Decentralized and Privacy-Preserving Key Management Model
Abstract
Data centralization and the growing rate of security breaches and identity fraud have led us to seek privacy-preserving and decentralized identity management solutions. The success of decentralized models, such as Self-Sovereign Identity, hinges on the positive-sum combination of usability and security. To support this goal, we propose a decentralized system capable of performing key management operations including key generation, key backup, and key recovery. In addition we propose our preliminary solution for a decentralized identity verification protocol. To this end, we design a digital wallet that relies on Shamir's Secret sharing scheme and blockchain technology, and we present a number of the security parameters affecting our model.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
