Elliptic Curve Cryptography

The GRECC core is accessed via an AMBA APB slave interface. The core provides an interrupt to indicate when the encryption/decryption of a 233-bit block is completed. The sect233r1 elliptic curve domain parameters are specified in the “Standards for Efficient Cryptography (SEC) - SEC2: Recommended Elliptic Curve Domain Parameters” document. The document is established by the Standards for Efficient Cryptography Group (SECG). The B-233 elliptic curve domain parameters are specified in the “Digital Signature Standard (DSS)” document, Federal Information Processing Standards (FIPS) Publication 186-2. The document is established by the National Institute of Standards and Technology (NIST).

The GRECC can be used with algorithms such as:

• Elliptic Curve Digital Signature Algorithm DSA (ECDSA), which appears in FIPS 186-2, IEEE1363-2000 and ISO/IEC 15946-2

• Elliptic Curve El Gamal Method (key exchange protocol)

• Elliptic Curve Diffie-Hellman (ECDH) (key agreement protocol)

The IP can be implemented in any ASIC or FPGA technology. For specific information related to Xilinx, Microchip, and Lattice FPGAs, please refer to our dedicated web pages:

The IP core is available as a separate package or as an addition to commercial versions of the GRLIB VHDL library.
