In this paper, we introduce a new framework of password-based key exchange (PAKE). Until now, most PAKEs are based on smooth projective hash function on secure encryption. Our PAKE does not rely on smooth projective hash function, and consists of a variate lossy encryption, called only-one lossy enc...
