Memory-Efficient Random Order Exponentiation Algorithm

Duc-Phong Le, Ali A. Ghorbani
2020 IEEE Access  
This randomized solution will inhibit attacks that allow operations to be distinguished from one acquisition.  ...  The proposed algorithm requires only (m+1) memory registers instead of (m+r), where r > m as recommended in Tunstall's algorithm. Namely, the proposed algorithm saves about half the memory registers.  ...  CONCLUSION In this article, we revisited Tunstall's random order m-ary exponentiation algorithm.  ...
