The source code of this directory correspond to the work Security and Efficiency Trade-offs for Elliptic Curve Diffie-Hellman at the 128-bit and 224-bit Security Levels, authored by Kaushik Nath & Palash Sarkar of Indian Statistical Institute, Kolkata, India, containing various 64-bit implementations of X25519. The implementations of Montgomery ladder are developed using 64-bit assembly language targeting the modern Intel architectures like Skylake and Haswell.
To report a bug or make a comment regarding the implementations please drop a mail to: Kaushik Nath.
- Please compile the
makefilein the test directory and execute the generated executable file. - One can change the architecture accordingly in the makefile before compilation. Default provided is
Skylake.
