Abstract
It is well known in cryptography that it is easy to construct an unbreakable secret-key cipher system if a plaintext source generates letters which are independent and equiprobable even if the length of a key sequence is much less than the length of the message. In this paper, we suggest a new secret-key cipher system in which a message generated is transformed into two parts in such a way that the biggest part consists of independent and equiprobable bits and only this part is encrypted. The complexity of the method is exponentially less than that for other known methods
