Abstract: Disclosed herein is a system for a secret sharing authentication. The system may include a secret sharing information management server, a client device, and a network device. The secret sharing information management server may store and manage an authentication key capable of being used for secret sharing authentication, by dividing the authentication key into a first secret sharing key shard and a second secret sharing key shard, and allocate the first and second secret sharing key shards. The client device may receive the first secret sharing key shard from the secret sharing information management server and construct an interest packet by using the first secret sharing key shards. The network device may receive the second secret sharing key shard from the secret sharing information management server, and process the interest packet received from the client device on the basis of an ICN(Information Centric Networking) method by performing secret sharing authentication using the second secret sharing key shard and the first secret sharing key shard comprised in the interest packet.
