Deniability is defined as a privacy property which enables protocol principals to deny their involvement after they had taken part in a particular protocol run. Lately, Chou et al. had proposed their ID-based deniable authentication protocol after proving the vulnerability to Key-Compromise Impersonation (KCI) attack in Cao et al.’s protocol. In addition, they claimed that their protocol is not...

Deniability enables protocol participants to deny their involvement after they have taken part in a particular protocol run. In this paper, we present the security analysis of a class of interactive deniable authentication protocols and a noninteractive one. For interactive protocols, we focus on a serial of pairings based protocols proposed by Chou et al and repaired by Lim et al. We point out...

the purpose of the present study was to examine differences in lifestyle factors such as physical activity among homosexual (gay or lesbian), bisexual, and heterosexual korean adolescents.the sample consisted of 74,186 adolescents from grades 7-12 (ages 12-18) who participated in the 8(th) annual korea youth risk behavior web-based survey in 2012. of this sample, only 11,829 provided enough inf...

Conditional independence testing is an important problem, especially in Bayesian network learning and causal discovery. Due to the curse of dimensionality the case of continuous variables is particularly challenging. We propose a Kernel-based Conditional Independence test (KCI-test), by constructing an appropriate test statistic and deriving its asymptotic distribution under the null hypothesis...

background: cancer-screening programs are effective in reducing cancer prevalence and mortality; however, cancer remains the leading cause of death in elderly people in korea. the aim of this study was to identify the factors associated with elders’ participation in the national cancer screening program (ncsp) and differences in screening rates by gender. methods: original data from the korea n...
