Description

Technical Field

[0001] This application relates to the field of trusted communication, and in particular to a token acquisition method, apparatus, device and medium based on dual-token index. Background Technology

[0002] Trusted communication technology, as a core technology for ensuring the authenticity of communication identities and data security, is essentially based on cryptographic engineering principles. Through the collaborative verification of digital certificates and identity tokens, it achieves trusted authentication of the calling terminal's identity throughout the entire call process. In practical applications, the called terminal needs to accurately obtain and visually display the true identity information of the calling terminal. This requirement not only aims to improve the user's caller ID experience but, more importantly, prevents security risks such as fake calls and fraudulent calls.

[0003] Currently, trusted communication systems generally rely on identity tokens to identify the calling terminal. Specifically, when a calling terminal initiates a call request to a called terminal, it generates a corresponding identity token and token index based on the current timestamp and uploads both to a token message transmission server. Upon receiving the call request, the called terminal generates a corresponding token index based on the current timestamp and then uses the token index to query the token message transmission server for the calling terminal's identity token.

[0004] However, in the actual operation of a trusted communication system, due to the transmission delay between trusted networks, the token index generated by the called terminal often cannot match the identity token uploaded by the calling terminal, which ultimately prevents the called terminal from presenting the true identity of the calling terminal and affects the implementation of trusted communication functions. Summary of the Invention

[0026] To address the technical problem in existing technologies where the token index generated by the called terminal is difficult to match the identity token uploaded by the calling terminal due to transmission delays between trusted networks, this application provides a token acquisition device based on dual token indexes. This device can eliminate the negative impact of transmission delays between trusted networks and ensure that the called terminal can successfully query the identity token uploaded by the calling terminal.

[0027] Figure 1 This is one of the flowcharts illustrating a token acquisition method based on a dual-token index, provided in an embodiment of this application. In one embodiment, the method is applied to a called terminal, and the method includes: S101-S105.

[0028] S101, Receive the call request from the calling terminal.

[0029] It should be noted that the calling terminal selects a type of identity information to initiate a call request to the called terminal. Next, the calling terminal generates a corresponding identity token based on the current timestamp and according to preset token generation rules. Then, the calling terminal generates a corresponding token index based on the current timestamp and according to preset token index generation rules. Finally, the calling terminal uploads the identity token and token index to the token message transmission server for the called terminal to download.

[0030] S102. Based on the first moment, generate the first token index according to the preset token index generation rules.

[0031] It should be noted that the first moment refers to the current timestamp of the called terminal. After receiving the call request from the calling terminal, the called terminal generates a first token index based on the current timestamp and according to a preset token index generation rule. The preset token index generation rule is as follows: tokenIndex = Hash(caller number || last three digits of called number || "@" || String(TimeCount)).

[0032] Where tokenIndex is the token index, Hash is the hash function (e.g., SM3), the calling number is the calling terminal's number, and the called number is the called terminal's number. "@" is the separator, and TimeCount is the time counter value, incrementing by 1 every minute. Specifically, the formula for calculating TimeCount is as follows: TimeCount = floor(current timestamp / 60). Here, floor is a function of the time count value.

[0033] It should be noted that the token index generation rules for the calling terminal and the called terminal are consistent. Based on the aforementioned preset token index generation rules, it is known that within the same minute, the token index generated by the calling terminal and the called terminal will be the same. When transmission delays occur in trusted network communication, this will cause the token index generated by the called terminal based on the current timestamp to be inconsistent with the token index generated by the calling terminal.

[0034] S103. Based on the second time point, generate a second token index according to the preset token index generation rules.

[0035] To address the issue of being unable to retrieve the calling terminal's token due to inconsistencies between the calling and called terminal's token indexes, this embodiment generates a second token index based on a second time point, according to a preset token index generation rule. The second time point is prior to the first time point, and the time difference between the first and second times points is determined by the preset token index generation rule. For example, if the preset token index generation rule determines that the tokens are generated within the same minute, generating the same token index based on the same calling and called terminal numbers allows the second time point to be set to one minute before the first time point, thereby eliminating the negative impact of trusted network transmission delays. In other words, the called terminal retrieves the calling terminal's identity token based on either the token index generated at the current time point or the token index generated based on the timestamp corresponding to the minute preceding the current time point. Put simply, the TimeCount calculated based on the timestamp corresponding to the first time point is one greater than the TimeCount calculated based on the timestamp corresponding to the second time point.

[0036] S104. Send a token request message to the token message delivery server.

[0037] The token request message includes a first token index and a second token index. The token request message is used to obtain the calling terminal's identity token. The identity token is matched against the call request.

[0038] It should be noted that after the token message transmission server receives the first token index and the second token index, it first uses the first token index to query the calling terminal's identity token. If the calling terminal's identity token is not found, it uses the second token index to query the calling terminal's identity token.

[0039] S105, Receive the identity token returned by the token message transmission server.

[0040] The token message delivery server returns the identity token of the calling terminal to the called terminal. Upon receiving the token, the called terminal extracts the calling terminal's identity information from the identity token and displays that information.

[0041] This application provides a token acquisition method based on a dual-token index. The method is applied to a called terminal and includes: receiving a call request from a calling terminal; generating a first token index based on a first time point according to a preset token index generation rule; generating a second token index based on a second time point according to the preset token index generation rule, wherein the second time point is before the first time point, and the time difference between the first and second time points is determined by the preset token index generation rule; sending a token request message to a token message transmission server, the token request message including the first token index and the second token index, the token request message being used to obtain the calling terminal's identity token, the identity token matching the call request; and receiving the identity token returned by the token message transmission server. Therefore, the technical solution of this application receives a call request from a calling terminal. Then, based on a first time point, a first token index is generated according to a preset token index generation rule. Furthermore, based on a second time point, a second token index is generated according to a preset token index generation rule. The second time point is before the first time point, and the time difference between the first and second time points is determined by the preset token index generation rule. Finally, a token request message is sent to a token message transmission server. The token request message includes a first token index and a second token index. The token request message is used to obtain the calling terminal's identity token, which matches the call request. Finally, the calling terminal receives the identity token returned by the token message transmission server. Therefore, the technical solution of this application employs a dual-token index mechanism: by generating two token indexes based on two consecutive associated moments, and using a parallel query method with dual indexes, the negative impact of transmission delays between trusted networks is effectively eliminated, ensuring that the called terminal can successfully query the identity token uploaded by the calling terminal using either the first or second token index.

[0042] In one embodiment, S104 specifically includes the following steps: S1041.

[0043] S1041. Send a token request message to the token message delivery server based on the UDP protocol.

[0044] It should be noted that the UDP protocol is used in this embodiment to send a token request message to the token message sending server.

[0045] The above S105 specifically includes the following steps: S1051.

[0046] S1051. Based on the UDP protocol, receive the identity token returned by the token message transmission server.

[0047] It should be noted that the UDP protocol is used in this embodiment to receive the identity token returned by the token message transmission server.

[0048] It should be noted that the UDP protocol is used to obtain the token data of the calling terminal in this embodiment, which effectively reduces the time overhead caused by the TCP three-way handshake. At the same time, a failure retransmission mechanism is added at the application layer to ensure that the token data of the calling terminal can be obtained even in a weak network environment.

[0049] In one embodiment, the method further includes: S106.

[0050] S106. If the called terminal does not receive the identity token returned by the token message transmission server, it shall send a token request message to the token message transmission server according to the preset retransmission mechanism and based on the UDP protocol.

[0051] The preset retransmission mechanism was set by the applicant based on practical experience. For example, the maximum number of retransmissions is 3. In this embodiment, if the called terminal does not receive the identity token returned by the token message transmission server, it sends a token request message to the token message transmission server according to the preset retransmission mechanism and the UDP protocol to ensure that the called terminal can receive the identity token returned by the token message transmission server.

[0072] The target token index is either the first token index or the second token index.

[0073] S303. If the identity token of the calling terminal is found, the identity token of the calling terminal is returned to the called terminal.
