This paper presents an effective analysis scheme for Diffuse Large B-Cell Lymphoma (DLBCL) microarray datasets. Analysis of variable (ANOVA) is a well known statistics tools. It is useful to get the oncogenes to distinguish the normal and cancerous tissues. But, it can not further obtain the sub-types...

Comments on Abe et al.'s Threshold Signer-ambiguous Signature Scheme from Variety of Keys

Yafen Chang, Chin-Chen Chang
In 2004, Abe et al. proposed a novel threshold signer-ambiguous signature scheme from variety of keys. Their scheme is a generalized case of the ring signature scheme. They claimed that their scheme allows the base signature schemes to be based on sigma-protocols, including Schnorr’s signature scheme,...

A secure and efficient scheme for authenticating remote users using smart card

Iuon-Chang Lin, Yang-Bin Lin, Chung-Ming Wang
In 2002, Chien, Jan, and Tseng proposed an e±cient and practical solution to remote authentication using smart card. However, in 2004, Hsu pointed out Chien, Jan, Tseng's scheme has a secure flaw that is vulnerable to parallel session attack. Therefore, in this paper, we improve Chien, Jan, Tseng's scheme...
