Description

Method and terminal for transmitting authentication information

The present application claims priority to Chinese Patent Application No. 201410138618.4, filed on Apr. 8, 2014, the entire disclosure of which is incorporated herein by reference. In this application.

According to the way of transmitting authentication information, the direct communication between the vehicle and the car, the vehicle and the infrastructure can be divided into two categories: the direct communication method of carrying the authentication information and the direct communication mode of the cellular assistance sending the authentication information.

In the direct communication mode (self-carrying straight-through) of the authentication information, the transmitting end carries the authentication information in the sending message, and after receiving the message sent by the sending end, the receiving end is effective according to the authentication information contained in the message. The identity is authenticated, and if the authentication is passed, the message is considered to be a valid message, otherwise the received message is considered to be an invalid message.

In the direct communication mode (cellular assisted straight-through) in which the cellular assists transmission authentication information, the security verification at the transmitting end can be assisted by the cellular network. Specifically, the sending end sends the authentication information to the base station, and the base station may send the authentication information of the sending end to the receiving end after performing security verification on the transmitting end according to the authentication information, or directly forward the authentication information of the sending end.

detailed description

Before describing the embodiments of the present application in detail, the concepts involved in the embodiments of the present application are first introduced.

Carrying a straight-through type by itself: direct communication mode of carrying authentication information;

Cellular assistance straight-through: Cellular assistance to send authentication information directly to the communication method;

First terminal: currently using a cellular assisted straight-through terminal;

a first direct communication message: a direct communication message sent by the first terminal and sent by the second terminal;

a second direct communication message: a direct communication message sent by the first terminal to the second terminal;

Second terminal: a terminal that transmits a first direct communication message.

Wherein, the first direct communication message and the second direct communication message are messages transmitted between the terminals in the car network system, for example, a point-to-point communication message between the car and the car, the car and the infrastructure, and a road sent by the car and the infrastructure. Security messages, etc.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The method for transmitting the authentication information provided by the embodiment of the present application is as shown in FIG. 1 , and specifically includes the following operations:

Step 100: After receiving the first direct communication message, the first terminal determines a communication mode used by the second terminal that sends the first direct communication message.

Step 110: If the second terminal adopts the straight-through mode, the first terminal carries the authentication information in the second direct communication message sent to the second terminal.

The authentication information carried in the second direct communication message is used to verify the validity of the second direct communication message.

Preferably, if the second terminal adopts the self-contained straight-through type, the first terminal not only carries the authentication information in the second direct communication message sent to the second terminal, but also sends the direct communication message to other terminals, broadcast, and multicast. It also carries authentication information.

The following description of the step 110 is also applicable to the case where the first terminal sends a direct communication message to other terminals, and the direct communication message is broadcasted and multicasted, which will not be described again.

The specific content of the authentication information may be determined according to actual needs, for example, may be the public key of the direct communication message sending end. CA signature and more. This application does not limit the specific content of the authentication information. Any information that can verify the validity of the direct communication message can be used as the authentication information.

After the step 110, if the first terminal determines that there is no terminal that directly carries the direct communication by itself, and the first terminal determines that it still uses the cellular assistance straight-through direct communication, the second direct communication sent by the first terminal will be stopped. The message carries authentication information.

Specifically, the first terminal may determine, according to the received direct communication message, whether there is a terminal that directly communicates by using the straight-through type by itself. The first terminal may also determine, according to the received indication information, whether there is a terminal that uses the self-contained direct-traffic direct communication, and the indication information is used to indicate whether there is a terminal around the first terminal that uses the self-contained straight-through to perform direct communication.

In the above process, if the second terminal adopts the cellular assistance straight-through, the first terminal still sends the second direct communication message according to the cellular assistance straight-through, that is, the second direct communication message does not carry the authentication information.

If the first terminal carries the authentication information in the second direct communication message, it preferably indicates that the communication mode is the cellular assistance straight-through in the second direct communication message, or is still indicated in the second direct communication message. It is capable of using cellular assisted straight-through.

The first mode, if the communication mode indication information is carried in the direct communication message, the first terminal determines the communication mode adopted by the second terminal according to the communication mode indication information carried in the first direct communication message.

The communication mode indication information may be implemented by using a bit mapping manner, or may be implemented by using an enumeration method, and may be implemented by other methods, which is not limited in this application.

Manner 2: If the direct communication message uses different information organization formats in advance or in different communication modes, the first terminal determines the communication mode adopted by the second terminal according to the information organization format of the first direct communication message, and different communication modes. The corresponding information organization format is different.

In the communication mode, what kind of information organization format is used for the direct communication message, which is not limited in this application.

The third mode determines the communication mode adopted by the second terminal according to the location information of the second terminal carried in the first direct communication message, if the location information of the second terminal is carried in the first direct communication message.

The specific manner of determining the communication mode used by the second terminal according to the location information may be determined according to an actual application. For example, pre-defined or agreed, as long as the terminal is located within the coverage of the cellular network, then cellular assisted straight-through, otherwise Carry a straight-through formula with yourself. Then, if it is determined that the second terminal is located in the coverage of the cellular network according to the location information, determining that the second terminal adopts a cellular assistance straight-through, and if it is determined that the second terminal is located outside the coverage of the cellular network according to the location information, determining that the second terminal adopts itself Carry straight-through.

Based on any of the foregoing method embodiments, preferably, if the second terminal adopts the self-contained straight-through, the first terminal determines that the second terminal meets the preset condition before sending the second direct communication message to the second terminal.

Among them, the reliable coverage of the cellular network refers to the range in which the signal of the cellular network can reach a predetermined strength. The size of the reliable coverage of the cellular network can be determined by the protocol or determined by the terminal according to preset rules. For example, an area within a predetermined distance from a cellular base station is defined as a reliable coverage of a cellular base station.

Specifically, if it is determined that the second terminal is capable of feeding back valid response information for the behavior query information or the status query information sent by the first terminal, determining that the second terminal meets the preset condition.

When the second terminal is within the reliable coverage of the cellular network, cellular assisted direct communication should be used. However, in some cases, if the cellular base station corresponding to the location of the second terminal is too large to provide the cellular assisted direct mode, the second terminal can only adopt the direct mode. When the first terminal sends the behavior query information or the status query information to the second terminal, the second terminal feeds back the valid response information; or the second terminal actively carries the situation in the sent message in the sent message.

Based on any of the foregoing method embodiments, preferably, the first terminal, in the second direct communication message that is sent, carries the indication information, where the indication information is used to indicate whether the second direct communication message carries the authentication information. Correspondingly, after receiving the second direct communication message sent by the first terminal, the other terminal currently using the cellular-assisted straight-through type determines the carrying of the authentication information according to the indication information carried in the second direct communication message. In this case, the direct communication message may be verified by using the authentication information carried in the direct communication message, or the direct communication message may be verified by using the authentication information sent by the cellular network. In this case, after the other terminal currently using the cellular assisted straight-through type receives the second direct communication message carrying the authentication information, it still assists in transmitting the authentication information through the cellular network according to the cellular assistance straight-through rule.

Based on any of the foregoing method embodiments, preferably, when the first terminal determines that the cellular assisted straight-through can not be continued, the first terminal switches the communication mode to carry the straight-through. The first terminal may determine whether the cellular-assisted straight-through can be used according to the message sent by the cellular network, and may refer to the existing implementation manner, which is not limited in this application. The first terminal may also determine that the cellular assistance straight-through can not be continued by receiving the setting information sent by the network side within a predetermined period of time.

For example, the terminal begins to be in an environment covered by cellular networks, using cellular assisted straight-through to send direct communication messages. The terminal receives the indication information sent by the base station, indicating that the network enters a congestion state; the terminal determines that the cellular assistance direct transmission is used to send the direct communication message; the terminal stops sending the authentication information to the base station, and starts to use the self-contained straight-through to send the direct communication message, that is, The terminal includes the authentication information in the sent-through message, and indicates in the direct communication message that the communication mode is a self-contained straight-through.

Based on any of the foregoing method embodiments, preferably, after the terminal is started or when carrying the straight-through type by itself, it is determined whether the cellular-assisted straight-through can be adopted according to the information sent by the received cellular network device; if the cellular-assisted straight-through can be adopted The terminal uses a cellular assisted straight-through type, otherwise, the terminal adopts a straight-through type of its own.

The terminal can periodically detect the information sent by the cellular network device to determine whether it can adopt the cellular assistance straight-through.

Specifically, the cellular information can be used to determine whether the terminal can adopt the cellular assistance straight-through according to whether the terminal can receive the indication information sent by the cellular network device, and the indication information is used to indicate whether the terminal can adopt the cellular assistance straight-through. It is also possible to determine whether or not it is possible to use the cellular assistance straight-through according to whether a communication link that satisfies the needs can be established with the cellular network device.

For example, after the terminal is powered on, it searches for a designated cellular network (such as China Mobile's cellular network); after searching for a designated cellular network, it accesses the network, and sends an application for directly transmitting a direct communication message by using cellular assistance; the base station sends a confirmation to the terminal. The information allows the terminal to use the cellular assistance to send a direct communication message in a straight-through manner; after receiving the confirmation information of the base station, the terminal uses the cellular assistance to send a direct communication message in a straight-through manner; the terminal transmits its own authentication information to the base station (periodic); the base station receives the terminal After the reported authentication information is verified, the terminal is verified. After the verification is passed, the authentication information of the terminal is processed and sent to other terminals under the base station, and then forwarded to the neighboring base station.

For another example, the terminal A is in an environment without cellular network coverage, and uses the self-contained straight-through to send a direct communication message. The terminal periodically detects the cellular network signal; after detecting the cellular network signal, the terminal accesses the network, and sends an application for directly transmitting the direct communication message by using the cellular assistance; the base station rejects the application sent by the terminal, and indicates that the current cellular network is in the Congestion state; after the set time (10 minutes), the terminal starts to periodically detect the cellular network again, after detecting the cellular network signal, accesses the network, and sends an application for transmitting the through message using the cellular assisted straight-through; the base station to the terminal Sending an acknowledgement message, allowing the terminal to use the cellular assistance straight-through to send a direct message; after receiving the confirmation information of the base station, the terminal uses the cellular assistance to send a direct communication message in a straight-through manner, and sends its own authentication information to the base station (periodic); the base station receives the terminal After the reported authentication information, the authentication information of the terminal is processed (periodically) and sent to other terminals under the base station, and forwarded to the neighboring base station.

For the second terminal, if the received direct communication message carries the authentication information, the authentication information is used to verify the validity of the direct communication message, and if the direct communication message does not carry the authentication information, discard the Direct communication Message.

The technical solutions provided in the embodiments of the present application are described in detail below by taking a specific application scenario as an example.

As shown in FIG. 2, the vehicle terminal A currently adopts a direct communication mode in which the authentication information is carried by itself, and the vehicle terminal B currently uses the cellular assistance to transmit the direct communication mode of the authentication information.

The vehicle terminal may be an in-vehicle device, a mobile phone, a palmtop computer, a tablet computer, or the like.

The vehicle terminal A is the second terminal, and the vehicle terminal B is the first terminal.

The vehicle terminal A and the vehicle terminal B each broadcast a direct communication message (hereinafter referred to as a through message) during traveling.

It is assumed that the vehicle terminal A first receives the through message sent by the vehicle terminal B, and the communication mode indication information included in the through message transmitted by the vehicle terminal B determines that the vehicle terminal B adopts the cellular assistance straight-through formula and determines the through message sent by the vehicle terminal B. Without carrying the authentication information, since the validity of the through message sent by the vehicle terminal B cannot be verified, the vehicle terminal A discards the received through message without the authentication information.

The vehicle terminal B receives the through message sent by the vehicle terminal A, determines that the vehicle terminal A carries the straight-through formula by itself, and determines that the through message sent by the vehicle terminal A carries the authentication information. Then, the vehicle terminal B verifies the validity of the through message according to the authentication information carried in the through message sent by the vehicle terminal A, and adds the authentication information to the through message sent by itself, and carries the indication in the through message. The information is used to indicate that the authentication information is included.

The vehicle terminal A uses the private key to sign the transmitted through message and carries the signature information in the through message. In addition, the pass-through message carries the certificate of the vehicle terminal A, or the pass-through message carries the summary information of the certificate. The certificate contains the public key associated with the private key of the vehicle terminal A and the signature information of the certificate by the certificate authority (CA).

If the through message sent by the vehicle terminal A carries the complete certificate, the vehicle terminal B first verifies the signature information in the certificate in the through message according to the public key issued by the CA to determine the validity of the certificate. After the certificate is verified, the public key of the certificate is used to verify the signature information of the private key of the terminal A to verify the validity of the through message. After the verification is passed, the road safety information contained in the direct message is submitted to the upper layer for processing. If the pass-through message sent by the vehicle terminal A carries the certificate digest, the vehicle terminal B obtains the cached complete certificate according to the certificate digest, and then verifies the through-pass message according to the above procedure.

The authentication information carried by the vehicle terminal B in the sent-through message may be a complete certificate of the vehicle terminal B, and the certificate carries the public key associated with the private key and the signature information of the certificate, and the authentication information may also be Certificate summary.

After receiving the through message including the authentication information sent by the vehicle terminal B, the vehicle terminal A performs validity verification on the through message according to the authentication information, and delivers the through message of the verified vehicle terminal B to the upper layer. The specific verification process can refer to the above description.

As shown in FIG. 3, the vehicle terminal A currently adopts a direct communication mode in which the authentication information is carried by itself, and the vehicle terminal B is currently adopted. Use cellular to assist in the transmission of authentication information directly.

The vehicle terminal B receives the through message sent by the vehicle terminal A, and determines the vehicle terminal A to carry the straight-through type by using the communication mode indication information included in the through message sent by the vehicle terminal A, and determines that the vehicle terminal A transmits the pass-through message. Right information. The vehicle terminal B verifies the validity of the through message according to the authentication information carried in the through message sent by the vehicle terminal A. In addition, the vehicle terminal B determines that the vehicle terminal A is within the coverage of the cellular network according to the received location information included in the through message sent by the vehicle terminal A, and knows that the corresponding cellular network is not congested by other means. Then, the vehicle terminal B judges that the vehicle terminal A does not satisfy the predetermined condition, and therefore does not need to add the authentication information in the through message sent by itself, and still sends the through message in the current cellular assistance mode.

As shown in FIG. 4, the vehicle terminal A adopts a direct communication mode in which the authentication information is carried by itself, and the vehicle terminals B and C use the cellular assistance to transmit the direct communication mode of the authentication information.

The vehicle terminal A, the vehicle terminal B, and the vehicle terminal C each broadcast a direct communication message (hereinafter referred to as a through message) during traveling.

Although the vehicle terminal B adopts the cellular assistance straight-through type, after receiving the through message sent by the vehicle terminal A, the vehicle terminal B has carried the authentication information in the subsequent through message sent by itself.

The vehicle terminal B receives the through message sent by the vehicle terminal C, determines the communication mode indication information included in the through message sent by the vehicle terminal C, determines that the vehicle terminal C adopts the cellular assistance straight-through, and determines that the through message sent by the vehicle terminal C is not carried. The authentication information, the vehicle terminal B verifies the validity of the through message transmitted by the vehicle terminal C using the authentication information related to the vehicle terminal C received from the cellular base station.

The vehicle terminal C receives the through message sent by the vehicle terminal B, determines the communication mode indication information included in the through message sent by the vehicle terminal B, determines that the vehicle terminal B adopts the cellular assistance straight-through, and determines that the vehicle terminal B transmits the through message. The right information, the vehicle terminal C may select to verify the validity of the through message sent by the vehicle terminal B by using the authentication information related to the vehicle terminal B received from the cellular base station, or may select the carried in the through message sent by the vehicle terminal B. The authentication information verifies the validity of the through message sent by the vehicle terminal B.

Although the through message sent by the vehicle terminal B received by the vehicle terminal C includes the authentication information, the vehicle terminal B indicates that the cellular assistance is straight-through, so the vehicle terminal C does not need to add the authentication information in the through message sent by itself. , still use the original cellular assistance to send direct messages.
