    IPC: H04L9/32

    Abstract: A method comprising: receiving, by a blockchain maintainer, a client request for a cryptographic token, the cryptographic token to allow the client to access a particular service from a service provider; processing, by the blockchain maintainer, the request using a blockchain smart contract to determine if the client request is valid; if the client request is determined to be valid, including the client request in the blockchain; generating, by a token issuer, the requested cryptographic token in response to inclusion of the valid client request in the blockchain; and issuing the generated cryptographic token to the client.

    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.

    Abstract: A system, comprising an authentication module to generate a challenge to authenticate a user, the challenge to be distributed to members of a set of verifying parties; and grant the user access to a resource upon receiving an authenticating response to the challenge; and a combiner module to receive partial responses from members of the set of verifying parties upon verification of the user by each member, the verification made using a provided contextual identifier of the user; based on the partial responses reaching a threshold number of responses, combine the partial responses to obtain a combined response, and provide the combined response to the authentication module as an authenticating response to the challenge.
