Enhancing the security of password authenticated key agreement protocols based on chaotic maps
We demonstrate the weaknesses of the protocols of Xiao et al. and Guo and Zhang. We present two secure password-based authenticated key agreement protocols using chaotic maps. The proposed protocols prevent the weaknesses in previous protocols and reduce transmissions. The proposed protocols do not require extra equipments for storing long-term secrets in the client.
