An Overview of Block chain Concepts(In the security of the infrastructure of intelligence organizations)

The block chain has attracted a lot of attention in recent years and is one of the highlights. Researchers are still researching its scalability, security and stability. It has changed the way of life of many people in some areas due to the emergence of this emerging technology. Because the features of block chain technology ensure reliable and convenient services, we need to consider the security and privacy issues and challenges of this innovative technology. Block chain applications include financial services, healthcare, automobiles, internet of things , public and social services. Numerous studies have used the block chain data structure in various applications, however, a comprehensive review of the technical and practical context of block chain has not been performed.

The research method is content analysis and the way it is done is library and field and the results are a study of the role of block chain technology in the security of the infrastructure of intelligence  organizations. Also, the strategy of this research is in the form of content analysis that the sources used include: articles, scientific-research and internet searches in the field of block chain technology in different types.

In this article, we try to do a comprehensive review of block chain technology. The structure of the various algorithms, consensus, challenges and future opportunities for data security and privacy in the block chain were also discussed. From the point of view of communication security, it is concluded that the use of block chain technology in intelligence organizations is vital.
