Faster fog-aided private set intersectionwith integrity preserving None

Qiang WANG, Fu-cai ZHOU, Tie-min MA, Zi-feng XU

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 12, Pages 1558-1568 doi: 10.1631/FITEE.1800518

Abstract:

Private set intersection (PSI) allows two parties to compute the intersection of their private setswhile revealing nothing except the intersection.To resolve this problem, we first propose a novel primitive called “faster fog-aided private set intersectionwith integrity preserving”, where the fog conducts delegated intersection operations over encrypted

fuzzy model for assessing the risk exposure of procuring infrastructure mega-projects through public-private

Albert P.C. CHAN, Robert OSEI-KYEI, Yi HU, Yun LE

Frontiers of Engineering Management 2018, Volume 5, Issue 1, Pages 64-77 doi: 10.15302/J-FEM-2018067

Abstract: Considering the rapid urbanization growth rate particularly in developing countries, the number of infrastructure mega-projects over the past years has risen tremendously. Essentially, because infrastructure mega-projects require huge investment funds, better management skills, well qualified and experienced international expertise and technology innovation, they are mostly preferred to be procured using the PPP method compare to the use of the traditional bid-build system. In this regard, this paper aims to develop a fuzzy evaluation model for assessing the suitability of procuring infrastructure mega-projects through PPP by considering their risk exposure. The main body of Hong Kong-Zhuhai-Macao Bridge (HZMB) is used as a case project to demonstrate the practicality of the risk evaluation model. The risk evaluation model consists of four critical risk groupings, these include, construction and land risks, commercial risks, operational risks and political risks. Using the risk evaluation equation, a risk index of 4.53 out of 5.00 is computed for the selected project if it is procured through the PPP scheme. This outcome shows that the case project is not suitable for the PPP approach because its risk exposure is very high. The model developed will enable PPP practitioners to predict the likely risk exposure of procuring infrastructure mega-projects through the PPP scheme.
