Protecting Dilithium against Leakage

Transactions on Cryptographic Hardware and Embedded Systems, 2023
CRYSTALS-Dilithium has been selected by the NIST as the new standard for post-quantum digital signatures. In this work, we revisit the side-channel countermeasures of Dilithium in three directions.
