Improved Polynomial Secret-Sharing Schemes
Despite active research on secret-sharing schemes for arbitrary access structures for more than 35 years, we do not understand their share size – the...

Yoyo attack on 4-round Lai-Massey scheme with secret round functions
In this study, we present the first yoyo attack to recover the secret round function of the 4-round Lai-Massey scheme with an affine orthomorphism....

ZK-PCPs from Leakage-Resilient Secret Sharing
Zero-Knowledge PCPs (ZK-PCPs; Kilian, Petrank, and Tardos, STOC ‘97) are PCPs with the additional zero-knowledge guarantee that the view of any...

Obfustopia Built on Secret-Key Functional Encryption
We show that indistinguishability obfuscation (IO) for all circuits can be constructed solely from secret-key functional encryption (SKFE). In the...

On Abelian and Homomorphic Secret Sharing Schemes
Homomorphic (resp. abelian) secret sharing is a generalization of ubiquitous linear secret sharing in which the secret value and the shares are taken...

Why secret detection tools are not enough: It’s not just about false positives - An industrial case study
Checked-in secrets in version-controlled software projects pose security risks to software and services. Secret detection tools can identify the...
