SDH-XS-KE is a key echange protocol proposed in 2014. The protocol SDH-XS-KE improves the¡±Strong Diffie-Hellman-DSA Key Exchange (called SDH-DSA-KE)¡± proposed by Jeong and al. in 2007. First SDH-XSKE is designed in finite groups such that Z=pZ where p is a prime number. So, in this paper, we present the elliptic curves version of the protocol SDH-XS-KE %U http://www.ccsenet.org/journal/index.php/jmr/article/view/0/40134
