    Secure Iot Update Using Blockchain
    (IEEE, 2021) Kaptan, Melike; Tomur, Emrah; Ayav, Tolga; Erten, Yusuf Murat
    In this study a platform is devised to send automatic remote updates for embedded devices. In this scenario there are Original Equipment Manufacturers (OEMs), Software suppliers, blockchain nodes, Gateways and embedded devices. OEMs and software suppliers are there to keep their software on Inter Planetary File System (IPFS) and send the meta-data and hashes of their software to the blockchain nodes in order to keep this information distributed and ready to be requested and used. There are also gateways which are the members of the blockchain and the IPFS network. Gateways are responsible for asking for a specific update for specific devices from IPFS database using the meta-data kept on the blockchain, and they will send those hashed secure updates to the devices. In order to provide a traceable data keeping platform, gateway update operations are handled as transactions in a second blockchain network which is the clockchain of the gateways. The system was implemented as of the two separate blockchain networks and it has been shown that, despite the calculation overhead of the member devices, by separating the functions between the two blockchain networks a more reliable and secure platform can be achieved.

    Blockchain : a Decentralized Approach To Big Data
    (Karabük Üniversitesi, 2018) Pehlivan Kaplan, Senem; Şahin, Serap
    The blockchain technology is a hot topic and a new technology in recent years. It is not only an underlying technology for many applications like Bitcoin application, but also it is a kind of thinking including cognitive and mental processing and understanding for artificial intelligence and human enhancement. All data or services are digitized. So, this leads to deal with big data. It is a challenge to deal with big data from the perspective of performance, scalability, availability and privacy in centralized systems. Blockchain is applicable to big data and brings different perspective how to process, store, read and write data. Also, the aim of this paper is to show that better solutions are possible in a decentralized way. Even the technology is in its early stages, the blockchain technology will be in future due to its superior features. Therefore, it is better to adopt this technology as soon as possible to place in future. This paper gives a brief about how the blockchain could approach to big data and analyzes existing information regarding the challenges of big data from the side of the blockchain.
