First embodiment
The conference system aims to solve the problems that the existing process of joining a conference system by participants is complex, inconvenience is brought to users, and the user experience is low. The embodiment provides a conference joining control method, which may specifically refer to fig. 2:
first, it should be noted that the conference join request and control method provided in the embodiments of the present invention are applied to a terminal and a conference system supporting a neighbor induction network technology, that is, the embodiments of the present invention are based on a conference join request method and a conference join control method supporting a neighbor induction network.
Secondly, it should be noted that the conference joining request and control method provided by the embodiment of the present invention is applicable to various terminals, such as a portable terminal and a wearable device, where the wearable device specifically includes an existing ordinary bracelet, a flexible screen bracelet, and even a wearable mobile terminal, but these terminals are all devices that implement communication based on a neighbor sensing network technology.
S201: and acquiring a conference data frame to be sent in the conference system and a data encryption mode of the conference data frame when the conference data frame is sent.
In this embodiment, the conference data frame is mainly used to provide an encryption mode for the terminal to request for conference joining data, that is, the terminal needs to acquire a communication rule required by the conference system when the terminal wants to join in the conference system, specifically, the data encryption mode required by the conference system is used to encrypt the conference joining data.
It can be understood that the data encryption manner at least includes a conference scene identifier and a public key, where the conference scene identifier is mainly used to mark a data content type set in the conference data frame, for example, the conference scene identifier marks the public key identifier, after the public key identifier is written, the public key content corresponding to the public key identifier is written, and the public key content is used to encrypt the conference joining request data interacted between the conference system and the terminal.
S202: and packaging the data encryption mode into a conference data frame to obtain broadcast data.
First, it should be noted that the composition structure of the conference data frame is: attribute ID + Length + Attribute Body Field, where the Attribute Body Field is a custom Field. It can be understood that the step of encapsulating the data encryption mode refers to writing the conference scene identifier in the data encryption mode and the public key corresponding to the conference scene identifier into the Attribute Body Field respectively, and in the writing process, the original custom Field needs to be split and expanded to expand the conference scene identifier Field and the conference content Field, and the conference scene identifier and the public key corresponding to the conference scene identifier are written into the two expanded fields correspondingly, so that the broadcast data is obtained. Specifically, the format of the conference data frame is as follows: attribute ID + Length + SubID + Variable, where the SubID corresponds to a conference scene identification field, and specifies the specific content of information written in Variable by the SubID, in this embodiment, the SubID writes a public key identification, and the corresponding Variable writes the specific public key content, for example, if the number 0 is the public key identification, the corresponding SubID writes the number 0 in the position of the SubID, and then writes the specific public key in the position of the Variable; or if the number 1 is the public key identifier, the corresponding number 1 is written in the Sub ID position, and then a specific public key is written in the Variable position. It should be noted that this is only an example, and in practical applications, the setting is flexibly performed by a developer according to experiments or experience, and it is understood that the conference data frame is different from the broadcast data in the change of the data content and the data structure.
In some other embodiments, in order to facilitate the terminal to extract the received broadcast data, the original custom field may be split and expanded in the process of writing the conference scene identifier in the data encryption manner and the public key corresponding to the conference scene identifier into the custom field, and the conference scene identifier field, the length field, and the conference content field are sequentially expanded, that is, the expanded length field is split and expanded between the conference scene identifier field and the conference content field, where the length field is used to identify the total length of the public key inserted in the conference content field, specifically, the conference data frame format: attribute ID + Length + SubID + SubLength + Variable.
In this embodiment, the method for encapsulating the data encryption mode into the conference data frame to obtain the broadcast data at least includes the following steps, which can be specifically shown in fig. 3:
s301: custom fields are extracted from the conference data frame.
It will be appreciated that the custom Field Attribute Body Field is extracted from the conference data frame.
S302: and dividing the custom field into a conference scene identification field and a conference content field.
For better understanding of the present invention, the custom Field Attribute Body Field is divided into a meeting scene identification Field Sub ID and a meeting content Field Variabl as an example.
It can be understood that the total length of the two divided fields, i.e., the conference scene identification field and the conference content field, is equal to the length of the custom field, and the content in the conference content field in the two extended fields should be obtained according to the content in the conference scene identification field, for example, the conference scene identification field in the present invention is a public key identification, and then after the conference scene identification field is a public key identification, the public key content must be written into the conference content field correspondingly.
S303: and inserting the conference scene identification into the conference scene identification field in the custom field.
In this embodiment, the conference scene identification Field is specifically a public key identification, and at this time, the public key identification is inserted into the conference scene identification Field Sub ID in the custom Field Attribute Body Field.
S304: the public key is inserted into the conference content field in the custom field.
Bearing the above example, further, the specific public key content corresponding to the public key identifier is inserted into the conference content Field Variable in the custom Field Attribute Body Field.
S305: and converting the inserted conference data frame into broadcast data.
Bearing the above example, further, the inserted conference data frame is converted into broadcast data, specifically, the frame format of the broadcast data is Attribute ID + Length + Sub ID + Variable, it can be understood that Sub ID corresponds to public key identification, and Variable corresponds to public key content.
S203: the broadcast data is transmitted to the terminal in a broadcast manner.
It can be understood that, in this embodiment, when broadcasting the broadcast data, the broadcast may be specifically implemented by a communication module in the conference system, and of course, in other embodiments, the broadcast may also be implemented by a gateway or a broadcasting device connected to the conference system. In fact, the present invention is not limited in any way as long as the broadcast data can be transmitted to the terminal in a broadcast manner.
S204: and receiving a conference joining request data packet encrypted according to the public key from the terminal.
In this embodiment, the conference system further receives a data packet requesting conference joining from the terminal, and it can be understood that the data packet requesting conference joining is obtained by the terminal from the broadcast data sent by the conference system, and the data packet requesting conference joining is encrypted according to the public key.
S205: the private key corresponding to the public key is used to decrypt the data packet requesting the conference join.
It should be clear that, in practical application, there is a public key set, and then a private key needs to be generated correspondingly, so that the conference system can decrypt the received encrypted conference joining request data. In this embodiment, the adopted encryption algorithm and decryption algorithm are implemented by selecting an asymmetric encryption algorithm, specifically, after the data encryption manner is encapsulated in the conference data frame, a corresponding private key needs to be determined according to the encryption algorithm corresponding to the public key and stored in the conference system, that is, while the public key is obtained according to the encryption algorithm, a corresponding private key is also output, the private key is known only by the conference system, and when the conference system receives a request that the terminal encrypts the public key obtained through the encryption algorithm to join the data packet in the conference, the conference system directly decrypts the conference by using the stored private key.
In this step, the data packet requested for conference joining is specifically a data frame composed of an attribute identification field, a length field and a custom field, and the format of the data frame may be the existing frame format or the frame format after expansion in the present invention.
In this embodiment, when decrypting the data packet requesting conference joining, the corresponding data content in the custom field in the data frame is specifically decrypted. When the data frame adopts the existing data frame format: when the Attribute ID + Length + Attribute Body Field, decrypting the data content in the Attribute Body Field byte by using a private key; when the data frame adopts the data frame format after the expansion of the invention: and when the Attribute ID + Length + SubID + SubLength + Variable or Attribute ID + Length + SubID + Variable, reading the content encrypted according to the public key from the data type in the Variable through the SubID identification, and further decrypting the content by using the private key.
It can be understood that the data content in the custom field in the data packet requesting the conference join is decrypted by using the private key to obtain conference level data, and the conference level data represents the level of the terminal participating in the conference, for example, the conference levels are divided into three categories, namely, leader, backbone and common staff from high to low.
S206: judging the legality of the decrypted data packet requesting the conference to join;
if the result is legal, step S207 is executed, and if the result is illegal, step S208 is executed.
In this embodiment, the validity of the decrypted data packet requesting the conference to join is determined, specifically, whether a conference grade obtained by decrypting data content in a custom field in the data packet requesting the conference to join is within a preset conference grade is determined by using a private key, if the conference grade is within the preset conference grade, the identity of the terminal is determined to be legal, the terminal is allowed to join the conference, and if the conference grade is not within the preset conference grade, the identity of the terminal is determined to be illegal, and the terminal is not allowed to join the conference.
It should be clear that the conference system will set the conference level of the employee with the terminal in advance, and the conference system will also store the conference level of each employee. For example, a company has 10 employees, each A, B, C, D, E, F, G, H, I, J, and the conference system divides employee A, B into leader classes, employee D, E, F into backbone classes, employee G, H, I, J into general employees, and stores the conference classes. It should be noted that the preset conference level is specifically set by the conference system manager according to the actual scene, and the present invention is not limited to the listed conference level.

It can be understood that, after the terminal joins the conference, the terminal may be further allocated with the corresponding conference resource according to the conference level obtained after decryption, that is, the conference system may also set the authority of the conference resource in advance for different conference levels, for example, the highest conference level is set as a leader, the authority of the conference resource of the leader is set as 100% of the important conference resource, the second highest conference level is set as a backbone, the authority of the conference resource of the leader is set as 80% of the important conference resource, the lowest conference level is set as a general staff, and the authority of the conference resource of the staff is set as 50% of the important conference resource. It should be noted that, in practical applications, the right to set conference resources for different conference levels is also set by the conference system administrator.
S208: and judging that the identity of the terminal is illegal, and not allowing the terminal to join the conference.
It can be understood that, when the conference level obtained by decrypting the data content in the custom field in the data packet requesting the conference to join is not within the preset conference level by using the private key, the identity of the terminal is determined to be illegal, and the terminal is not allowed to join the conference.
