METHOD OF CODING Russian patent published in 2011 - IPC H04K1/00 

FIELD: information technologies.

SUBSTANCE: method of coding includes the following sequence of actions: final group G is generated, message is formed in the form of element M of final group G, secret coding key is generated, cryptogram is generated in the form of element C of final group G by conversion of message M depending on secret key of coding, besides, as final group G a non-commutable final group is generated, secret coding key is generated in the form of two elements X and W of group G and multi-digit binary number e, cryptogram C is generated by formation of element R of final group G, equal to e extent of message M, i.e. R=Me, formation of element V of final group G depending on elements X and R of final group G and subsequent performance of group operation between elements V and W of final group G.

EFFECT: higher coding speed.
