Evaluation of the reverse transformation methods complexity of the residual number system for secure data storage

The methods of conversion from the residual number system to the decimal number system based on the classical Chinese remainder theorem (CRT) and its improvements CRT I, CRT II are considered in this paper. Analytical dependences of the time complexity of the specified methods are analyzed and constructed. As the result of carried out investigation, it is established that CRT II is characterized by greater efficiency compared to the other methods mentioned above. Examples of the implementation of direct and reverse conversion of RNS based on the application of CRT , CRT I, CRT II are given.
