Isirova K. Models and Methods of Development of Decentralized Electronic Trust Services Based on Blockchain Technology and Post-Quantum Cryptography

The dissertation is devoted to the actual problem solution: models and methods of ensuring the stability and resilience of electronic trust services in the post-quantum period development. The dissertation’s purpose is to develop methods to ensure reliable and secure electronic trust systems operation through the use of blockchain technology and post-quantum cryptography. In the dissertation the main directions of new quantum-safe algorithms development are substantiated, it is shown that decentralized systems are able to better ensure the functioning of electronic systems in terms of increasing the range of electronic services and increasing the number of users, an improved model of decentralized Public Key Infrastructure is provided, an improved model of the electronic voting system, which differs from the existing ones in that it forms a depersonalized voter list without using blind signatures is presented, and an improved method of Winternitz one-time keys is developed.
