Abstract
The invention relates to a security method (100) for a security system (200) of a vehicle (1) for activating at least one security-related function in the vehicle (1) by means of at least one data transfer (D) between a portable access device (10) and the vehicle (1).
Claims20
Security method for a security system of a vehicle, for activating at least one security-related function in the vehicle based on at least one data transfer between a portable access device and the vehicle,
- characterized by the following steps:
- a) determining at least one security feature according to a predetermined security mechanism,
- b) performing the data transfer so that at least one data unit with at least the security feature is transmitted from the access device to the vehicle,
- c) examining of the transmitted data unit based on the transmitted security feature according to the security mechanism in order to assign the data unit to the access device on-board, so that an examination result is determined;
- d) activating the security-related function depending on at least the examination result,
- wherein the data transfer is performed connectionless via a radio communication technology, namely via a cryptographically unprotected communication channel, so that a cryptographic protection is essentially provided by the security feature and/or the security mechanism.
Security method for a security system of a vehicle, for activating at least one security-related function in the vehicle based on at least one data transfer between a portable access device and the vehicle,
- characterized by the following steps:
- a) determining at least one security feature according to a predetermined security mechanism,
- b) performing the data transfer so that at least one data unit with at least the security feature is transmitted from the access device to the vehicle,
- c) examining of the transmitted data unit based on the transmitted security feature according to the security mechanism in order to assign the data unit to the access device on-board, so that an examination result is determined;
- d) activating the security-related function depending on at least the examination result
- wherein
- the data unit is transmitted unencrypted, at least on a transport-oriented level, and thus comprises at least unencrypted control and/or protocol information and/or at least partially unencrypted user data, in particular at least unencrypted user data information, wherein the data unit is conducted as a data packet, and the user data comprise at least the unencrypted security feature.
Security method for a security system of a vehicle, for activating at least one security-related function in the vehicle based on at least one data transfer between a portable access device and the vehicle,
- characterized by the following steps:
- a) determining at least one security feature according to a predetermined security mechanism,
- b) performing the data transfer so that at least one data unit with at least the security feature is transmitted from the access device to the vehicle,
- c) examining of the transmitted data unit based on the transmitted security feature according to the security mechanism in order to assign the data unit to the access device on-board, so that an examination result is determined;
- d) activating the security-related function depending on at least the examination result;
- wherein
- the security mechanism comprises at least one cryptographic method for determining at least one assignment, in particular an authenticity, of the data unit, wherein the cryptographic method is a digital signature method and/or is performed based on at least one random value and/or rolling code.
Security method for a security system of a vehicle, for activating at least one security-related function in the vehicle based on at least one data transfer between a portable access device and the vehicle,
- characterized by the following steps:
- a) determining at least one security feature according to a predetermined security mechanism,
- b) performing the data transfer so that at least one data unit with at least the security feature is transmitted from the access device to the vehicle,
- c) examining of the transmitted data unit based on the transmitted security feature according to the security mechanism in order to assign the data unit to the access device on-board, so that an examination result is determined;
- d) activating the security-related function depending on at least the examination result;
- wherein
- the data transfer occurs via a public advertising and/or broadcast mode, in particular a Bluetooth communication technology, so that the transmitted data units and/or user data, in particular also the security feature, are publicly evaluable and/or readable, by all receiving nodes of the vehicle.
Security system for a vehicle for activating at least one security-related function in the vehicle based on at least one data transfer between a portable access device and the vehicle, comprising:
- at least one receiving node on the vehicle, which is conducted to receive at least one data unit by the data transfer,
- at least one processing device which is conducted to examine the received data unit in order to assign the data unit to the access device on-board,
- wherein the examination occurs based on a security feature and/or a security mechanism of the data unit, and the security-related function can be activated depending on the examination, and wherein the data transfer is performed connectionless via a radio communication technology, namely via a cryptographically unprotected communication channel, so that a cryptographic protection is essentially provided by the security feature and/or the security mechanism.
