In this article the synthesis and analysis of group 2-digit cryptographic operations of addition modulo two have been done. We prove that the synthesized group of operations is the permutation group and shown its suitability for use in cryptographic transformation algorithms. The study found that many cryptographic operations of addition modulo two can be used for practical applications to expand the number of operations of a cryptographic transformation of the information.
