Secure VPN technology is only possible with the use of appropriate security systems such as encryption, digital signatures, digital certificates, public/private key pairs, non-repudiation, and time-stamping. A PKI comprises a system of certificates, certificate authorities, subjects, relying partners, registration authorities, and key repositories that provide for safe and reliable communicatio...

representations of context [24]. While previous work has mainly focused on interaction itself and specific context-sensitive behaviors, we explore a systematic approach to the notion of situatedness where our main concern is themultiple ways in which this notion can be captured, become readily available as a design resource, and decisively frame the design of the system. More specifically, we c...

Public-private partnership can be considered one of the most priority areas for development social and transport infrastructure, improving education healthcare systems, attracting private capital to economy. Effective implementation infrastructure investment projects within framework public–private allows state investors benefit, ultimately all citizens. State administrative levers should focus...

We introduce a variant of quantum signatures in which nonbinary symbols are signed instead bits. The public keys fingerprinting states, just as the scheme Gottesman and Chuang \cite{GC2001}, but we allow for multiple ways to reveal private key partially. effect this modification is reduction number qubits expended per message bit. Asymptotically expenditure becomes low one qubit give security p...
