Abstract
Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for data encryption and decryption. In example embodiments, a first cipher key and a second cipher key are obtained. The first cipher key comprises a vector of cipher elements, and the second cipher key comprises a set of indices corresponding to a subset matrix of a polarizing matrix. A cipher vector is generated by polar coding of a data vector based on the first and second cipher keys and the polarizing matrix. The data and cipher vectors are combined for encryption of the data vector.
