Encipher of information on the basis of geometrical presentations

In this paper, we examine a ciphertext on the basis of using geometrical objects. Each symbol normative alphabet is determined as a point on the plane. We consider possible ways for presentation of these points. The alphabet A is called normative, and symbols (letters) of the norma-tive alphabet is presented by natural numbers 1,2,. .. , L. As a rule, these numbers are represented in the binary scale of notation. Formally, the plaintext M is the ordered excerpts with repetition of elements of L-set A. The number of such excerpts [1]: L N and this number determines complexity of random writing M of symbols of the normative alphabet A. * Department " Computing systems and networks " East-Ukrainian national university named for V.
