Mobile communication networks need public key cryptosystems that offer both low computation cost and user authentication. Tatebayashi et al. showed such 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 a new secure and efficient key distribution protocol.
