On the security of Park et al.'s key distribution protocol for digital mobile communications
Narn-Yih Lee, Tzonelih Hwang · 2002
Park et al. (see Proceedings of EuroCrypto '93, p.T131, 1993) previously proposed an efficient key distribution scheme for digital mobile communications. Two attacks are given in this paper to show that their scheme is not secure enough for session key distributions. A modified protocol is proposed to avoid these weaknesses.
