We revisit the concept of *non-malleable* secret sharing (Goyal and Kumar, STOC 2018) in the computational setting. In particular, under the assumption of one-to-one one-way functions, we exhibit a *c...
In a poisoning attack against a learning algorithm, an adversary tampers with a fraction of the training data T with the goal of increasing the classification error of the constructed hypothesis/model...
In this paper, we introduce a new framework for constructing public-key encryption (PKE) schemes resilient to joint post-challenge/after-the-fact leakage and tampering attacks in the bounded leakage a...
Non-malleable codes were introduced by Dziembowski, Pietrzak, and Wichs (JACM 2018) as a generalization of standard error correcting codes to handle severe forms of tampering on codewords. This notion...
We construct efficient non-malleable codes (NMC) that are (computationally) secure against tampering by functions computable in any fixed polynomial time. Our construction is in the plain (no-CRS) mod...
We show a general framework for constructing non-malleable codes against tampering families with average-case hardness bounds. Our framework adapts ideas from the Naor-Yung double encryption paradigm ...
Austrin, Chung, Mahmoody, Pass and Seth (Crypto'14) studied the notion of bitwise pp-tampering attacks over randomized algorithms in which an efficient `virus' gets to control each bit of the randomne...
Non-malleable codes---introduced by Dziembowski, Pietrzak and Wichs at ICS 2010---are key-less coding schemes in which mauling attempts to an encoding of a given message, w.r.t.\ some class of tamperi...
Non-malleable codes were introduced by Dziembowski et al. (ICS 2010) as coding schemes that protect a message against tampering attacks. Roughly speaking, a code is non-malleable if decoding an advers...
A non-malleable code protects messages against a class of tampering functions. Informally, a code is non-malleable if the effect of applying any tampering function on an encoded message is to either...
Side channel and fault attacks take advantage from the fact that the behavior of crypto implementations can be observed and provides hints that simplify revealing keys. In a real word a lot of devic...
Given the increasing adoption of Bitcoin, the number of transactions and the block sizes within the system are only expected to increase. To sustain its correct operation in spite of its ever-increasi...
Non-malleable codes, defined by Dziembowski, Pietrzak and Wichs (ICS '10), provide roughly the following guarantee: if a codeword $c$ encoding some message $x$ is tampered to $c' = f(c)$ such that $c'...
Non-malleable coding, introduced by Dziembowski, Pietrzak and Wichs (ICS 2010), aims for protecting the integrity of information against tampering attacks in situations where error-detection is imposs...
We show how to leverage the RKA (Related-Key Attack) security of blockciphers to provide RKA security for a suite of high-level primitives. This motivates a more general theoretical question, namely, ...
