Tamper Detection and Continuous Non-malleable Codes [PDF]

, 2015
WeN consider a public and keyless code (Enc,Dec) which is used to encode a message m and derive a codeword c = Enc(m). The codeword can be adversarially tampered via a function \(f \in{\mathcal F}\) from some “tampering function family” \(\mathcal F\), resulting in a tampered value c′ = f(c). We study the different types of security guarantees that can

Revisiting the Sanders-Freiman-Ruzsa Theorem in $\mathbb{F}_p^n$ and its Application to Non-malleable Codes

, 2016
Non-malleable codes (NMCs) protect sensitive data against degrees of corruption that prohibit error detection, ensuring instead that a corrupted codeword decodes correctly or to something that bears little relation to the original message.
