Security on Dynamic ID-based Authentication Schemes
Jingxuan Zhai,Tianjie Cao,Xiuqing Chen,Shi Huang 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.1
Dynamic ID-based authentication schemes based on password and smart card are widely used to provide two-factor authentication and user anonymity. However, these schemes have one or the other possible security weaknesses. In this paper, we analyze the schemes of Li et al. and Wang et al. published in recent years. After the analysis, we demonstrates that Li et al.’s schemes are vulnerable to off-line password guessing attack if the user’s identity is compromised, Li et al.’s scheme cannot withstand the impersonation attack and linkability attack, Wang et al.’s schemes cannot resist off-line password guessing attack if the attacker steals a smart card, Wang et al.’s schemes fail to provide forward security. Our result shows that none of the existing dynamic ID based authentication schemes can achieve all the desirable security goals.

An Improved User-Participating Authentication Scheme
Huang Shi,Tianjie Cao,Gao Caiyun 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.6
Authentication between user and server has become more and more important in the insecure network. Chen et al’s proposed a user-participating authentication scheme. The CAPTCHA techniques and visual secret sharing is used in their scheme. The scheme can complete mutual authentication and resist certain known attacks. But for password guessing attack and denial-of-service attack, it can not resist. Therefore, an improved scheme to eliminate these weaknesses is proposed in this paper.

The basidiomycetous edible mushroom Stropharia rugosoannulata has excellent nutrition, medicine, bioremediation, and biocontrol properties. S. rugosoannulata has been widely and easily cultivated using agricultural by-products showing strong lignocellulose degradation capacity. However, the unavailable high-quality genome information has hindered the research on gene function and molecular breeding of S. rugosoannulata. This study provided a high-quality genome assembly and annotation from S. rugosoannulata monokaryotic strain QGU27 based on combined Illumina-Nanopore data. The genome size was about 47.97 Mb and consisted of 20 scaffolds, with an N50 of 3.73 Mb and a GC content of 47.9%. The repetitive sequences accounted for 17.41% of the genome, mostly long terminal repeats (LTRs). A total of 15,726 coding gene sequences were putatively identified with the BUSCO score of 98.7%. There are 142 genes encoding plant cell wall degrading enzymes (PCWDEs) in the genome, and 52, 39, 30, 11, 8, and 2 genes related to lignin, cellulose, hemicellulose, pectin, chitin, and cutin degradation, respectively. Comparative genomic analysis revealed that S. rugosoannulata is superior in utilizing aldehyde-containing lignins and is possible to utilize algae during the cultivation.
