Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A method for authenticated communication, the method comprising:
obtaining a first internet protocol (IP) packet;
modifying the first IP packet to form a modified IP packet, wherein modifying the first IP packet includes add an extension header to the first IP packet, the extension header including a first source identifier identifying the first device, an indication of a key generation authority, and an indication of a first identity-based cryptographic (IBC) algorithm;
generating a first identity-based signature (IBS) using the IBC algorithm with the first source identifier as an identity input, the modified IP packet as a message input, and a private IBC key for the first device as a private key input; and
sending the modified IP packet and the first IBS from a network interface towards a destination of the first IP packet.
