Unlinkable Policy-Based Sanitizable Signaturestantiation of . utilizing the Pointcheval-Sanders rerandomizable signature scheme and DTABS traceable attribute-based signature scheme, and analyze its efficiency. Finally, we compare . with P3S in terms of the features of the procedures, scalability, and security models.

Improved Graph-Based Model for?Recovering Superpoly on?Triviumested superpoly recovery framework proposed in ASIACRYPT 2021 and improve graph-based cube attack on Trivium by one round. The improved graph-based model performs better than monomial prediction with nested framework on 842- and 843-round cube attack of Trivium.

A Vulnerability in?Implementations of?SHA-3, SHAKE, EdDSA, and?Other NIST-Approved Algorithmsx, and macOS operating systems, and may also impact cryptographic algorithms that require SHA-3 or its variants, such as the Edwards-curve Digital Signature Algorithm (EdDSA) when the Edwards448 curve is used. We introduce the Init-Update-Final Test (IUFT) to detect this vulnerability in implementations.

Concrete Quantum Cryptanalysis of?Binary Elliptic Curves via?Addition ChainLT-based inversion. In particular, we analyze how several properties of addition chains, which do not affect the computational resources of classical FLT-based inversions, affect the computational resources of quantum FLT-based inversions and find appropriate sequences.

Classical and?Quantum Security of?Elliptic Curve VRF, via?Relative Indifferentiabilityr notion called ., and extend prior work to show that a standard domain extender used in ECVRF satisfies this notion, in both the classical and quantum settings. This final contribution is of independent interest and we believe it should be applicable elsewhere.

Sen (World Development 25(12), 1959–1961, 1997) contrasted human capital with what he termed as human capability, which is “the ability of human beings to lead lives they have reason to value and to enh
