Abstract

A method for accessing a private key is provided. The method includes storing, by a first device, the private key and an associated public key, generating an access token, sending to a second device, the access token, sending, to a first server, an address relating to a decentralized identifier and the access token, sending, by the first server, to a ledger, a request for getting a decentralized identifier along with the decentralized identifier address. By way of the method a solution is provided for accessing, by a first server to be accessed from a second device, based on a decentralized identifier readable from a ledger, a second server, as a proxy to a first device. It allows for authenticating a first device to a first server while keeping the private key only at the first device side (and not at the second device side).
