It can be understood that the executing body of the 5G message storage and verification method provided by the embodiment of the present invention includes, but is not limited to, the message sender apparatus 1.

According to one aspect of the invention, the embodiment discloses a 5G message storage and verification method. As shown in fig. 2, in this embodiment, the method includes:

S300: and transmitting the encrypted message to a message receiver through a 5G link so that the message receiver decrypts the encrypted message, verifies the decrypted message body, and deletes the 5G message if the verification fails.

In a preferred embodiment, as shown in fig. 3, the determining, by the S100, a message type of a received 5G message sent by a message sender, and performing partition storage on the 5G message according to the message type specifically includes:

s110: and determining the message type and the importance level of the 5G message according to the message type suffix.

S120: and packaging the 5G message by a Bayesian algorithm according to the message type and the importance level, and then storing the packaged 5G message in a partitioned manner.

Specifically, in the preferred embodiment, the message type of the 5G message may be determined from a message type suffix of the 5G message. The 5G message is a rich media, and thus, the message type of the 5G message may include at least one of a type of text, a picture, audio, video, and a location. As known to those skilled in the art, for different message types, different message type suffixes are correspondingly set in the 5G message, and the message type of the 5G message can be determined according to the preset correspondence between the message type and the message type suffix and the message type of the received 5G message.

In the preferred embodiment, the importance of the 5G messages of different message types is different, so that different importance levels can be set for different message types in advance, the 5G messages are stored according to the importance levels of the 5G messages, the hierarchical storage of the 5G messages can be realized, the storage mode of the 5G messages is optimized, and the 5G messages with low importance levels can be compressed, so that the storage pressure of the whole 5G message storage system is reduced, and the data amount required to be stored is reduced. Specifically, a Bayesian algorithm can be adopted according to the message types and the importance levels to perform encapsulation and then store the encapsulated message in a partitioned manner, so that the classified management of the 5G messages of different message types can be realized.

It should be noted that, those skilled in the art may implement flexible dynamic expansion and uniform storage of the bottom storage node of the 5G message by using an extended hash encoding method according to actual requirements, which is not described herein again.

In a preferred embodiment, as shown in fig. 4, the encrypting the 5G message and the message body by S200 to obtain the encrypted message may specifically include:

s210: a session key is formed and the 5G message is encrypted.

S220: and encrypting a message body corresponding to the 5G message through the session key, wherein the message body comprises a message subject, a user uniform identifier, operation time and a message signature.

Specifically, in the preferred embodiment, in order to ensure the security of 5G message transmission and prevent the 5G message from being tampered, encryption, decryption and verification processes need to be performed on both the message sender and the message receiver to ensure the security of the message sender, the message receiver and the message during transmission. Thus, in the preferred embodiment, in order to ensure the security of 5G message transmission and prevent the 5G message from being tampered, at the message sender, a KDF may be used to generate a session key SK and encrypt the 5G message with the session key SK. More preferably, in the financial field, since the 5G message may relate to sensitive data related to finance, a counter triggering mode may be adopted to generate the session key according to the limited session key encryption times. The highest level of security may be applied to sensitive data, setting the session key to one complete data transmission and one change.

The message body is obtained from the 5G message and needs to be sent to the message recipient together with the 5G message. Therefore, a message body corresponding to the 5G message needs to be encrypted through the session key, where the message body includes a message subject T, a user uniform identifier UUID, an operation time T, and a message signature sig. In the preferred embodiment, the UUID also serves as both a public key for verifying the signature information and an identification of the importance level of the 5G message. The message encryption adopts AES symmetric encryption, and the encryption key is a pre-generated session key SK. In other embodiments, the 5G message and the message body may be encrypted by other keys, which is not limited by the present invention.

In a preferred embodiment, as shown in fig. 5, the method further includes a step S000 of pre-forming the user unified identifier:

s010: device information of a mobile device is acquired and biometric information of a user is acquired via the mobile device.

S020: and transmitting the biological characteristic information to a mobile equipment server so that the mobile equipment server matches the biological characteristic information, and receiving pre-stored equipment information and pre-stored user information returned by the mobile equipment server if matching is successful.

S030: acquiring user information from an SIM card of mobile equipment, verifying the equipment information and the user information of the mobile equipment according to the pre-stored equipment information and the pre-stored user information, and if the verification is passed, forming a user unified identifier according to the biological characteristic information and the user information.

It can be understood that the formation of the UUID needs to interact with the mobile device server and the mobile device, and the function of the UUID is to integrate the user device information and the user information. The biological characteristic information of the user can be collected in advance and stored in the mobile equipment server, and the equipment information and the user information of the mobile equipment of the user can be collected at the same time to form preset equipment information and prestored user information which are stored in the mobile equipment server and are associated with the biological characteristic information of the user, so that the subsequent association matching of the biological characteristic information transmitted by a message sender is facilitated. The biometric information may be user unique biometric information such as a user fingerprint, and is used to mark the user identity.

Specifically, the user fingerprint can be acquired through the mobile device serving as the message sender, uploaded to the mobile device server, and returned to the device id (device information) and the user id (user information) if the verification of the user fingerprint and the pre-stored fingerprint information of the device is successful. The subscriber information may then be obtained from the mobile device SIM card information and double checked against the received subscriber id transmitted by the server. If the verification is passed, the equipment information and the user information can be packaged to form the UUID. In other embodiments, the user information and the device information can be directly acquired without passing or failing to acquire the fingerprint, but the validity rating of the UUID is lowered because the fingerprint is not checked again, and subsequent processing and alarming of the message are affected.

In a preferred embodiment, the message receiver is further configured to obtain current status information of the message receiver if the check is passed. And matching and judging the current state information with the pre-acquired historical state information of the message receiver, and deleting the 5G message if the judgment is failed.

Specifically, in order to ensure the security of the operating environment of the message receiver, the state of the message receiver needs to be checked after the encrypted message is received, and if the operating state of the message receiver is abnormal, the decrypted 5G message is deleted, so that the problems of leakage and the like of the 5G message are prevented. Specifically, before the encrypted message is sent to the message receiver through the 5G link, the state information of the message receiver may be recorded to obtain and store the historical state information, and this operation may be implemented by the message receiver, or may be implemented by the message sender or other devices, which is not limited in this invention. And after the message receiver receives the encrypted message sent by the message sender, acquiring the real-time state information of the message receiver, determining whether the running states of the message receiver are consistent or not according to the historical state information and the real-time state information, and if not, deleting the 5G message in time.

In a preferred embodiment, the message receiver further sends a resending request to the message sender after deleting the 5G message, so that the message sender resends the encrypted message, receives and decrypts the encrypted message sent again by the message sender, and verifies a message body obtained by decryption until the received encrypted message passes verification.

Specifically, when the content of the encrypted message or the operating state of the message receiver is abnormal, the resending request can be resent to the message sender, and the message sender can resend the encrypted message to the message receiver through the 5G link after receiving the resending request, so that the message receiver can perform verification again. If the verification still fails, the steps can be repeated until the verification passes.

The verification of the decrypted message body may include performing message content authentication, source and sink authentication of the message, and message operation time authentication on the message body. The safety and the integrity of the received encrypted message are ensured through various authentication modes.

In a preferred embodiment, the authenticating the message content, the authenticating the source and the sink of the message, and the authenticating the message operation time of the message body specifically include: obtaining a message theme, a user unified identifier, operation time and a message signature according to the message body; determining a consistency parameter of the message body, an integrity parameter of the user unified identifier and an importance level of the 5G message; and obtaining a message authentication value according to the consistency parameter, the integrity parameter, the importance level and the operation time, and if the message authentication value is lower than a preset threshold value, the verification is failed.

Specifically, the decrypted message body is verified, a consistency parameter a of the message body is determined according to the content of the message body, an integrity parameter u of the user uniform identifier is determined according to the user uniform identifier, an importance level E of the 5G message is determined according to the user uniform identifier, and a message authentication value is obtained according to the received consistency parameter a, the integrity parameter u, the importance level E and the operation time t of the message body according to an authentication value calculation rule. Further, a threshold value can be preset, and when the message authentication value is lower than the preset threshold value, it indicates that the message body is missing or wrong, and the verification fails. It should be noted that, those skilled in the art may determine the authentication value calculation rule and the preset threshold according to actual requirements, and the present invention is not limited thereto.

In a preferred embodiment, before the encrypted message is not transmitted to the message receiver, the message sender can withdraw the encrypted message according to preset conditions and correct the problems of sending errors and the like.

In a preferred embodiment, the 5G message storage and verification method may further include: the method comprises the steps of obtaining information of a message sender, information of a message receiver and 5G messages at regular time, monitoring the running states of the message sender and the message receiver according to the information of the message sender and the information of the message receiver, monitoring and counting the information of the message sender, the information of the message receiver and the 5G messages, and giving an alarm to a user when the information of the message sender, the information of the message receiver and the 5G messages are abnormal. The abnormality includes the abnormal operation state of the message sender and the message receiver, and also includes the abnormal conditions of the content and the sending frequency of the 5G message.

The highest level of security may be applied to sensitive data, setting the session key to one complete data transmission and one change. Go to Step 4.

Step 4: authenticating and encrypting a message signature, wherein the message body is { T, UUID, T, sig }, and T is a theme corresponding to the published data; the UUID is a unified identification of the user information, and the device can acquire the UUID through the fingerprint information prestored in the equipment and the information of the built-in SIM card. The UUID also serves as a public key of signature information of the verification device and a key parameter of rating; t is the timestamp and sig is the message signature. The message encryption adopts AES symmetric encryption, and the encryption key is a session key SK pre-generated by a publisher. Go to Step 5.

Step 8: and the message receiver decrypts the message main body and performs AES decryption on the encrypted message main body by using the decrypted SK to obtain the message main body. Go to Step 9.

Step 9: and judging the decrypted message body, namely judging the consistency a of the timestamp t and the message body, obtaining an authentication value according to the message importance E classified by the UUID of the message body and the data integrity u of the UUID of the user, and if the authentication value is lower than a preset threshold value W, alarming, and informing a message sender of message retransmission, and discarding the message, namely deleting the 5G message. Go to Step 10.

Step 10: if the state of the receiver before sending the message is recorded by the message monitoring module, whether the state of the message receiver is consistent with the previous state is judged, if not, the message processing module informs the sender to resend the message, and the message is discarded. Go to Step 11.

Step 11: if the encrypted message is consistent with the encrypted message, the encrypted message is successfully received by the message receiver, and the information communication is ended. Go to Step 12.
