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 ...
Non-Malleable Codes from Average-Case Hardness: AC0, Decision Trees, and Streaming Space-Bounded Tampering
non-malleable codes streaming
2017/11/3
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 ...
Non-Malleable Codes for Space-Bounded Tampering
Non-malleable Codes Proofs of Space Tamper-resilient Cryptography
2017/6/8
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...
Key-Evolution Schemes Resilient to Space-Bounded Leakage
secret-key cryptography / graph pebbling, leakage-resilient cryptography, bounded-retrieval model
2012/3/26
Much recent work in cryptography attempts to build secure schemes in the presence of \emph{side-channel leakage} or leakage caused by malicious software, like computer viruses. In this setting, the ad...
