The 4th embodiment:
Based on the general message authentication method that second embodiment provides, the embodiment of the invention provides a kind of concrete method that is used for message authentication, and the treatment state of message is confirmed.
As shown in Figure 6, a kind of sending method for message authentication of fourth embodiment of the invention comprises step:
Step S601: encapsulation is replied Start serial number, is replied serial number bitmap and bitmap as a result in the group acknowledge response message, replys with the affirmation of carrying one or more message;
Wherein: the described Start serial number of replying, the corresponding first serial number that needs the message of affirmation.The described serial number bitmap of replying, each expression is from described accepting state of replying the message that Start serial number begins.Described accepting state comprises the state of receiving and does not receive state.Described bitmap as a result, each expression is from described treatment state of replying the message that Start serial number begins.Described treatment state comprises to be handled correct status and handles error condition.
For example, for an application layer messages, if receive, then will reply bit position 1 corresponding in the serial number bitmap, if do not receive, then will reply bit position 0 corresponding in the serial number bitmap; For the application layer messages that receives, if handle correct, then with corresponding bit position 1 in the bitmap as a result, if handle mistake, then with corresponding bit position 0 in the bitmap as a result; For the application layer messages that does not receive, then as a result in the bitmap corresponding bit be set to a preset value, at all events value is represented not receive owing to reply bit corresponding in the serial number bitmap, its result is meaningless.
Receive, and the wrong application layer messages of processing causes owing to having exceeded recipient's disposal ability often.For example, RME disposes RSU, and wherein some configuration parameter has exceeded the disposal ability of RSU, will cause handling mistake.Again for example, 1000 messages of application layer messages indication buffer memory, and receiving terminal maximum cushioning ability has only 500 messages, also will cause handling mistake.
Described message serial number is used for the unique identification a piece of news.In an application example, described message serial number can add up since 0 circulation according to sending order, namely descends the message serial number of a piece of news to add 1, and numbering is started from scratch.
Particularly, can in message body, encapsulate and describedly reply Start serial number, reply serial number bitmap and bitmap as a result, and message header is set accordingly, finish the encapsulation of group acknowledge response message.General meeting encapsulated delivery parameter and message body attribute information in the message header, concrete according to predetermined encapsulation strategy setting, the present invention does not limit at this.
Wherein, the embodiment of the invention is supported adjustable length serial number bitmap and the bitmap as a result of replying, and described length of replying serial number bitmap and bitmap as a result is identical.Described reply the serial number bitmap and as a result the length of bitmap can arrange, for example, be placed in the service parameter, concrete figure place issues this configuration according to system configuration when networking.When described serial number bitmap and the described bitmap as a result of replying when all having only 1 bit, expression is returned ACK to single message, indicates accepting state and the treatment state of described single message.
Step S602: according to transmit leg and the recipient of described group acknowledge response message, and logic interfacing between the two, determine transmission path, finish the process of transmitting of described group acknowledge response message from transmit leg to the recipient.
Correspondingly, fourth embodiment of the invention provides a kind of method of reseptance for message authentication, as shown in Figure 7, comprises step:
Step S701: receive the group acknowledge response message;
Step S702: resolve described group acknowledge response message, obtain replying Start serial number, reply serial number bitmap and bitmap as a result;
Step S703: judge described each of replying in the serial number bitmap successively, when this position is designated as when receiving state, the result of corresponding bit indication in the analysis result bitmap;
Step S704: determine the treatment state of replying one or more message that Start serial number begins from described according to analysis result.
Namely, describedly reply N position indication accepting state in the serial number bitmap when receiving, N position in the corresponding described bitmap as a result is just effective, just resolves the N position in the described bitmap as a result, obtains beginning from the serial number of the first message that need confirm the result of N message; Describedly reply N position indication accepting state in the serial number bitmap when not receiving, the N position in the corresponding described bitmap as a result is invalid, does not resolve the N position in the described bitmap as a result of correspondence.
The embodiment of the invention adopts replys serial number bitmap indication accepting state, adopts the treatment state of bitmap indication as a result simultaneously, thereby can inform accurately that the opposite end application layer messages is in the concrete reception result of local terminal:
As a result 1: do not receive;
As a result 2: receive and handle correct;
As a result 3: receive and handle mistake.
Thereby make the opposite end to trigger corresponding processing policy according to The above results, better realize the application layer business.For example, when RME configuration RSU, when the group acknowledge response message that RSU returns to RME indicated the configuration messages of certain parameter not receive, RME can resend this configuration messages; If indicate the configuration messages of certain parameter to receive, but handle when wrong, represent that this parameter surpasses the disposal ability of RSU, RME can record, and adjusts this parameter, treats to issue again when RSU networks.Again for example, transmitting terminal requires 1000 messages of buffering, the group acknowledge response message that receiving terminal returns is indicated this buffering Indication message to connect and is received, but processing mistake, this may be owing to the buffer capacity that has exceeded receiving terminal causes, transmitting terminal can resend buffering indication message, requires the message amount of buffering to be reduced to 500, till receiving terminal can successfully be handled.Concrete processing policy is according to the setting of concrete application needs, and the present invention does not limit at this.
