Variant of OTP Cipher with symmetric key solution

The paper proposes a solution to construct symmetric–key cryptographic algorithms based on OTP cipher developed based on the cipher One – Time Pad (OTP). Advantages of the algorithms built according to the proposed new solution is to have secure and efficient implementation as OTP cipher, but the establishment, management - distribution and usage of keys are exactly the same as the Symmetric key cryptosystems in practice (DES, AES,...).
