+

+

+=== Curve25519 ===

+We need to create an accelerator or possibly a complete implementation of the Curve25519 EC based DH-excgange.  We should be able to look at some previous work:

+

+* http://eprint.iacr.org/2013/375 - NaCl on 8-Bit AVR Microcontrollers. Includes an iterative implementation of Curve25519

+* http://cryptojedi.org/crypto/index.shtml - The code to the implementation

+* http://nacl.cr.yp.to/ - The main NaCl library by DJB.

+* http://cr.yp.to/ecdh/curve25519-20060209.pdf - The Curve25519 paper by DJB.
