Abstract
A system and method for implementing CRYSTALS-KYBER cryptographic algorithms and CRYSTALS-Dilithium cryptographic algorithms using table-based Arithmetic-to-Boolean (A2B) masked share conversion that includes dividing an N-bit arithmetic share, used in at least one of a CRYSTALS-KYBER cryptographic algorithm and a CRYSTALS-Dilithium cryptographic algorithm, into k chunks each of an n-bit value in a logic shift processing element, applying a table-based A2B masked share conversion to each n-bit value chunk to generate Boolean shares having k chunks with an n-bit value, and concatenating the k chunks of the generated Boolean shares to generate a complete N-bit Boolean share.
