Monitoring power breakers using vibro acoustic techniques

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 3, Page # 1771–1776, 2017; DOI: 10.25046/aj0203216
Abstract:

Speaking about the commutation’s equipment, it can be said that the best solution in increasing reliability and lowering the maintenance costs is a continuous monitoring of the equipment. However, if the price/quality ratio is considered, it is obvious that, for the moment, the diagnosis can be also an acceptable solution. Nowadays the predictive maintenance for…

A Highly-Secured Arithmetic Hiding cum Look-Up Table (AHLUT) based S-Box for AES-128 Implementation

Advances in Science, Technology and Engineering Systems Journal, Volume 2, Issue 3, Page # 420–426, 2017; DOI: 10.25046/aj020354
Abstract:

Side-Channel Attack (SCA) is an effective method in extracting the secret key of cryptographic algorithms by correlating the physical leakage information with the processed data. In this paper, we propose an arithmetic hiding cum Look-up Table (AHLUT) based Substitution-Box (S-Box) in AES-128 cryptographic algorithm implementation to countermeasure against SCA. There are three key features in…
