A provable-secure and practical two-party distributed signing protocol for SM2 signature algorithm

Mobile devices are widely used for data access, communications and storage. However, storing a private key for signature and other cryptographic usage on a single mobile device can be challenging, due to its computational limitations. Thus, a number of (t, n) threshold secret sharing schemes designed to minimize private key from leakage have been proposed in the literature. However, existing schemes generally suffer from key reconstruction attack. In this paper, we propose an efficient and secure two-party distributed signing protocol for the SM2 signature algorithm. The latter has been mandated by the Chinese government for all electronic commerce applications. The proposed protocol separates the private key to storage on two devices and can generate a valid signature without the need to reconstruct the entire private key. We prove that our protocol is secure under nonstandard assumption. Then, we implement our protocol using MIRACL Cryptographic SDK to demonstrate that the protocol can be deployed in practice to prevent key disclosure.

Investigating online consumers’ responses to product presentation modes

Purpose With the proliferation of virtual reality (VR) applications in electronic commerce, investigations on the effects of VR on consumer responses are important. The purpose of this paper is to examine the effects of online presentation modes (i.e. situational VR, pure VR and picture) on consumer responses for three product types (i.e. geometric, material and mechanical). Design/methodology/approach This study conducted a 3×3 between-subjects experiment to validate the research model and hypotheses. Findings The results revealed that both the situational VR mode and the pure VR mode had a greater impact on product knowledge and purchase intention than the picture mode. The situational VR mode yielded a higher level of product knowledge and purchase intention than the pure VR mode although it was not statistically significant. Furthermore, the pattern of VR modes superiority was found to be consistent across geometric, material and mechanical product types. Originality/value This research study contributes to the VR literature by investigating a new type of VR: situational VR, and offering a more comprehensive picture of consumer responses to online product presentations. The authors then drew the implications from the findings to suggest guidelines for practitioners to efficiently allocate resources and maximize the effectiveness of online presentation modes.

An Empirical Analysis of Perceived Transaction Convenience, Performance Expectancy, Effort Expectancy and Behavior Intention to Mobile Payment of Cambodian Users

Mobile payment (m-payment) is determined as modern application of electronic commerce. It helps financial institutions to widen the financial services to existing customers in developed countries and to increase financial inclusion in developing and emerging countries. Cambodia is a country with low financial inclusion and National Bank of Cambodia perceives that the usage of m-payment can help to increase financial deepness. However, the lack of empirical evidences is a concern and this study is developed to fill the literature gaps. A research model as proposed in which behavior intention towards m-payment is affected by performance expectancy and effort expectancy. This model involves perceived transaction convenience as direct impact on performance expectancy and effort expectancy. Four research hypotheses were proposed and data was collected from 252 questionnaires. Obtained result showed that three hypotheses were supported. Only the effect of perceived transaction convenience on performance expectancy was not significantly. All factors qualified for reliability test’s requirement. EFA Analysis was conducted to verify the construct between factors and belonged items. Based on empirical results, recommendations and future researches were proposed.

ESTIMATION AND INFERENCE FOR VERY LARGE LINEAR MIXED EFFECTS MODELS

Linear mixed models with large imbalanced crossed random effects structures pose severe computational problems for maximum likelihood estimation and for Bayesian analysis. The costs can grow as fast as $N^{3/2}$ when there are N observations. Such problems arise in any setting where the underlying factors satisfy a many to many relationship (instead of a nested one) and in electronic commerce applications, the N can be quite large. Methods that do not account for the correlation structure can greatly underestimate uncertainty. We propose a method of moments approach that takes account of the correlation structure and that can be computed at O(N) cost. The method of moments is very amenable to parallel computation and it does not require parametric distributional assumptions, tuning parameters or convergence diagnostics. For the regression coefficients, we give conditions for consistency and asymptotic normality as well as a consistent variance estimate. For the variance components, we give conditions for consistency and we use consistent estimates of a mildly conservative variance estimate. All of these computations can be done in O(N) work. We illustrate the algorithm with some data from Stitch Fix where the crossed random effects correspond to clients and items.

The Role of Applications in the Support of Electronic Commerce �Application of Instagram as a Model� A sample of Members of Al-Kamil Community- Saudi Arabia

Background/Objectives: To identify the determinants of the practice of e-commerce in the full province. Methods/Statistical analysis: This study used 16 of previous researches as reference. The study was conducted on a sample of members of the full conservative society. The researcher used the descriptive analytical method to suit this study. • The existence of a relationship between the applications of e-commerce and the customs and traditions of the Saudi society in the province of Al-Kamil. • A statistically significant relationship between e-commerce applications and the comparative advantages and competitiveness of the organization. • There is an inverse relationship between the application of the information and the sale and purchase of products and services. The article recommended the following important issues: • Adopting the technology education policy for the members of the society in Al-Kamil governorate to demonstrate the importance of electronic commerce through training and education programs in professional and administrative institutions, with the aim of spreading technical awareness in educational and academic institutions in accordance with customs and traditions. • Resolving the obstacles facing the spread of e-commerce in non-civil societies by providing fast Internet, and raising awareness ofthe importance and benefits of e-commerce and keeping abreast ofthe global developments in the process of marketing products through the Internet. Findings: Instagram application is one of the best and most popular free applications used by users to share and share photos on the Internet, giving users the ability to take photos and video clips, and then share them through the various social networks and the network it. Last month, Windows Phone lacked many features and options, such as shooting videos, alerting users to people in the photos, and not allowing users to take pictures through the application. The researcher finds a set of recommendations calling for taking into account as a future work to be done by others:- • Adopting the technology education policy for the members of the society in Al-Kamil governorate to demonstrate the importance of electronic commerce through training and education programs in professional and administrative institutions, with the interest of spreading technical awareness in educational and academic institutions in accordance with customs and traditions. Improvements/Applications: Saudi Arabia is one of the societies of the modern world seeking technological revolution. For decades, Saudi Arabia has witnessed a great turnaround in the transformation of a technical society based on the advantages of communication technology in particular and modern technology in general in all fields. The concept of e-commerce since it has become a real reality, we must deal with it, but there is a significant reluctance in the practice of electronic commerce using applications, especially the application of the interest in the society of the province of full one of the provinces of Saudi Arabia. The benefits of Instagram are so many advantages that many people are aware of these benefits and are helping them make money. As well as the potential for social growth and development within this social network, it is also possible to attract ever-increasing numbers of followers.

Customers' Approach and Improvement Suggestions for Electronic Commerce Applications in Turkey

Günümüzde e-ticaret uygulamaları küresel çapta etkileyici bir şekilde büyüyerek nihai tüketicilerin sıklıkla tercih ettikleri bir alışveriş ortamı haline gelmiştir. Gelişmiş ve gelişmekte olan ülkelerin firmadan-müşteriye (B2C) doğru perakende e-ticaret işlem hacimlerinin yüksek olmasına rağmen, Türkiye’de ise benzer bir performans ortaya konulamadığı görülmektedir. Bundan dolayı bu çalışmanın amacı Türkiye’deki e-ticaret pazar potansiyelinin beklendiği düzeyde gerçekleşmemiş olmasının nedenlerini tespit ederek çözüm önerileri geliştirmektir. Bu doğrultuda, öncelikle sektör bazında yapılmış araştırmalar incelenmiş ve bu çalışmalardan faydalanılarak bir anket formu geliştirilmiştir. Daha sonra bu anket formu İstanbul’da e-ticaret müşterisi olarak tanımlanan, orta gelir düzeyinde maaşlı çalışan 312 kişiden oluşan örneklem kitlesine uygulanmıştır. Toplanan anketler neticesinde, örnek kitlenin e ticaret uygulamaları için harcadığı alışveriş bütçesi ile bu işlemler için ayırdığı zamanın çok düşük düzeyde olduğu görülmektedir. Buna karşın anket katılımcılarının e ticaret firmalarının performansını değerlendirilirken önem verdikleri unsurlar olarak satış sonrası hizmet kalitesi ve teslimat süresinin makul olması belirlenmiştir. E-ticaret uygulamalarıyla ilgili genel olarak müşterilerin en büyük çekincesiyse güvenlik algısı sorunudur. Bu sorunun üstesinden gelinmesi mikro ölçekte firma bazında değil ancak makro boyutta devlet ve sektörün hep birlikte hareket etmesiyle ele alınmalıdır. Bu doğrultuda Türkiye yerli milli siber güvenlik tedbirlerini geliştirmeli ve sektörde faaliyet gösteren firmalara yönelik yasal düzenlemeler oluşturmalıdır.

Identity-based undetachable digital signature for mobile agents in electronic commerce

To enable mobile agents signing securely on potentially malicious hosts in electronic commerce and other applications, we proposed the definition and security notion of identity-based undetachable digital signature schemes. More importantly, we proposed a concrete identity-based undetachable digital signature scheme with provable security. In the scheme, mobile agents need not carry the private key when they generate digital signatures on behalf of the original signer, so the private key will not be compromised. The encrypted function is combined with the original signer’s requirement, so misuse of the signing algorithm can be prevented. Moreover, because the scheme is identity-based, verification of the signatures generated by mobile agents does not require either verification of the entire certificate path or communication with the certification authority. Therefore, compared with existing undetachable signature schemes, the cost of verification is reduced and even the dependence on a stable network connection is weakened.

It is revolutionizing supply-chain management and has enormous potential for manufacturing, retail and service operations. E-commerce markets are growing at noticeable rates. The online market is expected to grow by 56% in 2015–2020. This paper shows the importance of E-commerce and define it and examines its major elements that link organizational systems. The application of EC in manufacturing, retailing and service operations is examined, and a framework for describing EC components and their role in different areas of an organization is proposed. The first part of the paper discusses challenges and new trends in supply chain business intelligence and provides background research of big data initiatives related to EC. The rest of this paper is from a discussion of the e-commerce impact on supply chain management and the advantages of supply chain management of e-commerce platform. The trend of e-commerce platform is proposed based on the development supply chain management. What will be the effect of the Internet on supply chain? What is the relationship between e-commerce and supply chain management?

Designing an Agent for Information Extraction from Persian E-shops

E-shops are among the most conventional applications of Electronic Commerce. In these shops, the buyers search for their goods through key words or classifications and read the product description provided by the sellers. Though, when the number of items is high, this gets to be difficult for the users. On the one hand, there are too many e-shops, and browsing in these shops to find the best and most appropriate goods is a difficult and time-consuming process. On the other hand, product descriptions are not the same in different websites, and there are different product forms. This study investigates about products and sellers in various websites based on the conditions and user requirements through software agents which present the extracted information in the form of a table to the users which enables them to compare prices and each seller’s conditions without spending too much time for browsing. Using this method increases precision and recall indices comparing to a conventional user browsing.

Bidding Behavior in Dutch Auctions: Insights from a Structured Literature Review

ABSTRACTThe Dutch auction, also known as the descending-price auction or reverse clock auction, has a long-standing history in practice and in academic literature. In practice, the Dutch auction is commonly used to rapidly sell large quantities of homogeneous goods, such as cut flowers, fish, or tobacco. However, most e-commerce auction sites focus on other auction mechanisms, and overall research on human behavior in Dutch auctions is scant. To facilitate research on Dutch auctions and their applications in electronic commerce, we conduct a structured literature review of experimental studies and establish the current state of research on bidding behavior in single-unit and multi-unit Dutch auctions. The findings are based on an analysis of twenty-nine articles published in the fields of economics, information management, marketing, and operations research and management science between 1970 and 2016. This review reveals (1) the characteristics that make the Dutch auction unique compared to other auction formats, (2) the drivers of bidding behavior in Dutch auctions, and (3) an overview of how Dutch auctions can be employed in practice and to what advantage. Finally, we identify directions for future research on bidding behavior in Dutch auctions.

A Secure ID-Based Blind and Proxy Blind Signature Scheme from Bilinear Pairings

ABSTRACTIn a blind signature scheme, the signer cannot link the relationship between the blind message and the signature of the chosen message. That is, blind signatures allow the user to obtain a signature of a message in a way that the signer learns neither the message nor the resulting signature. Therefore, it is very suitable for electronic commerce applications. A proxy signature allows the user to sign messages on behalf of the original signer. It is very useful when the original signer is not available to sign a specific document. A proxy blind signature combines the properties of both proxy signatures and blind signatures and is useful for e-cash and e-commerce applications. In this article, we propose a secure ID-based blind and proxy blind signature scheme from bilinear pairings. The proposed scheme satisfies the security properties of both blind and proxy blind signature scheme.

Data properties and the performance of sentiment classification for electronic commerce applications

Sentiment classification has played an important role in various research area including e-commerce applications and a number of advanced Computational Intelligence techniques including machine learning and computational linguistics have been proposed in the literature for improved sentiment classification results. While such studies focus on improving performance with new techniques or extending existing algorithms based on previously used dataset, few studies provide practitioners with insight on what techniques are better for their datasets that have different properties. This paper applies four different sentiment classification techniques from machine learning (Naïve Bayes, SVM and Decision Tree) and sentiment orientation approaches to datasets obtained from various sources (IMDB, Twitter, Hotel review, and Amazon review datasets) to learn how different data properties including dataset size, length of target documents, and subjectivity of data affect the performance of those techniques. The results of computational experiments confirm the sensitivity of the techniques on data properties including training data size, the document length and subjectivity of training /test data in the improvement of performances of techniques. The theoretical and practical implications of the findings are discussed.

Attacks on “a provably secure and efficient authentication scheme for access control in mobile pay-TV systems”

Mobile pay-TV systems represent an application of important electronic commerce, providing mobile users with the multimedia services. In 2016, Farash and Attari employed the elliptic curves and bilinear pairing technologies to design a one-to-many authentication scheme for mobile pay-TV systems. They claimed that their scheme provides a high level of efficiency and can resist most attacks on mobile pay-TV systems. In this paper, we point out their scheme cannot achieve the fundamental requirement of authentication that is, the mutual authentication. In addition, their scheme still suffers from three security weaknesses.

Industrial Cooperation of the EEA Member Countries in Perspective of the Digital Economy

Purpose: this paper is based on the research aimed at the assessment of capacity for industrial cooperation of countries of Eurasian Economic Union and consideration of the opportunities for industrial cooperation related to the technologies of the digital economy. Methods: the article is developed in accordance with the system approach, the system of general theoretical and economic methods: methods of positive and normative analysis, statistical methods of data processing and graphical presentation of information. Results: assessment of level and the capacity for cooperation in the industry of the EEU is presented. The role of the digital economy in industrial production is defined. The directions of strengthening the cooperation ties between the industrial enterprises of the EEA member countries using the capabilities of the digital economy are identified, as well as those factors that need to be taken into account when stimulating the relevant organizational and managerial innovations. It allows to develop the industrial policy measures within the framework of the EEA. Conclusions and Relevance: achievement of the goals of the EEA in the field of the industry is seen in the formation of a new paradigm of competition and cooperation of enterprises by deepening industrial cooperation through the introduction of the digital economy technologies. This provides a unique chance for overcoming the gap in the efficiency of industrial enterprises of the EEA member countries and enterprises of the leading countries emerged in the last quarter of a century based on competitive cooperation (coopetition). The results indicate that the EEA member countries have reached the depth of the division of labor in industry, which is expressed by a significant share of the exchange of intermediate goods, but the trend of further deepening of cooperation is not observed. Although by now the technologies of the digital economy have mostly found their application in electronic commerce and finance, the article identifies those that can and should become the foundation for innovations allowing to integrate elements of competition and cooperation of enterprises in the real sector of the economy.
