Abstract
A system is provided that uses identity-based encryption (IBE) to allow a sender to securely convey information in a message to a recipient over a communications network. IBE public key information may be used to encrypt messages and corresponding IBE private key information may be used to decrypt messages. The IBE private keys may be provided to message recipients by an IBE private key generator. The IBE private key generator and the recipients who obtain their IBE private keys from that generator form a district. District policy information may be provided by the IBE private key generator that specifies which encryption and communications protocols are used by the district. The district policy information may also specify which authentication protocols are used by the district and may set forth how content-based protocols are implemented. This information may be used by senders in sending messages to recipients.
