Cryptanalysis of Yang-Wang-Chang's Password Authentication Scheme with Smart Cards

In 2005, Yang, Wang, and Chang proposed an improved timestamp-based password authentication scheme in an attempt to overcome the flaws of Yang-Shieh_s legendary timestamp-based remote authentication scheme using smart cards. After analyzing the improved scheme proposed by Yang-Wang-Chang, we have found that their scheme is still insecure and vulnerable to four types of forgery attacks. Hence, in this paper, we prove that, their claim that their scheme is intractable is incorrect. Also, we show that even an attack based on Sun et al._s attack could be launched against their scheme which they claimed to resolve with their proposal.Comment: 3 Page

Topology of the Bend Loci of Convex Piecewise Linear Functions

This short article serves as the appendix for [Tran and Wang, 2022]. We prove that a complete intersection of $n$ generic polyhedral hypersurfaces in $\mathbb{R}^d$ is $(d-n-1)$-connected for $d\geq 2, d>n$

Is Investment in Agricultural Research a Good Substitute for Price Support in U.S. Cotton?

This article examines the effects of R&D on cotton yield and relationship between R&D and commodity support programs. The results indicate that yield elasticities with respect to cotton R&D is around 0.2-0.5 based on different regions. It further indicates that R&D increases government expenditures when both commodity programs and R&D funding exist. However, if the future WTO Doha negotiations rules out the possibility of price support programs, increasing R&D funding may provide one of the solutions for farmers to recover their income with 5-6 years lag.cotton, R&D, commodity support programs, Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,

Removal of nitrogen pollutant from domestic wastewater

Water as a medium for waste transport would be easily contaminated by human activities. Many methods have been proposed to treat contaminated water to protect human health and biodiversity (Z. Daud et al., 2017). Due to upgrade the existing wastewater treatment plant facilities, the typically advanced technologies have been proposed to remove many types of pollutant, effectively (Tchobanoglous, Burton, & Stensel, 2004). The development of wastewater treatment plant needs to be considered leading economic indicators to have low operational and maintenance costs (Lewandowski, 2015; Shammas, Wang, & Wu, 2009). Aerobic digestion (AD) has been known since 1950 as biological wastewater treatment process to treat wastewater by removing the pollutants for instance colloids, organic compounds and suspended solids to avoid the excessive pollutants released into the receiving water (Shammas and Wang, 2007)
