In the Handbook of Applied Cryptography (Menezes, A. J.; van Oorschot, P. C. & Vanstone, S. A.) Protocol MTI/A0 key agreement (algorithm 12.53) described as $\mod p$-protocol. The survey Overview of Key Agreement Protocols (Ratna Dutta and Rana Barua) describes MTI/A0 as elliptic curve-protocol.
Unfortunately I have no access to original MTI article. How MTI-protocols were described originally?
