Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover non-exclusive inclusions, e.g., a process or an apparatus that comprises a list of steps is not necessarily limited to those structures or steps expressly listed but may include other steps or structures not expressly listed or inherent to such process or apparatus.
Fig. 1 is a flowchart of a registration method of a 5G user terminal according to an embodiment of the present application, and as shown in fig. 1, the method includes:
The blockchain referred to in this embodiment is a blockchain maintained by an operator, the temporary identity registration server accesses the blockchain and records and maintains the latest public keys of all operators in the blockchain, the 5G UE or other terminal devices may be accessed into the blockchain as nodes of the blockchain, and the blockchain may be used to record registration information of each node in the blockchain and transaction information between each node. The 5G UE referred to in this embodiment may not have an access function of a complete block chain, as long as the capability of verifying and analyzing the block on the block chain and retrieving the block record under a certain specified condition is available.
For example, fig. 2 is a schematic structural diagram of a communication system according to an embodiment of the present invention, where in the system shown in fig. 2, a device UE may be understood as a 5G user terminal device referred to in this embodiment, a 5G core network (5G core network, 5GC) of an operator accounts a public key of the operator in a block chain, and a temporary identity registration server accesses the block chain and records and maintains the public key of each operator. In the registration process, the 5G UE first generates a public key and a private key (for convenience of distinguishing a first public key and a first private key), which correspond to a temporary identity, and then sends a registration application carrying the first public key to an Access and mobility Management Function (AMF) or a Session Management Function (SMF) in the 5GC through the 5G base station gNB, the AMF or the SMF notifies a User Plane network Function (User Plane Function, UPF) to transfer the registration application to the temporary identity registration server, and after receiving the registration application, the temporary identity registration server signs block information of all blocks in a block chain by using its own private key, and returns the signed information to the 5G UE. The block information of the block includes, but is not limited to: the hash value of the block, the hash value of the previous block, and the content information of the block.
And 102, the 5G user terminal equipment receives the block information of the block chain returned by the temporary identity registration server according to the registration application, and performs hash value verification on the block chain and the blocks in the block chain according to the block information.
After receiving the block information fed back by the temporary identity registration server, the 5G UE firstly verifies the private key signature in the block information based on the pre-obtained public key of the temporary identity registration server, if the verification is passed, further calculates the hash value of each block based on the block information of each block fed back by the temporary identity registration server, and comparing the hash value of each block obtained by calculation with the hash value of each block carried in the block information fed back by the temporary identity registration server, verifying whether the hash value of each block obtained by calculation is consistent with the hash value of each block recorded in the block information, and verifying whether the hash value of each block is less than the predetermined difficulty value and whether the hash value of the previous block is recorded in each block, if the above-mentioned verification is passed, and searching and obtaining the public key of the target operator from the block information fed back by the temporary identity registration server according to the identifier of the target operator.
Optionally, in a feasible manner, the 5G UE may traverse the block information of each block returned by the temporary identity registration server one by one to obtain the public key of the target operator.
Optionally, in another feasible manner, in order to improve the efficiency of searching the target operator public key by the 5G UE, pointer information of the target block may be further added to the block information fed back by the temporary identity registration server, where the target block is a block in which the target operator public key is recorded, and the pointer information of the target block is used to notify the 5G UE which block is the target block, so that the 5G UE can quickly and accurately lock the target block according to the pointer information of the target block, and the efficiency of acquiring the target operator public key is improved.
And step 104, the 5G user terminal equipment encrypts a second public key corresponding to the permanent identity of the user terminal equipment by using the public key of the target operator and the first public key according to a preset encryption algorithm, and sends encrypted data obtained by encryption to the temporary identity registration server for identity registration.
The preset encryption algorithm referred to in this embodiment is an encryption algorithm shared by the 5G UE and the temporary identity registration server. In order to ensure that the second public key of the permanent identity sent by the 5G UE is not monitored or replaced, the 5G UE needs to encrypt the second public key by adopting the public key of the target operator or the public key of the target operator and the first public key before sending the second public key to the temporary identity registration server according to a preset encryption algorithm, the encrypted data is sent to the temporary identity registration server after being signed by adopting the first private key of the 5G UE, after the temporary identity registration server receives the encrypted data, the signature of the private key of the encrypted data is firstly verified by adopting the first public key of the 5G UE, and if the encrypted data passes the verification, the encrypted data is decrypted based on the preset encryption algorithm to obtain the second public key of the 5G UE, so that the 5G UE is registered based on the second public key.
Of course, it should be understood by those skilled in the art that although the above embodiment only describes a method for encrypting the second public key of the 5G UE, in an actual scenario, not only the second public key but also other registration information of the 5gu may be encrypted, for example, in a possible scenario, an International Mobile Equipment Identity (IMEI) number of the 5G UE may also be encrypted, or in yet another possible scenario, a hash value of the second public key and/or the IMEI number may also be encrypted.
In this embodiment, the 5G user terminal device carries the first public key corresponding to the pre-generated temporary identity in the registration application and sends the first public key to the temporary identity registration server in the block chain, so that the temporary identity registration server returns the block information of the block chain according to the registration application, and the 5G user terminal device performs hash value verification on the block chain and the block in the block chain according to the block information returned by the temporary identity registration server, and searches and obtains the public key of the target operator from the block information returned by the temporary identity registration server according to the identifier of the target operator when the verification is passed, because the embodiment of the present invention does not directly send the public key of the target operator to the 5G user terminal device as in the prior art, but sends the block information of the block chain to the 5G user terminal device, because the difficulty of forging the block chain block is much greater than the difficulty of forging the public key of the operator, therefore, the issuing security and confidentiality of the public key of the target operator can be improved, further, after the 5G user terminal equipment obtains the public key of the target operator, the public key of the target operator and the first public key corresponding to the temporary identity of the 5G user terminal equipment are adopted to encrypt the second public key corresponding to the permanent identity of the 5G user terminal equipment through a preset encryption algorithm, the encrypted data are sent to the temporary identity registration server to perform identity registration, the security and confidentiality of the permanent identity public key sent by the 5G user terminal equipment to the temporary identity registration server can be improved, and the security and confidentiality of the whole registration process are further protected.
Fig. 3 is a flowchart of a registration method of a 5G user terminal according to an embodiment of the present application, and as shown in fig. 3, on the basis of the foregoing embodiment, the method includes:
In this embodiment, the 5G UE searches for 5G signal strength information around itself, and determines a target operator according to the signal strength information of each operator around itself. And the identifier of the target operator and the first public key of the target operator are carried in the registration application and are sent to the temporary identity registration server.
For example, after receiving the block information of the first block, the hash value of the first block may be calculated, and whether the calculated hash value is consistent with the hash value of the first block fed back by the temporary identity registration server, whether the calculated hash value is smaller than the preset difficulty value, and whether the first block includes the hash value of the previous block may be determined, if all the results of the above determination are yes, the verification is passed, otherwise, the verification fails. Of course, this is only an example and is not the only limitation to the verification method of the present application. For example, in some scenarios, considering that the more the tile information fed back to the 5G UE by the temporary identity registration server, the greater the difficulty of forging the tile information, on the basis of returning the tile information of the first tile to the 5G UE, the tile information of N tiles before the first tile and M tiles after the first tile may also be returned to the 5G UE, so that the 5G UE performs hash value verification based on the received tile information of all tiles. The values of N and M can be set according to requirements, and the larger the value of N and/or M is, the higher the security and confidentiality of the registered data are.
And step 304, the 5G user terminal equipment encrypts a second public key corresponding to the permanent identity of the user terminal equipment by using the public key of the target operator and the first public key according to a preset encryption algorithm, and sends encrypted data obtained by encryption to the temporary identity registration server for identity registration.
In this embodiment, the 5G user terminal device carries the first public key corresponding to the pre-generated temporary identity in the registration application and sends the first public key to the temporary identity registration server in the block chain, so that the temporary identity registration server returns the block information of the block chain according to the registration application, and the 5G user terminal device performs hash value verification on the block chain and the block in the block chain according to the block information returned by the temporary identity registration server, and searches and obtains the public key of the target operator from the block information returned by the temporary identity registration server according to the identifier of the target operator when the verification is passed, because the embodiment of the present invention does not directly send the public key of the target operator to the 5G user terminal device as in the prior art, but sends the block information of the block chain to the 5G user terminal device, because the difficulty of forging the block chain block is much greater than the difficulty of forging the public key of the operator, therefore, the issuing security and confidentiality of the public key of the target operator can be improved, further, after the 5G user terminal equipment obtains the public key of the target operator, the public key of the target operator and the first public key corresponding to the temporary identity of the 5G user terminal equipment are adopted to encrypt the second public key corresponding to the permanent identity of the 5G user terminal equipment through a preset encryption algorithm, the encrypted data are sent to the temporary identity registration server to perform identity registration, the security and confidentiality of the permanent identity public key sent by the 5G user terminal equipment to the temporary identity registration server can be improved, and the security and confidentiality of the whole registration process are further protected.
