Abstract
A device provides a one-time proof of knowledge about a one-time signing key to a server without revealing the one-time signing key by computing a hash as a hash function from the one-time signing key, and transmitting, to the server, the computed hash, an identity associated with the electronic device and a hash path of the hash. The server receives the message from the device and checks whether the hash corresponds to a one-time signing key for a root hash included in a public certificate associated with the identity, checks whether an index corresponding to the hash path from the one-time signing key to the root hash corresponds to a correct time slot, and determines it to be proven that the device is in possession of the correct one-time signing key when the checks are fulfilled.
