A Novel DID Method Leveraging the IOTA Tangle and its Integration into OpenSSL

Abstract: This paper presents, for the first time, a novel Decentralized IDentifier (DID) Method called Over-The-Tangle and discusses its design and working principles that leverage the IOTA Tangle as the Root-of-Trust for identity data. The results of a long lasting experimental test campaign in real-world settings suggests the adoption of a private gateway node synchronised with the IOTA Tangle on the mainnet for efficient DID control. Moreover, the paper promotes the integration of the DID technology into OpenSSL through the use of Providers. A novel DID Operation and Provider is presented as a solution for building DID Method agility in OpenSSL.
