EC Ultra Elliptic Curve Cryptography Microprocessor


From the leader in elliptic curve cryptography (ECC) cores comes the fastest ECC accelerator yet. The TeraFire® EC Ultra family of semiconductor IP cores unleashes a new class of ECC performance, based on a breakthrough architecture for ECC acceleration. Athena has achieved extraordinary performance density with EC Ultra, yielding an impressive increase of almost 5X over Athena’s E5200.

Product Description

TeraFire® EC Ultra IP cores accelerate EC point multiplies and ECDSA signs and verifies over NIST P-curves. Configurations can include as many P-curves as needed or can eliminate unnecessary curves to save system resources. Any curve may be supported, including Brainpool curves and non-singlular Weierstrass curves with the optional Programmable Curves feature.

EC Ultra 8K is the fastest core in the EC Ultra family and is capable of per- forming an ECDSA P-256 verify in less than 132 μs at 500MHz. EC Ultra 4K and 2K offer the same outstanding performance density as EC Ultra 8K in more compact forms.
