“…The model combined direct trust and indirect trust to derive trust values and considered the decay of friendship over time. Benkerrou et al [11] modelled node trust through credit value and proposed an IoT trust evaluation method based on trust and credit. Abderrahim et al [12] clustered the nodes with community interest and proposed a trust evaluation model based on community interest.…”

Smart city refers to the information system with Internet of things and cloud computing as the core technology and government management and industrial development as the core content, forming a large-scale, heterogeneous and dynamic distributed Internet of things environment between different Internet of things. There is a wide demand for cooperation between equipment and management institutions in the smart city. Therefore, it is necessary to establish a trust mechanism to promote cooperation, and based on this, prevent data disorder caused by the interaction between honest terminals and malicious terminals. However, most of the existing research on trust mechanism is divorced from the Internet of things environment, and does not consider the characteristics of limited computing and storage capacity and large differences of Internet of things devices, resulting in the fact that the research on abstract trust mechanism cannot be directly applied to the Internet of things; On the other hand, various threats to the Internet of things caused by security vulnerabilities such as collision attacks are not considered. Aiming at the security problems of cross domain trusted authentication of Intelligent City Internet of things terminals, a cross domain trust model (CDTM) based on self-authentication is proposed. Unlike most trust models, this model uses self-certified trust. The cross-domain process of internet of things (IoT) terminal can quickly establish a trust relationship with the current domain by providing its trust certificate stored in the previous domain interaction. At the same time, in order to alleviate the collision attack and improve the accuracy of trust evaluation, the overall trust value is calculated by comprehensively considering the quantity weight, time attenuation weight and similarity weight. Finally, the simulation results show that CDTM has good anti collusion attack ability. The success rate of malicious interaction will not increase significantly. Compared with other models, the resource consumption of our proposed model is significantly reduced.

Information management, an important element of which is the information system, has a direct impact on the functioning of a company, including its competitive position. Information management is related to the shape of the organizational culture, represented, inter alia, by the context of trust, relationship, and communication. The shape of the organizational culture, including the functioning of the information system, is particularly influenced by factors (usually external) that appear in a sudden and unpredictable manner. This impact increases with the intensity and scale of their influence. The recent COVID-19 pandemic should undoubtedly be considered such a factor. As a result, many enterprises suddenly had to switch to remote work. The aim of this paper is to analyze the essence and recognize the impact of the forced transition to a remote form of work on trust as a shaping and effective factor in the functioning of the company’s information system. To achieve this goal, the results of qualitative research conducted by the authors during the period March 2020–February 2021 and quantitative research conducted in February 2021 were used. In connection with the conducted research, it was found that trust is a very important factor influencing the efficiency and quality of employees’ work. It was also found that the forced need to switch to remote work mode was a problem for most people. This was influenced by both the time of the pandemic, as well as technical and organizational problems. As a result of observations, own experiences, interviews, and a questionnaire survey, the authors state that the necessity to switch from traditional to remote work resulted in an increase in the costs of functioning of people, including employees.
