Abstract

In this article a key encapsulation mechanism is presented which is based on squaring function, where the input element is from QR⁺_N, where QR⁺_N denotes the signed quadratic residue group, and N is a Blum integer. The article presents the soundness, the efficiency and the proof of CCA security of the proposed mechanism
