Аннотация:A vulnerability area of security infrastructures of the majority of existing distributed computing systems (DCS) is the need of operation of a fail-proof and tamper-resistant central server in the security infrastructure. In this work, we investigate the possibility of abandoning the special dedicated servers in the DCS security infrastructure and the use instead of them a distributed database on the basis of the blockchain technology, the paradigm of smart contracts and the Ethereum protocol. Since in this case the database of the security infrastructure is distributed across all the nodes in the system, this approach will increase the resiliency and security of DCS.
