Continuous Space-Bounded Non-Malleable Codes from Stronger Proofs-of-Space
Non-Malleable Codes Proofs of Space Tamper-resilience
2019/5/24
Non-malleable codes are encoding schemes that provide protections against various classes of tampering attacks. Recently Faust et al. (CRYPTO 2017) initiated the study of space- bounded non-malleable ...
Inception makes non-malleable codes shorter as well!
Non-malleable codes Randomness extraction
2019/4/22
Non-malleable codes, introduced by Dziembowski, Pietrzak and Wichs in ICS 2010, have emerged in the last few years as a fundamental object at the intersection of cryptography and coding theory. Non-ma...

2019/4/16
We construct efficient, unconditional non-malleable codes that are secure against tampering functions computed by decision trees of depth d=n1/4−o(1)d=n1/4−o(1). In particular, each bit of...

2019/1/26
For the case of split-state tampering, we establish the existence of rate-one continuously non-malleable codes with computational security, in the (non-programmable) random oracle model. We further ex...

2018/11/2
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...

2018/6/19
Non-malleable codes for the split-state model allow to encode a message into two parts, such that arbitrary independent tampering on each part, and subsequent decoding of the corresponding modified co...

2018/6/5
At ICS 2010, Dziembowski, Pietrzak and Wichs introduced the notion of *non-malleable codes*, a weaker form of error-correcting codes guaranteeing that the decoding of a tampered codeword either corres...

Recently, Faust et al. (TCC'14) introduced the notion of continuous non-malleable codes (CNMC), which provides stronger security guarantees than standard non-malleable codes, by allowing an adversary ...
