Key generation and distribution method based on identity-based cryptography

A key generation and distribution system for an authentication framework for an operating provider network comprising an authentication entity and a service provider network comprising an authentication server, the key generation and distribution system comprising:

• a Network Identity Management (IDM), a User IDM and a Key Management Center (KMC) residing at the operating provider network;
• and a Service IDM entity residing at the service provider network, wherein
• the Network IDM comprises a processor, a memory, and instructions stored on the memory and executable by the processor to:
• receive a request for credential from the authentication entity, the request comprising an identity of the authentication entity;
• generate a new identity (ID) based on the identity of the authentication entity;
• transmit the new ID to the KMC;
• receive a secret key from the KMC;
• transmit the new ID and secret key to the authentication entity;
• the User IDM comprises a processor, a memory, and instructions stored on the memory and executable by the processor to:
• receive a request for credential from the Service IDM entity, the request comprising a plurality of identities;
• generate a new identity (ID) for each of the plurality of identities;
• transmit the new IDs to the KMC;
• receive a plurality of secret keys from the KMC, each of the plurality of secret keys correspond to one of the plurality of identities;
• transmit the plurality of new IDs and plurality of secret keys to the Service IDM entity;
• the Service IDM entity comprises a processor, a memory, and instructions stored on the memory and executable by the processor to:
• transmit a plurality of IDs to the User IDM;
• receive the plurality of new IDs and the plurality of secret keys from the User IDM
• distribute the plurality of new IDs and the plurality of secret keys to the authentication server and devices;
• the KMC comprises a processor, a memory, and instructions stored on the memory and executable by the processor to:
• receive the new ID from the Network IDM, generate the secret key, transmit the secret key to the Network IDM;
• and
• receive the plurality of new IDs from the User IDM, generate the plurality of secret keys, transmit the plurality of secret keys to the Network IDM.
