Stream cipher is as an important part of symmetric crypto system. One-time-pad cipher is the basic idea for stream ciphers, which uses XOR operation on the plain text and the key to generate the cipher. This research proposes a new stream cipher called MINNSC, based on the encryption decryption process using natural numbers. For a chosen natural, number blocks of non-zero divisors are generated and used as the encryption keys. These non-zero divisors form a group, their distribution is quite a random in nature, and this randomness is the desired property of stream cipher.
