Securing Data Transmission Using Blockchain Technology For IOT Platform: A Survey

Abstract

blockchain is a new direction for data platform are very limited, IOT needs special protecting. The main idea behind using blockchain techniques for data confidentiality. Traditional technology for hidden data is dividing data into small security approach are not suitable for IOT platform, parts and store each part in block. The data block is because they need high powered resources. related to the previous by hash code which makes the chain. Blockchain techniques are suitable for large and small amount of data. Since sensors collect much data all the time and send to receivers over edge Blockchain technology is based on dividing data and make relation between the generated parts before applying any encryption or protection algorithm. This reduces time complexity and does not need high computing devices, which have limited resources, researchers start to use blockchain as a light technique specifications. Thus, blockchain is used on IOT platform. for protecting data transmission over the internet. Sensor communication over the internet platform called internet of things platform. In this paper we show some previous work of blockchain techniques based IOT platform. In addition challenges and future direction will be discussed.
