The notion of non-malleable cryptography, an extension of semantically secure cryptography, is defined. Figures and Topics from this paper. figure 1.


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. To the best of our knowledge we present the first generic compiler for leakage-resilient secret …

Informally, a code is non-malleable if the message contained in a modified code-word is either the original message, or a completely unrelated value. including the original one proposed in [GM84], are easily malleable. Thus, non-malleability is a strictly stronger requirement than semantic security. Moreover, non-malleability is often times indispensable in practical applications. For exam-ple, no one would consider secure an electronic “sealed-bid” auction in which an A metal that you can hammer into thin sheets is malleable. Gold, silver, aluminum, iron, and copper are malleable. Non-malleable metals such as tin will break apart when struck by a hammer.

In order to get a better view of malleable and non-malleable codes, we refer to El-Gamal [ElG85] and Cramer-Shoup [CS98]cryptosystems. We recall the structure of these two cryptosystems by the following: El-Gamal cryptosystem [ElG85]. This cryptosystem consists of the two following phases: 1.Encryption phase: oT encrypt message m(encoded as a group el-

Title: Improved Non-Malleable Extractors, Non-Malleable Codes and Independent Source Extractors Multi-source non-malleable extractors are special independent source extractors which satisfy an additional non-malleability property. This property requires that the output of the extractor remains close to uniform even conditioned on its output generated by tampering {\it several sources together}. 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.

Non-Malleable Zero Knowledge: Black-Box Constructions and De nitional Relationships Abhishek Jain Omkant Pandeyy Abstract This paper deals with e cient non-malleable zero-knowledge proofs for NP, based on general assumptions. We construct a simulation-sound zero-knowledge (ZK) protocol for NP, based only on the black-box use of one-way functions.

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.
