data encryption

На основі алгоритму RSA як найбільш вживаного промислового стандарту шифрування даних запропоновано модифікації з використанням проективних відо- бражень та афінних перетворень для шифрування зображень, що дають змогу строго виділяти контури.

Based on the algorithm of RSA, as the most common industry standard data encryption, proposed modifications using projective mappings and affine transformation for image encryption, allowing strictly allocate paths.

The requirements are formed, the method is chosen and the main stages of development of mobile means of neuro-like cryptographic encryption and real-time data decryption are considered. It is shown that the development of mobile means of neuro-like cryptographic encryption and decryption of real-time data with high efficiency of equipment is reduced to minimize hardware costs while providing a variety of requirements, characteristics and limitations. The tabular-algorithmic method of calculating the scalar product has been improved.

The system model of wireless technologies security was proposed on a level of the structure “system – signal – channel – tract” and its metrological support according to the conception “object – threat – defence”. The software of data encryption procedure for WiMAX systems based on AES standart and C# programming language was developed in limits of the created model.
