Among the most important and remarkable technological developments that have played an important role in the evolution of commercial exchanges at the national and international level is the emergence of digital currencies or cryptocurrency. The high capability of these cryptocurrencies in hiding the path of commercial exchanges and using peer-to-peer technology and removing the regulatory factor has caused a great desire to use these cryptocurrencies in criminal activities. On the other hand, this platform is a very suitable medium for the growth and development of criminal activities. The main issue is whether the entry of cryptocurrencies into Iran has had an effect on the increase in the volume of foreign exchange and goods smuggling and to what extent has this effect been? If the answer to this question is positive, the hypothesis of criminals using cryptocurrencies to facilitate their transactions is confirmed. To answer the question of this research, the ARDL method has been used, with the help of which data extracted from reliable statistical institutions have been analyzed. The results of the research show that the entry of digital currencies in Iran's economy has caused an increase in smuggling. The results show that the impact of using cryptocurrencies in smuggling is very high and can by long term be predicted up to 46%. Naturally, regulatory bodies should carry out the necessary supervision through possible channels, including service provider exchanges.

Based on the importance of using new technologies in Logistics, recently researchers focus on studies related in intelligent logistics. The role of intelligent logistics in effective supply chain management is increasingly critical, and researchers and practitioners have recently focused their attention in designing more systems to address today's challenges. One of the major challenges for military organizations in the logistics field is to utilize information technology to advance the speed of transmission and to find information and goods in a supply chain. The origin of all new technologies in the field of commercial and military information and communication technology is at the disposal of the intelligence and security organizations of the hostile countries, in which case, the logistical activities and support of the internal and external military organs of the country. Seriously, it has disrupted intelligence and security operations in addition to imposing sanctions or international threats on organizations by leaking military logistics information. Under such circumstances, security is a crucial logistics process for military organizations and organizations. Therefore, in this study, we intend to evaluate and identify the components of intelligent logistics cyber security by reviewing the modern scientific and research and military literature active in the military logistics industry and then using the expert assessment approach to evaluat the components in one of the most important and strategic industries. Finally, with regard to the identification of intelligent logistics security components and indicators, the identified requirements will be evaluated and analyzed using a questionnanire completed by experts.

Electronic payment systems, as one of the main components of electronic commerce, have seen a lot of growth worldwide in recent years, and governments, business owners, and institutions have provided their customers with a wide range of payment options by creating designed systems. Therefore, the purpose of this research is to present a model that can explain blockchain adaptations in order to reduce internet crimes in electronic payment portals.

The applied research was written in a descriptive-correlational survey type, which was completed, analyzed and measured by the branch employees of one of the country's banks using a standard questionnaire. The statistical population of the research is 77 people, according to Cochran's formula, the determined sample size is 64 people, and the result of Cronbach's alpha coefficient test to check the reliability of the questionnaire is 0.82.

Based on Mastercard's theories, the combination of traditional payment networks with blockchain-based networks has improved the security of electronic payment portals and reduced internet crimes, so in this research, in order to investigate the effects of independent research variables (security features, technical protections, ease of use, trust to the seller) on the dependent variables of the research (perceived security, perceived trust and the amount of use of electronic payments) a hypothetical model is designed based on the background of the research and the hypotheses indicate the causal relationships between the variables in the model.

The results show that the use of the new variable and the proposed model, in order to add law enforcement and supervisory institutions to verify the transactions during the transaction in order to prevent the occurrence of crime before the transaction, will improve the technology of electronic payment portals and create security in transactions and in The result will increase users' trust in electronic payment portals.

Nowadays, the significant growth of digital currencies has drawn too much attention to this phenomenon. In this regard, the legal analysis and how the legislators make policy as to this issue has become one of the main concerns of researchers in this field. One of the most important legal issues of digital currency is the analysis of its legal nature and also how the prevalence of these currencies affect the national security of the country. In this article, we have attempted to explain the nature of these currencies, how other countries treated them, and also how the Iranian legislator dealt with them. Then, we tried to examine how the prevalence of these currencies will affect the national security of the country. It seems that our legislator has not adopted any law regarding the digital currencies just like the conservative countries; it has taken a similar position to China as it has practically banned banks and financial and credit institutions from trading digital currencies. However, the lack of proper legislation in this area has left an open door to the negative effects on national security; It is because the prevalence of digital currencies requires the observation of asset control mechanisms. Therefore, the non-compliance with these requirements will damage the country’s economic system as a result of money laundering crimes and compromise the country to terrorism because of committing the crime of financing terrorism.
