Data verification protocol for a confidential computing scheme with homomorphic encryption

Abstract: Auction trading systems and Big Data technologies play an important role in modern society. However, as soon as these technologies deal with the finances of their users, there is a need to implement security systems in them to ensure the possibility of data verification. The article proposes a data verification pro-tocol based on the use of homomorphic encryption. A formal safety assessment of the developed protocol is shown, and an analysis from a probabilistic standpoint is carried out.
