Card-based cryptography is an area involving cryptographic techniques that use a deck of physical cards to implement secure computation. In this paper, we study card-based cryptographic protocols for symmetric functions f: {0, 1}n → R, where R is an ...

The 15-puzzle is a puzzle game played with 15 square tiles numbered from 1 to 15 on a 4 × 4 board. It has been popular for generations because of its simplicity and challenge. The (w × h)-puzzle is a generalization of the 15-puzzle, which is played with ...

Wireless charging standard Qi is widely used, especially for smartphones, thanks to the convenience of charging the device simply by placing it on the charger. However, wireless charging has several security concerns. There is a great risk of making ...

Designated Verifier Signature (DVS) is an extension of digital signature that allows the specification of the verifier. This feature is realized by granting the designated verifier the privilege of simulating a valid signature, thereby virtually ...

In CRYPTO 2021, Han et al. proposed a PKI-based authenticated key exchange (AKE) scheme that satisfies tight security in the standard model by using KEM and digital signature with multi-user security as building blocks. On the other hand, no tightly ...

SNOVA is a multivariate signature scheme submitted to the additional NIST PQC standardization project started in 2022. SNOVA is constructed by incorporating the structure of the matrix ring over a finite field into the UOV signature scheme, and the core ...
