Proprietary cryptography is a term used to describe custom encryption techniques that are kept secret by its designers to add additional security. It is questionable if such an approach increases the cryptographic strength of the underlying mathematical algorithms. The security of proprietary encryption techniques relies entirely on the competence of the semi-conductor companies, which keep the...

With the need for more environmentally friendly transportation and wide deployment of electric plug-in hybrid vehicles, vehicle (EV) charging stations have become a major issue car manufacturers real challenge researchers all over world. Indeed, high cost battery energy storage, limited EV autonomy lifespan, time, fast infrastructure, significant impact on power grid are origin several research...

Radar sensors have been widely used to estimate speed and displacement of remote targets. A novel market for contactless radar sensing is emerging in the field automatization process analysis, where non destructive testing evaluation methods are desired. Here, modern systems offer various advantages over conventional since they enable contactless, continuous, cost-efficient measurement static o...

Nanogenerator has been a very important energy harvesting technology through directly deforming piezoelectric material. Here, we report a new magnetic force driven contactless nanogenerator (CLNG), which avoids the direct contact between nanogenerator and mechanical movement source. The CLNG can harvest the mechanical movement energy in a noncontact mode to generate electricity. Their output vo...

This paper describes and compares the usage of passwordbased authenticated key agreement protocols to establish a secure communication channel between terminal and contactless card. In particular, protocols of this kind are discussed for use in contactless ID cards. The aim of this paper is to discuss, for the first time, two cryptographic password-based protocols with respect to security, impl...

A novel approach for replacing mechanical probes used for wafer level testing with an optical contactless method for the application and extraction of test vectors from advanced silicon integrated circuits (ICs) is described. Experimental results demonstrate its feasibility, using a novel silicon light-emitting diode (LED) and silicon light sensors fabricated on the IC. The proposed method uses...
