Mobile communication networks need public key cryptosystems that offer both low computation cost and user authentication. Tatebayashi et al. showed a key distribution protocol for such networks at Crypto'89 based on low exponent RSA. This paper shows that their protocol is not secure. We also present two types of secure and efficient key distribution protocols.
