Abstract
A method for securely transmitting packets on a wireless link is disclosed. This method advantageously uses a type II HARQ protocol. In a first step, a first version of a packet is transmitted, so that the receiver cannot decode it. The receiver generates a couple of public and private keys, and sends back to the transmitter a negative acknowledgment as well as the public key. The transmitter then transmits a second version of the packet, encrypted using the public key. The receiver tries to decode a combination of the first and the second versions of the packet. In case of success, a positive acknowledgment is transmitted to the transmitter and, in case of failure, the retransmission process is iterated.
