Quantum Leakage Resilience of Shamir Secret Sharing

We initiate the study of quantum leakage resilience of unmodified Shamir secret sharing over prime fields. A well-studied leakage model for Shamir's secret sharing classically is single-bit local leakage from each share. We consider its quantum analogue where, for each party, a local leakage...

Sharks has a Bias of Polynomial Coefficients in Secret Sharing

Affected versions of this crate allowed for a bias when generating random polynomials for Shamir Secret Sharing, where instead of being within the range 0, 255 they were instead in the range 1, 255. A description from Cure53, who originally found the issue, is available: The correct method to...

WS-2020-0444

All versions of shamir rust crate before 2.0.0 did not properly calculate secret shares requirements. This reduces the security of the shamir secret sharing algorithm by restricting the crate to always using a threshold value of three, rather than a configurable limit...

CVE-2023-25000 Vault Vulnerable to Cache-Timing Attacks During Seal and Unseal Operations

HashiCorp Vault's implementation of Shamir's secret sharing used precomputed table lookups, and was vulnerable to cache-timing attacks. An attacker with access to, and the ability to observe a large number of unseal operations on the host through a side channel may reduce the search space of a...
