Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that, the technical solutions of the embodiments of the present application may be combined with each other, but it is necessary to use those skilled in the art as a basis, and when the technical solutions are contradictory or cannot be implemented, it should be considered that the combination of the technical solutions does not exist and is not within the scope of protection claimed by the present application.
Referring to fig. 1, a method flow diagram of an embodiment of a method for transmitting a 5G message is provided in the present application. The method may be performed by a sender terminal, which may be implemented in software and/or hardware. The transmission method of the 5G message comprises the following steps:
step S110: acquiring a 5G message edited by a sender user;
step S120: generating a signature result corresponding to the 5G message based on a key corresponding to an identity certificate of a sender user pre-stored in the sender terminal;
step S130: and transmitting the 5G message, the signature result and the identity certificate to a receiver terminal so that the receiver terminal can feed back the 5G message to a receiver user after verifying that the signature result and the identity certificate pass.
In this embodiment, the sender user is a holder of the sender terminal, and the sender user may edit a 5G message that needs to be sent to the receiver user through the sender terminal, and input the telephone number of the receiver terminal at the sender terminal when editing the 5G message.
The 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) message is an enhanced rich media short message, which may include text and pictures, and may also include information such as voice, video, files, geographic location, payment, etc., and may even call applications such as dials, calendars, etc. of the mobile phone. Through the 5G message, rich interactive services can be provided for users.
When a sender user transmits a 5G message, the 5G message can be uniquely identified by, for example, a telephone number ID1 of a sender terminal, a telephone number ID2 of a receiver terminal, a 5G message M, a time stamp T of message transmission, and the like.
Because the 5G message is realized based on the IP network and is not realized based on the traditional carrier non-open core network architecture, in the existing Internet product architecture, the data and the password of the user are stored in the service provider, and because the service provider can cause data leakage due to certain uncontrollable factors, if the 5G message is encrypted and protected at the sender terminal, the message can be further ensured not to be tampered or leaked. Specifically:
after acquiring the 5G message edited by the sender user, the sender terminal generates a signature result corresponding to the 5G message based on a key corresponding to the identity certificate of the sender user pre-stored in the sender terminal. The signature result contains the signature of the key pair 5G message, the telephone number of the sender, the telephone number of the receiver, the time stamp of message transmission and other information of the sender user, and the signature result and the identity certificate can be transmitted to the receiver terminal together with the 5G message.
The sender user can safely store the identity information in the sender terminal, the identity information can be in the form of an identity certificate or other identity certificates, for example, the identity information of the sender user can be a digital identity certificate in the format of X.509 and the like, and can also be other authoritative institutions or other certificates issued by specific public trust institutions, and the identity certificate and the certificates contain the trusted identity and public key information of the sender user so as to ensure that the receiver terminal can verify the signature information in the signing result based on the public key information. The identity information includes identity information of the sender user, for example, a work unit of the sender, a job position of the job, and the like.
The identity certificate of the sender user and the key information corresponding to the identity certificate may be stored in a relevant storage path of the sender terminal, for example, a local storage module of the terminal. The identity certificate and the corresponding key may also be stored in a memory module in the SIM card installed in the sender terminal.
After the 5G message, the signature result and the identity certificate are transmitted to the receiver terminal, the receiver terminal can verify the signature result and the identity certificate, wherein the identity certificate of the sender can be applied for downloading from the server of the identity information by the receiver terminal according to the related information of the signature result.
The receiving terminal verifies the signature result and the identity certificate by using the public key corresponding to the identity certificate of the sending party, and after the signature result and the identity certificate pass the verification, the verification result can be displayed on the receiving terminal, for example, the 'passing of the identity verification of the sending party' is displayed, and a 5G message is fed back to the receiving user, for example, the 5G message is put into an inbox, or the content of the 5G message is displayed on an interactive interface of the receiving terminal. Since both the signature result and the identity certificate are verified, the receiving user can thereby determine that the sender identity of the 5G message has not been spoofed.
When any one of the signature result and the identity certificate fails to pass the verification, the receiving party user can be reminded according to a preset control strategy, for example, 5G information is automatically put into a deleted mailbox, or after the receiving party user is prompted that the verification fails, the 5G information is still normally put into an inbox.
In one embodiment, the sender may not sign the recipient phone number in a particular scenario, provided that the default 5G message channel ensures that no confusion will occur at the recipient terminal. For example: when the sender needs to send the same 5G message to multiple receivers, the sender can sign only the 5G message, the sender number and the sending time, but not the receiver phone number, so that the resource consumption of the sender in the signature result generation process is reduced.
The sender may send only a normal 5G message or may send a 5G message with an identity certificate and a signature result. The sender user can identify whether a 5G message has a corresponding identity certificate and a signature result through a specific field, so that after the receiver receives the 5G message, the receiver can autonomously confirm whether the signature result and the downloading and verifying process of the identity certificate are needed, and the resource consumption of the receiver terminal and the downloading or verifying of the identity certificate and the signature result is reduced.
The signature operation is carried out on the 5G message at the sender terminal, and the sender terminal carries out the signature processing on the 5G message based on the secret key stored in the sender terminal, so that the identity of the sender is further ensured not to be impersonated, the reliability of a signature result is improved, and the 5G message is processed in a mode of carrying out the signature verification operation at the receiver terminal, so that the tamper-proof processing and the signature processing of the 5G message are not based on an operation service provider of the 5G message, thereby ensuring the signature verification protection of the message from the sender to the receiver, namely reaching an end-to-end level, and if the message is modified by an unauthorized party in the transmission process, the receiver terminal can judge that the modification is illegal tampering. The transmission of trusted authentication is provided for 5G messages at the user side level.
In one embodiment, the generating the signature result corresponding to the 5G message based on the key corresponding to the identity certificate of the sender user pre-stored in the sender terminal includes:
and reading a private key corresponding to the identity certificate of the sender user, and signing the 5G message, the number of the sender terminal, the number of the receiver terminal and the sending time of the 5G message by using the private key to obtain the signature result.
The private key corresponding to the identity certificate of the sender user is read, the private key is utilized to sign the 5G message, the number of the sender terminal, the number of the receiver terminal and the sending time of the 5G message, a signature result can be obtained, and the private key used for signature exists in the sender terminal, so that the reliability of signature can be further improved.
In one embodiment, the transmitting the 5G message, the signature result, and the identity certificate to a recipient terminal includes:
transmitting the 5G message, the signature result and the identity certificate to a receiver terminal through a first channel based on the number of the receiver terminal;
or transmitting the 5G message and the signature result to the receiver terminal through a first channel based on the number of the receiver terminal, and transmitting the identity certificate to the receiver terminal through a second channel;
or transmitting the 5G message to the receiver terminal through a first channel based on the number of the receiver terminal, and transmitting the signature result and the identity certificate to the receiver terminal through a second channel.
The first channel may refer to a 5G short message channel, i.e. a communication channel of a telephone operator. The second channel may be an internet channel or a cloud service mode, and when the identity certificate or the signature result is transmitted through the second channel, the receiver terminal needs to apply for downloading the identity certificate or the signature result from the corresponding server.
Referring to fig. 2, a flowchart of another preferred embodiment of the method for transmitting a 5G message according to the present application is shown, which may be performed by a receiving terminal, which may be implemented in software and/or hardware. The transmission method of the 5G message comprises the following steps:
step S210: acquiring an identity certificate of a sender user, a 5G message and a signature result corresponding to the 5G message, which are transmitted by a sender terminal;
step S220: verifying whether related fields in the signature result are valid or not, and verifying whether the identity certificate is valid or not;
step S230: and feeding back the 5G message to a receiver user when the relevant field in the signature result is verified to be valid and the identity certificate is verified to be valid.
In this embodiment, the identity certificate and the signature result acquired by the receiver terminal may be transmitted to the receiver terminal by the sender terminal according to the communication channel of the telephone operator, or the sender terminal may upload the identity certificate and the signature result to the server through a cloud service mode, and the receiver terminal downloads the identity certificate and the signature result from the server, thereby acquiring the identity certificate and the signature result.
After the receiving terminal acquires the identity certificate of the sending user, the 5G message and the signature result corresponding to the 5G message, verifying whether relevant fields in the signature result are valid or not through a public key corresponding to the identity certificate, and verifying whether the identity certificate is valid or not, specifically:
the receiving terminal obtains a Hash value of the identity certificate by utilizing a Hash algorithm pre-agreed by the sending terminal and the receiving terminal, marks the Hash value as Hash1, obtains a public key corresponding to the identity certificate, decrypts the identity certificate by utilizing the public key to obtain Hash2, compares whether the Hash1 and the Hash2 are consistent, and if so, indicates that the identity certificate is a trusted certificate (namely, the identity certificate is valid), otherwise, considers that the identity certificate is not trusted.
And verifying whether the relevant fields in the signature result are valid or not is approximately the same as the method for verifying whether the identity certificate is valid or not, namely, the hash value obtained by verifying the correlation of the signature result through the public key of the identity certificate is compared with the hash value of the signature result obtained by a pre-agreed hash algorithm, when the hash values are consistent, the signature result is valid, and otherwise, the signature result is invalid.
And when the relevant field in the verification signature result is valid and the verification identity certificate is valid, feeding back the 5G message to the user of the receiving party, for example, putting the 5G message into an inbox or displaying the content of the 5G message on an interactive interface of the terminal of the receiving party. Since both the signature result and the identity certificate are verified, the receiving user can thereby determine that the sender identity of the 5G message has not been spoofed. When any one of the signature result and the identity certificate fails to pass verification, it is indicated that the 5G message sent by the sender may be tampered, and at this time, the receiver user may be reminded according to a preset control policy, for example, the 5G message is automatically put into a deleted mailbox, or after the receiver user is prompted that the verification fails, the 5G message is still normally put into an inbox.
Further, the verifying whether the relevant field in the signature result is valid includes:
acquiring a public key corresponding to the identity certificate, and verifying a relevant field of the signature result by using the public key;
when all the fields of the related fields are verified to be successful, the related fields of the signature result are valid;
when any one of the relevant fields fails to be verified, the relevant field of the signature result is invalid.
Because the signature result includes the signature of the key pair 5G message, the sender telephone number, the receiver telephone number, the timestamp of the message transmission, and other information of the sender user, when the signature of the 5G message, the sender telephone number, the receiver telephone number, the timestamp of the message transmission, and other information passes verification, the signature result is considered to pass verification (namely the signature result is valid). When any one of the fields of the 5G message, the sender telephone number, the receiver telephone number and the timestamp of the message transmission fails to verify, the signature result is considered to be not verified (namely, the signature result is invalid).
In one embodiment, the method further comprises:
and when the relevant fields in the signature result are verified to be valid and the identity certificate is verified to pass, displaying a verification result on an interactive interface of the receiver terminal.
After the signature result and the identity certificate pass verification, the verification result may be displayed on the receiver terminal, for example, "sender identity verification pass" is displayed on the interactive interface of the receiver terminal.
