Abstract
Examples associated with distributed authentication are described. One example includes generating a paired public key and private key associated with a user. The private key is split into a set of shares, which are distributed to a set of devices associated with the user. A challenge is generated to authenticate the user to grant the user access to a resource upon receiving an authenticating response to the challenge. The challenge is distributed to members of the set of devices. Partial responses are received from members of the set of devices and combined into a group signature. The group signature serves as an authenticating response to the challenge when generated from partial responses received from a threshold number of members of the set of devices.
