A method for enhancing information security in a wireless communications system comprises receiving a data or control bit sequence and a user identity sequence, performing a CRC operation on the data/control bit sequence to generate a CRC bit sequence, and masking the CRC bit sequence with the user identity sequence to generate a coded bit sequence according to a formula. The formula comprises a first equation and a second equation, and the second equation calculates a plurality of coded bits of the coded bit sequence according to most significant bits or least significant bits of the user identity sequence and the CRC bit sequence.
