Mathematical and computer modelling. Series: Technical sciences| Summary: | This paper presents functions addresses substitutions «trick» combining with data substitutions. This computational technique allows to eliminate conditional branches and thus to improve timing results for many algorithms, such as elliptic curve arithmetic algorithms. In this paper proposed technique is shown on simplest examples of several elliptic curve point multiplication algorithms with multiprecision integers signed digit representations. But it can give better results combined with more complicated highly branched algorithms. |
