Leakage resilient secret sharing (LRSS) allows a dealer to share a secret amongst n parties
such that any authorized subset of the parties can recover the secret from their shares, while …

Secret sharing enables a dealer to split a secret into a set of shares, in such a way that
certain authorized subsets of share holders can reconstruct the secret, whereas all …

We introduce a natural generalization of two-source non-malleable extractors (Cheragachi
and Guruswami, TCC 2014) called as multi-source non-malleable extractors. Multi-source …

Various notions of non-malleable secret sharing schemes have been considered. In this
paper, we review the existing work on non-malleable secret sharing and suggest a novel …

Leakage-resilient secret sharing has mostly been studied in the compartmentalized models,
where a leakage oracle can arbitrarily leak bounded number of bits from all shares, provided …

Implementation attacks such as power analysis and fault attacks have shown that, if potential
attackers have physical access to a cryptographic device, achieving practical security …

We study leakage-resilient continuously non-malleable secret sharing, as recently
introduced by Faonio and Venturi (CRYPTO 2019). In this setting, an attacker can …

We study non-malleable secret sharing against joint leakage and joint tampering attacks.
Our main result is the first threshold secret sharing scheme in the plain model achieving …

Abstract Evolving secret sharing (Komargodski, Naor, and Yogev, TCC'16) generalizes the
notion of secret sharing to the setting of evolving access structures, in which the share …

Leakage-resilient cryptography aims to protect cryptographic primitives from so-called “side
channel attacks” that exploit their physical implementation to learn their input or secret state …
