Decentralised self managed identity systems using distributed ledger technologies.

Abstract

This report presents the results of a PhD thesis focused on the creation of a decentralised and autonomous identity structure. This structure allows users not only to store their identities, but also to generate them autonomously, without the need for a trusted third party or an external validation structure. To implement this concept, the 3BI-ECC framework, a network system based on blockchain and the cryptographic advantages of elliptic curves, has been designed to establish a decentralised consortium network of self-generated identities. In addition, a new blockchain structure called NestedChain was created, which allows two types of information to be stored simultaneously: the identity of users through smart contracts and the certification elements of the network. The Nested-C protocol has also been developed, a new consensus protocol that improves the efficiency and security of storing transactions on the blockchain. In addition, solutions are proposed to preserve the integrity of the information in each smart contract and in its transactions with the theoretical scheme. This research aims to create decentralised environments where each user controls their information on the network, protecting both their identity and the privacy of their data, thus promoting user autonomy in the digital environment.
