Use cases of blockchain cryptographic hash functions for ensuring data monitoring integrity


This paper considers the problem of security needs and data integrity with transactions blocks system using. A blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating parties. Each transaction in the public ledger is verified by consensus of a majority of the participants in the system. And, once entered, information can never be erased. Based on that, this paper presents description of cryptographic hash-functions in the transaction block chain system. In the paper the author shows the feasibility of using transaction blocks in distributed database and gives description of the consensus plots. As a base of cryptographic side, the author described Merkle– Damgard construction as a method of building collision-resistant cryptographic hash functions from collision-resistant one-way compression functions. This construction was used in the design of many popular hash algorithms and interesting for us SHA. This algorithm can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. Moreover in the paper is highlighted methods for support of monitoring systems integrity. Monitoring data is generating during CM of technical objects, particularly while realization of “Digital Twins”. During CM realization in global networks, integrity ensuring becomes very important.
