Claims70
A data transmitter for transmitting data to a data receiver, individual communication information being known to the data transmitter and to the data receiver, the data transmitter being configured to generate an individual synchronization sequence while using said individual communication information;
- said individual communication information being information which authenticates the data transmitter and/or information which authenticates a data packet of the data transmitter,
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
A data receiver for receiving data from a data transmitter transmitted by the data transmitter in a data packet, the data packet being provided with an individual synchronization sequence generated while using individual communication information known to the data transmitter and the data receiver, the data receiver being configured to generate an individual reference synchronization sequence while using the communication information and to detect the data packet to be received while using the individual reference synchronization sequence in a receive data stream or receive data buffer;
- said individual communication information being information authenticating the data transmitter and/or a data packet of the data transmitter;
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
A data transmitter for transmitting data to a plurality of data receivers, wherein individual communication information for individual communication between the data transmitter and the one data receiver is known to the data transmitter and to one data receiver of the plurality of data receivers, the data transmitter being configured to generate an individual synchronization sequence while using the communication information and to provide a data packet to be transmitted with the individual synchronization sequence for synchronization of the data packet in the data receiver;
- said communication information being information authenticating the data transmitter and/or information authenticating a data packet of the data transmitter;
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
A method for transmitting data to a data receiver, the method comprising:
- generating an individual synchronization sequence while using individual communication information known to the data transmitter and the data receiver;
- and
- transmitting a data packet comprising the individual synchronization sequence for synchronizing the data packet in the data receiver;
- said individual communication information being information authenticating the data transmitter and/or information authenticating a data packet of the data transmitter;
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
A method for receiving data from a data transmitter transmitted by the data transmitter in a data packet, the data packet being provided with an individual synchronization sequence generated while using individual communication information known to the data transmitter and the data receiver, the method comprising:
- generating an individual reference synchronization sequence while using the individual communication information;
- detecting the data packet in a receive data stream or receive data buffer while using the individual reference synchronization sequence;
- and
- receiving the detected data packet;
- said individual communication information being information authenticating the data transmitter and/or information authenticating a data packet of the data transmitter;
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
A method for transmitting an authenticated confirmation of receipt which confirms receipt of a preceding data packet transmitted by a first subscriber of a communication system, the method comprising:
- receiving the preceding data packet with a second subscriber of the communication system;
- and
- transmitting a data packet comprising an individual synchronization sequence from the second subscriber to the first subscriber upon successful receipt of the preceding data packet, the individual synchronization sequence being generated from individual communication information which is individually assigned to the first subscriber and the second subscriber for mutual communication;
- said communication information being information authenticating the data transmitter and/or information authenticating a data packet of the data transmitter;
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
A data transmitter for transmitting data to a data receiver, wherein individual communication information is known to the data transmitter and the data receiver, the data transmitter being configured to generate an individual synchronization sequence while using the individual communication information;
- said data transmitter being configured to derive the individual communication information from a preceding communication between the data transmitter and the data receiver;
- wherein the individual communication information is a cryptographic signature;
- or wherein the individual communication information is an encrypted part of the preceding communication;
- said individual communication information being known only
- to the data transmitter and to the data receiver, or
- to the data transmitter and to a group of data receivers.
