Title: ESTABLISHING SECURE COMMUNICATION OVER AN INTERNET OF THINGS (IOT) NETWORK
Abstract:
A method includes performing by at least one host entity implemented in a network, receiving an encryption key generated by a key server and a key identifier associated with said encryption key, generating a header comprising an information identifier associated with an information to be protected, the device identifier corresponding to the key server and the key identifier associated with the encryption key, encrypting said information using said encryption key and associating the header with the encrypted information, transmitting said encrypted information and the associated header to a receiving entity and transmitting an authorization information, said key identifier, and said header to the key server. Further, in response to determination that the receiving entity is authorized to access the encrypted information, the receiving entity decrypts the encrypted information using decryption key received from the key server.
