INTEGRASI DISTRIBUSI DATA RADAR MENGGUNAKAN TEKNOLOGI BLOCKCHAIN DAN KRIPTOGRAF

Abstract Currently, radar is widely used in various fields such as meteorology, military, police, shipping, aviation, agriculture, disaster, and research. Meanwhile, currently the use of radar is still in the form of sectoral, partial, and fragmented so that the use of radar data is only internal. With Indonesia's geographical condition which is very broad and the integration and distribution of radar data has not been maximized, this has resulted in the lack of geographic area of ​​Indonesia that is reached by radar. The use or exchange of radar data still uses client-server-based information technology, and with centralized storage which has information security and privacy risk factors that are vulnerable to being misused or exploited. In addition, there is the possibility of data loss which makes it difficult to get data back, even when you have implemented a backup system with cloud or other protection, there is still a risk of complete data loss when compared to implementing a decentralized platform. Therefore, it is necessary to integrate and distribute radar data with a decentralized platform so that the radar data is not sectoral, partial, and fragmented. The integration and distribution of radar data will later be able to maximize the use of cross-field radar so that one radar can be used more optimally for all fields including meteorology, military, police, shipping, aviation, agriculture, disaster, and research. One of the technologies that can be used for the integration of radar distribution is blockchain and cryptography.   Keywords: Radar, Blockchain, Cryptography.
