Section 3.2.2 says:

      do {
        base = H(max(Alice,Bob) | min(Alice,Bob) | password | counter)
        temp = KDF-n(seed, "Dragonfly Hunting And Pecking")
        seed = (temp mod (p - 1)) + 1

It should say:

      do {
        base = H(max(Alice,Bob) | min(Alice,Bob) | password | counter)
        temp = KDF-n(base, "Dragonfly Hunting And Pecking")
        seed = (temp mod (p - 1)) + 1

Notes:

A variable "seed" is passed to the function KDF-n before defined. It should be the variable "base" instead of "seed". The variable "base" is passed to KDF-n in Figure 1.
