A signature-enabled Polar code encoder and decoder are provided. Signature bits are inserted in some unreliable bit positions. Different signature bits are inserted for different receivers. For a given codeword, only the receiver with knowledge of the signature can decode the codeword. Cyclic redundancy check (CRC) bits may be included in the input vector to assist in decoding.
