Alessandro Chiesa, Giacomo Fenzi ePrint Report The universal composability (UC) framework is a “gold standard” for security in cryptography. UC-secure protocols achieve strong security guarantees against powerful adaptive adversaries, and retain these guarantees when used as part of larger protocols. Zero knowledge succinct non-interactive arguments of knowledge (zkSNARKs) are a popular cryptographic primitive that are…

Nilanjan Datta, Shreya Dey, Avijit Dutta, Devdutto Kanungo ePrint Report In FSE’16, Luykx et al. have proposed $\textsf{LightMAC}$ that provably achieves a query length independent PRF security bound. To be precise, the construction achieves security roughly in the order of $O(q^2/2^n)$, when instantiated with two independently keyed $n$-bit block ciphers and $q$ is the total…

Joseph Jaeger ePrint Report We show that the adaptive compromise security definitions of Jaeger and Tyagi (Crypto ’20) cannot be applied in several natural use-cases. These include proving multi-user security from single-user security, the security of the cascade PRF, and the security of schemes sharing the same ideal primitive. We provide new variants of the…
