EBAKE-SE: A novel ECC-based authenticated key exchange between industrial IoT devices using secure element

Industrial IoT(IIoT)aims to enhance services provided by various industries,such as manufacturing and product processing.IIoT suffers from various challenges,and security is one of the key challenge among those challenges.Authentication and access control are two notable challenges for any IIoT based industrial deployment.Any IoT based Industry 4.0 enterprise designs networks between hundreds of tiny devices such as sensors,actuators,fog devices and gateways.Thus,articulating a secure authentication protocol between sensing devices or a sensing device and user devices is an essential step in IoT security.In this paper,first,we present cryptanalysis for the certificate-based scheme proposed for a similar environment by Das et al.and prove that their scheme is vulnerable to various traditional attacks such as device anonymity,MITM,and DoS.We then put forward an interdevice authentication scheme using an ECC(Elliptic Curve Cryptography)that is highly secure and lightweight compared to other existing schemes for a similar environment.Furthermore,we set forth a formal security analysis using the random oracle-based ROR model and informal security analysis over the Doleve-Yao channel.In this paper,we present comparison of the proposed scheme with existing schemes based on communication cost,computation cost and security index to prove that the proposed EBAKE-SE is highly efficient,reliable,and trustworthy compared to other existing schemes for an inter-device authentication.At long last,we present an implementation for the proposed EBAKE-SE using MQTT protocol.

Stock Market Development in Country With Least Development But Fast Economic Growth： A Case Study of Lao PDR

This paper aims to examine the market development evolution of Lao Securities Exchange （LSX） by observing the institutional structure, securities regulations, and government’s policy and utilizing the annual data of market indicators from 2011 to 2017 through the regression model in order to determine the facing issues with proposing the resolution implication for securities exchange development. The finding of this paper also concludes that the liquidity issue, small number of listed firms, undiversified products, small investor base, insufficient legislation from regulatory body, and slow progress in transforming state-owned enterprises （SOEs） into public companies are the current pressure obstacles for securities market development in Laos. In this case, there is a need for stronger commitment from government in securities market development by closer collaboration among line ministries, enlarging the investor base to public and private sectors, acknowledging the significance of drafting the public company act, and persuading the SOEs to issue initial public offering （IPO） in LSX, as the result would drive positive impacts to stimulate the capital market development in Lao People’s Democratic Republic （Lao PDR）.

Investor Relations （IR） in Business Communication on the Example of Poland

This paper focuses on investor relations （IR） as an element of companies＇ communication with the external environment. It shows the place and role of IR in communication with the general market, and the stock exchange market in particular. The study is illustrated with an example of IR in Poland, a relatively new European Union （EU） member state and an emerging market. As can be seen, IR goes beyond the traditionally understood maintenance of communication with the capital market. It is also shown that the main role of IR ought to be the reduction of investment risk and enhancement of the companies＇ value, which is of particular significance in light of the current globalization of capital markets. It has been found that Polish companies, especially those listed on the Warsaw Securities Exchange （WSE）, commonly rely on IR as a means of communication with the environment. And yet, as the results of the analysis show, the quality of that communication is still far from satisfactory, despite efforts undertaken by various external entities to encourage more focus on the development of IR, or understanding of the company＇s relevant staff of its important role.
