Simple authenticated key agreement algorithm
Dong Hwi Seo, P. F. Sweeney · Electronics Letters · 1999
A password-based method is described which modifies the Diffie-Hellman key agreement protocol to provide user authentication. It is simpler than previously published schemes, prevents the man-in-the-middle attack and requires only two packets to agree on the secret session key. An optional exchange of two more packets allows the key agreement to be verified.
