Testable security is a key concept in FIPS 140 standards. The application of this method to non-invasive attacks is a hot topic, both for FIPS 140-3 and forthcoming ISO 17825. This paper provides insights on relevant methodologies, based on realworld case studies. Our main point is that testing divides into two tasks, namely “leakage detection” and “leakage analysis”. The first task is by far t...

The jarosite family of minerals are part the alunite supergroup with general formula AB3(TO4)2(OH)6. Jarosite known to incorporate silver (Ag), but extent which this occurs, and at what temperature range, is not well constrained. To address knowledge gap, compounds A site filled K, Na, Ag H3O were synthesised 22 °C, 97 °C 140 simulate low-, moderate- high-temperature environments, respectively....

Side-channel attacks are easy-to-implement whilst powerful attacks against cryptographic implementations, and their targets range from primitives, protocols, modules, and devices to even systems. These attacks pose a serious threat to the security of cryptographic modules. In consequence, cryptographic implementations have to be evaluated for their resistivity against such attacks and the incor...

two peroxidases (ec. 1.11.1.7), pod i and pod ii were purified from the roots of cultivatedraphanus sativus l. var. cicil by one step ion-exchange chromatography after fractionation by acetone. the molecular weight of these enzymes were 43000 and 41000 daltons and rz 1.2 and 2.0 for pod i and pod ii, respectively. both enzymes consisted of a single polypeptide chain on sds-page. the maximum act...

Organisms in aquatic environments are exposed to a number of pollutants such as pharmaceutical residues. As such, the aim of the present study is to achieve the Lethal Concentration (LC50) of Povidone-iodine (Betadine) for Cyprinus carpio. To do so, the study employs samples, weighing 4±1 [mean±SD] gr, and carries out an experiment in static condition. Based on OECD instructions, after a period...
