Abstract
A transmitting unit for transmitting data packets which contain useful information and corresponding receiving unit. The transmitting unit is configured to transmit multiple data packets successively. The transmitting unit is configured to generate and transmit a data packet with combined authentication information for a predefined number of transmitted data packets or for data packets which are transmitted in a predefined time period. The combined authentication information provides an authentication of the data packets of the predefined number of transmitted data packets or of the data packets that are transmitted in a predefined time period.

A transmitting unit for transmitting data packets which contain useful information, wherein the transmitting unit is configured to:
- transmit multiple data packets successively, and
- generate and transmit a data packet with combined authentication information for a predefined number of transmitted data packets or for data packets which are transmitted in a predefined time period,
- wherein the combined authentication information provides an authentication of the data packets of the predefined number of transmitted data packets or of the data packets that are transmitted in a predefined time period.
A receiving unit for receiving data packets containing useful information, wherein the receiving unit is configured to:
- receive multiple data packets successively from a transmitting unit and to forward said data packets for usage,
- receive a data packet with a combined authentication information item containing authentication information of a predefined number of data packets or of data packets transmitted within a predefined time period,
- authenticate the data packets already received and forwarded for usage using the combined authentication information, and
- carry out further steps based on a result of the authentication.
A system for transmitting and receiving data packets comprising:
- a transmitter configured to transmit multiple data packets successively, generate and transmit a data packet with combined authentication information for a predefined number of transmitted data packets or for data packets which are transmitted in a predefined time period,
- wherein the combined authentication information provides an authentication of the data packets of the predefined number of transmitted data packets or of the data packets that are transmitted in a predefined time period;
- and
- a receiver configured to receive the multiple data packets.
