ECDSA IP Core
The curves P-192, P-224, P-256, P-384, and P-521 specified in 'SP 800-186', which includes specifications for the generation of the domain parameters used during the generation and verification of digital signatures, are supported.
ECDSA IP cores consist of a cluster of IPs. VHDL is used as the Hardware Description Language of the IP Cores. The cluster includes TRNG, DRBG, MMI (Montgomery Modulo Inversion), BAM (Barret Reduction, Addition-Substruction, Multiplication) and ECC (Elliptic Curve Cryptograph) IP Cores. The use of TRNG IP Core and DRBG IP Core is recommended. ECC cores are configurable, and their number can be changed.
