Digital supply chain development in blockchain technology using Rijndael algorithm 256

Abstract

Information hollering through electronic links occurs across organizational boundaries with interagency that allow automatic exchange of electronic data between partners in the supply chain. In digital data networks are usually sent by copying them from one place to another, one of the main problems in this case is to verify that the information received from the network is genuine and latest. Blockchain technology is considered to solve the data verification in the data authenticity problem independently, without having to take regardless of who or where the data came from. The application of blockchain fits perfectly with the digital supply chain as it leverages Internet technology as a system that connects all organizations involved in the supply chain. Blockchain consists of a set of data consisting of a chain of data packets where each block consists of several transactions in each block can be validated using cryptographic means, cryptography itself consists of two kinds of cryptographic symmetric and asymmetric cryptography. In this paper the application of blockchain uses cryptographic symmetric with Rijndael 256 algorithm which is famous for its easy resistance, speed and design. the results of discussions using technology and blockchain on the digital supply chain is still a concept of application. From the concepts, the researcher concludes the application of blockchain technology with the data structure can be applied by sharing encryption and can be applied in some cases, such as data verification for face recognition, artificial intelligence or machine learning.
