This paper introduces a secure and efficient hybrid scheme based on polar codes, called as HES-PC. The proposed HES-PC contains of two other mechanisms: a key encapsulation mechanism based on polar codes, called as KEM-PC, a data encapsulation mechanism based on polar codes, called as DEM-PC. In fact, the symmetric key is exchanged between the legitimate partners by exploiting the KEM-PC. Also, secure polar encoding/successive cancelation (SC) decoding is enhanced between the honest parties by using DEM-PC.
