ECDSA IP Cores perform digital signature generation and verification in compliance with the Elliptic Curve Digital Signature Algorithm (ECDSA) specifications defined in 'FIPS 186'. This standard specifies methods for digital signature generation and verification using the Elliptic Curve Digital Signature Algorithm (ECDSA).
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.
