Requirements Justification, Construction and Analysis of Perspective Symmetric Cryptographical Transformations on the Base of Block Cipher Codes

Theoretical and practical aspects of analysis and synthesis of perspective symmetric cryptosystems have been developed. Analysis of requirements for perspective symmetric cipher, in particular for cryptoresistability, operating speed and memory volume has been performed. Principles of synthesis of the modern block symmetric cryptographical transformations have been investigated, main results of the performed investigations have been presented.
