Software Evaluation for Second Round Candidates in NIST Lightweight Cryptography

Lightweight cryptography algorithms are increasing in value because they can enhance security under limited resources. National Institute of Standards and Technology is working on standardising lightweight authenticated encryption with associated data. Thirty-two candidates included the second round NIST selection process, their specifications differ respect to various points. Therefore, for each algorithm, differences expected affect algorithm's performance. This study aims facilitate design those according usage scenarios. For this purpose, we investigate compare 32 algorithm using software implementations. The results indicate that latency memory depend parameters nonlinear operations. In terms usage, a difference exists ROM but not RAM from our experiments ARM platform. We also discovered data size be processed efficiently differs padding scheme, mode operation, block size.
