Rapidly Verifiable XMSS Signatures

Transactions on Cryptographic Hardware and Embedded Systems, 2020
This work presents new speed records for XMSS (RFC 8391) signature verification on embedded devices. For this we make use of a probabilistic method recently proposed by Perin, Zambonin, Martins, Custódio, and Martina (PZMCM) at ISCC 2018, that changes ...

Dissipation effects in spin-Hall transport of electrons and holes [PDF]

, 2004
We investigate the spin-Hall effect of both electrons and holes in semiconductors using the Kubo formula in the correct zero-frequency limit taking into account the finite momentum relaxation time of carriers in real semiconductors.
