According to the abstract released by the Intellectual Property India: "The present disclosure provides a certificate-less authentication method (100) for resource-constrained devices. The method (100) includes initializing (102) a Private Key Generator server with a master secret key, generating (104) system wide public parameters using the master secret key, and publishing (106) the public parameters to clients in a network. The method (100) further includes receiving a request from a client for a partial private key associated with a user identity, authenticating (110) the user identity, generating (112) the partial private key using the master secret key and user identity, and transmitting (114) the partial private key to the client. The client generates a complete private key using the received partial private key and a locally generated random component. The method (100) performs encryption operations using recipient identities as public keys without requiring certificate validation and performs decryption operations using complete private keys."
