This paper examines new phenomenon and transformation that arise from the expansion of knowledge-based economy, envisions the meaning of e-government through comparing traditional administration with new governance, formulates the e-government model, and presents a direction for next e-government for the conclusion. These new phenomenon include a transformation to product and service convergence model, cyber sovereignty dilemma, privacy and information security threats, and various others. Also, there is a gradual transformation from government-oriented administrative approach to a new governance model that strengthens the role of NGO. And, e-government must work together to realize this new governance ideology. New e-government must be transformed where government and citizens can implement and manage e-government together. Therefore, expanding applications of Public Key Infrastructure (PKI) technologies, promotion of e-Democracy, and improvement of user interface to improve usability must be emphasized.

The three main purposes of this paper are to (1) identify critical success factors(CSF's) for electronic commerce(EC), (2) investigate the explanatory power of these CSF's on firm performance, and (3) compare differences in evaluating CSF's and explaining impact of CSF's on performance between Korean and U.S.A. EC managers. Through a literature review and interviews with managers in EC firms, a list of 16 CSF's consisting of 111 items was compiled. In the second stage, questionnaires were administered to managers of EC companies in Seoul, Korea and Texas, U.S.A. Survey results show that CSF's have very significant explanatory power for firm performance in both Korean and U.S.A. While security, privacy, technical expertise, information about goods/services, and variety of goods/services are the most explanatory CSF's in Korea, evaluation of EC operations, technical expertise, and ease of use show most explanatory power in U.S.A. This analysis confirms the fact that customers use EC if they feel comfortable about navigating EC for information about a variety of goods/services without technical difficulty and in a secure and private way.

Different from traditional auctions, electronic auctions provide a platform to allow bidders and auctioneers merchandise to each other over network anytime and anywhere. Auctioneers can publish information of goods, and bidders can choose the interested targets through this bidding platform. To ensure the fairness and security of electronic auctions, Li et al. have proposed a practical electronic auction scheme which can confirm the requirement of strong anonymity, bidding privacy, and secret bidding price. However, we have found out that Li et al.'s scheme may lurk the risk of the denial-of-service attack during the bidding phase in a sealed-bid auction. Thus, we propose a brand-new sealed-bid auction mechanism, in which the essentials of e-auction can be firmly preserved. In particular, each bidder only needs to register at the center once and then can join to multiple plays launched by different auctioneers. Moreover, the correctness of mutual authentication is confirmed according to the BAN logic model.

As a main component of Internet of Things (IoTs), the wireless sensor networks (WSNs) have been widely applied to various areas, including environment monitoring, health monitoring of human body, farming, commercial manufacture, reconnaissance mission in military, and calamity alert etc. Meanwhile, the privacy concerns also arise when the users are required to get the real-time data from the sensor nodes directly. To solve this problem, several user authentication and key agreement schemes with a smart card and a password have been proposed in the past years. However, these schemes are vulnerable to some attacks such as offline password guessing attack, user impersonation attack by using attacker's own smart card, sensor node impersonation attack and gateway node bypassing attack. In this paper, we propose an improved scheme which can resist a wide variety of attacks in WSNs. Cryptanalysis and performance analysis show that our scheme can solve the weaknesses of previously proposed schemes and enhance security requirements while maintaining low computational cost.

The objective of this study was to see how artificial intelligence applications affected organizational innovation in Jordanian commercial banks. Both independent and dependent variables were measured in three dimensions: expert systems, neural network systems, and fuzzy logic systems for artificial intelligence applications variable. Product innovation, process innovation, and management innovation for the organizational innovation variable. To achieve study objectives, a questionnaire was developed and distributed to a sample of one hundred fifty-three managers in Jordanian commercial banks, who were selected according to the simple random sampling method. Except for the neural network systems dimension, which comes in at an average level, the study indicated that there is a high level of organizational innovation and artificial intelligence applications. Furthermore, the findings revealed that artificial intelligence applications have a significant impact on organizational innovation in Jordanian commercial banks, with the most important artificial intelligence application being a fuzzy logic system. The study suggested keeping track of technological advancements in the field of artificial intelligence applications and incorporating them into banking operations by benchmarking with the best commercial bank practices and allocating a portion of the budget to technological applications and infrastructure development, as well as balancing between technology use and information security risks to ensure client privacy is protected.

Wireless Sensor Networks consist of small, inexpensive, low-powered sensor nodes that communicate with each other. To achieve a low communication cost in a resource constrained network, a novel concept of signcryption has been applied for secure communication. Signcryption enables a user to perform a digital signature for providing authenticity and public key encryption for providing message confidentiality simultaneously in a single logical step with a lower cost than that of the sign-then-encrypt approach. Ring signcryption maintains the signer's privacy, which is lacking in normal signcryption schemes. Signcryption can provide confidentiality and authenticity without revealing the user's identity of the ring. This paper presents the security notions and an evaluation of an ID-based ring signcryption scheme for wireless sensor networks. The scheme has been proven to be better than the existing schemes. The proposed scheme was found to be secure against adaptive chosen ciphertext ring attacks (IND-IDRSC-CCA2) and secure against an existential forgery for adaptive chosen message attacks (EF-IDRSC-ACMA). The proposed scheme was found to be more efficient than scheme for Wireless Sensor Networks reported by Qi. et al. based on the running time and energy consumption.

Information and Communication Technologies(ICTs) have substantially enlarged both the opportunities to realize one's human rights but have also resulted in the emergence of new challenges. ICTs are so deeply embedded and cental to almost all aspects of human activity. And ICTs are assuming an increasingly central role in all aspects of human and societal development across the world. But this is especially true of the right to privacy, which faces challenges such as profiling and data mining for public(including national security) and private purposes. ICTs access is a fundamental right for all humans in the information age. So we have need for regulation based on human rights in the digital age. And governments have a responsibility to protect individuals against violations of human rights and data protection by public authorities, but also by private entities. In addition, internet governance and multi-stakeholder principle have to be stressed on all of the internet issues because internet governance is included in the principle of democracy which have bottom-up communication and equality. So it is very importance that Internet Governance Forum is the space for a meaningful discussion on public policy issues relating to the internet.
