending tunability, as well as obvious magnetoelectric (ME) coupling effect. Malleable cast iron fittings are designed according to the EN 10242 standard and available in black and hot-dip galvanized versions. They are threaded according to EN 10226-1. The material ensures resistance against mechanical stress and long The Paper Kites - Malleable Beings from "States" (2013) The Paper Kites - Malleable Beings from "States" (2013) Skip navigation Sign in.

These constructions have already found a number of applications in cryptography. We investigate the natural question of constructing t-out-of-n non-malleable secret sharing schemes.

Non-malleable codes (NMC) introduced by Dziembowski et al. [ICS’10] allow one to encode “passive” data in such a manner that when a codeword is tampered, the original data either remains completely intact or is essentially destroyed.In this work, we initiate the study of interactive non-malleable codes (INMCs) that allow for encoding This paper introduces an extension of the standard non-malleability security notion - so-called continuous non-malleability - where we allow the adversary to tamper continuously with an encoding. This is in contrast to the standard notion of non-malleable codes where the adversary only is allowed to tamper a single time with an encoding. The notion of non-malleable cryptography, an extension of semantically secure cryptography, is defined. Informally, the additional requirement is that given the ciphertext it is impossible to generate a different ciphertext so that the respective plaintexts are related.

There is an explicit and efﬁcient non-malleable code that is unconditionally secure against AC0 circuits with codeword length n = k1+o(1) for a k-bit message and negligible error. Prior to our work, there were no known constructions of polynomial-rate non-malleable codes even for depth- Concurrent Non-Malleable Zero Knowledge Proofs 433 2.1 Concurrent Non-Malleable Zero-Knowledge We recall the deﬁnition of concurrent non-malleable zero-knowledge from [BPS06], which in turn closely follows the deﬁnition of simulation extractabil-ity of [PR05]. Let P,V be an interactive proof for a languageL ∈NPwith witness relation R In this paper we modify the construction to solve the above barrier. Using the currently best explicit non-malleable extractors we get an explicit bipartite Ramsey graphs for sets of size 2k, fork = O(lognloglogn). Any further improvement in the construction of non-malleable extractors would immediately yield a corresponding two-source extractor.

Throughout this paper, let x Xdenote that the random variable xsampled uniformly from a set X. Let ?denote a special symbol. 2.1 Non-malleable codes A coding scheme is a pair of functions (enc;dec), where enc : M!Xis a randomized encoding " Non metals are not malleable ". Malleability is seen when any element doesn't break on hitting and then it gets formed like thin sheets. Suppose you hit coal, then upto some extent it will bear and then it will break into pieces. And this nature of breaking down defies the malleability property of nonmetals. 2005-07-11 Seeded non-malleable extractors were introduced by Dodis and Wichs in [DW09], as a generalization of strong seeded extractors. Deﬁnition 1.2 (Non-malleable extractor).

We also show that 1 - α is the best achievable rate for the family of functions, which are only allowed to tamper the first αn bits of the codeword, which is of special interest. stances of itself, such schemes cannot be proved non-malleable. The paper shows an eﬃcient commitment scheme proven to be non-malleable even in the multiple-instances setting, based on the KEA1 and DDH assumptions. Our scheme has a simulator that works in a straight-line manner by using the KEA1-extractor instead of the rewinding strategy. A non-malleable secret sharing scheme guarantees that a secret that is reconstructed from a set of tampered shares is either equal to the original secret or completely unrelated.
