All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a terminal data uplink method executed by a SIM card according to an embodiment of the present invention, where the method includes:

s101, receiving a service data uplink request, wherein the service data uplink request is a request sent to the SIM card by a terminal after responding to the first operation;

the terminals are mostly control execution devices or sensing units in the field of internet of things, are responsible for an initiator of a business data processing flow in the whole system, and provide original data service for a target link object. The terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device.

The first operation is a business operation performed by a user or an operator on the terminal, for example, a transaction operation is performed. At this time, in the case that the first operation is that the user or the operator completes a transaction on the terminal, the terminal responds to the first operation and sends the content of the transaction operation to the SIM card by means of a service data uplink request.

The SIM, i.e. the subscriber identity module, is essentially a UICC card (universal integrated circuit card). The main function of the system is to provide identification information and stored data when the mobile terminal device communicates with the network, and to complete the whole process of identification authentication and information interaction under the safe condition, i.e. under the condition that the Personal Identification Number (PIN) and the authentication key are correct.

The SIM card is a special application of a security chip, and generally requires to have the protection capability of hardware attack, the security level requirement reaches EAL4+ (the evaluation level of the information technology security evaluation criterion) and is divided into 7 levels, and EAL4+ is the security level of EAL4 and above), so that the security of data stored in the SIM card can be effectively guaranteed, and malicious tampering can be prevented.

S102, responding to the service data uplink request, and sending a first command to the terminal based on a data transmission protocol, wherein the first command is used for establishing a communication connection relationship among the SIM card, the terminal and a block chain platform.

The first command is a command which is realized by depending on the active command function of the SIM card and is sent to the terminal based on a data transmission protocol to request the cellular communication module to establish basic network communication service with the block chain platform. For example, after receiving a service data uplink request, the SIM card responds to the service data uplink request and sends a first command to the terminal by using an active command function based on a data transmission protocol, so that the terminal can establish a communication connection relationship with the blockchain platform through the first command.

The cellular communication module provides the connection capability of a cellular network for the terminal, realizes basic data communication service, receives an instruction request of a control terminal, initiates service processes such as service data safety processing and the like, and sends a data message to a target link object.

The block chain is a public distributed shared database, and has the characteristics of decentralization, non-tamper property, auditability, anonymity, independence and the like. The block chain utilizes technologies such as a consensus mechanism, an intelligent contract and asymmetric encryption, can realize the falsification prevention, the forgery prevention and the traceability of information in the processes of information storage, sharing and the like, and comprises a data layer, a network layer, a consensus layer, an intelligent contract layer and an application layer framework.

In the embodiment, the SIM card is used for sending the first command to the terminal to establish the communication connection relation among the terminal, the SIM card and the block chain platform, so that the terminal equipment is prevented from directly establishing the communication connection relation with the block chain platform, and the risk of leakage of the communication information of the terminal is reduced.

Specifically, a first command is sent to a cellular communication module of the terminal through the SIM card, and the cellular communication module establishes a communication connection relation with the block chain platform after receiving the first command, so that the network access and authentication functions of a cellular network are realized, the legal access of the terminal to a cellular base station is guaranteed, and reliable internet communication service is provided.

As an alternative implementation manner, referring to fig. 2, fig. 2 is a second flowchart of a terminal data uplink method executed by a SIM card according to an embodiment of the present invention, where after the first command is sent to the terminal based on a data transmission protocol, the method includes:

s103, calculating and format converting the business data uplink request based on a preset block chain application to obtain a safety message;

the blockchain application is a module which is arranged in the SIM card and provides encryption service, and the risk of hardware attack and the risk of leakage in the encryption operation process are reduced through a high-security hardware environment and a high-security storage operation environment based on the SIM card. Therefore, encryption service can be provided for blockchain application by depending on the security environment of the SIM card, and the establishment of a secure and credible communication connection relation is realized by adopting a service based on the encryption service, so that the confidentiality and the legality in the data transmission process are ensured.

And S104, based on the data transmission protocol, sending the safety message to the block chain platform according to the communication connection relation.

In the embodiment, by using the blockchain application and using the high-security hardware environment and the high-security storage and operation environment of the SIM card, the risk of hardware attack and the risk of data leakage can be effectively reduced, so that the terminal and the blockchain platform can establish a secure and reliable communication connection relationship.

As an alternative embodiment, the blockchain application includes a security algorithm, a random number, an anti-replay factor counter, and a data processing algorithm;

the calculating and format converting the service data uplink request based on the preset block chain application to obtain a safety message comprises:

based on the random number and the anti-replay factor counter, performing data format conversion on the service data uplink request by using the data processing algorithm to obtain first intermediate data;

processing the first intermediate data based on the security algorithm to obtain second intermediate data;

and based on the random number, the anti-replay factor counter processes the second intermediate data by using the data processing algorithm to obtain the safety message.

In the embodiment, the random number and the anti-replay factor counter are used, so that the block chain platform can identify replay attack, and illegal equipment is prevented from cheating the system to acquire data.

After the block chain platform receives the security messages sent by the multiple SIM cards, for example, after the block chain platform receives the first message and the second message with the same content, the block chain platform obtains the random number and the anti-replay factor counter by parsing the first message and the second message, and when the random number and the anti-replay factor counter of the first message are the same as those of the second message, the first message and the second message are determined to be the same message, and the terminal sending the second message cannot be determined to be a legal device, and does not perform other processing or storage on the second message.

Wherein the random number and the anti-replay factor counter are generated for the SIM card itself. The SIM card can enhance the security intensity of data by processing and format conversion twice on the service data uplink request by using a hash function based on a random number and a replay prevention factor counter. Similarly, the block chain platform receiving the security message needs to perform two processing and format conversion on the security message to obtain the random number and the anti-replay factor counter, so that data content is prevented from being leaked after the terminal is accessed to other block chain platforms.

As an alternative embodiment, the security algorithm includes key agreement, key dispersion, encryption algorithm and signature algorithm, and the second intermediate data includes encryption data, signature data and anti-replay factor;

the processing the first intermediate data based on the security algorithm to obtain second intermediate data comprises:

processing the first intermediate data based on the key agreement, the key dispersion and the signature algorithm to obtain the signature data;

processing the first intermediate data based on the encryption algorithm to obtain the encrypted data;

the anti-replay factor is obtained based on the random number and an anti-replay factor counter.

In the embodiment, by depending on the security key storage and operation environment of the SIM card, the security and credibility of the whole service data processing and reporting process can be ensured, and an attacker is prevented from sniffing and counterfeiting; the protected information can be effectively prevented from being stolen after the security message is leaked through the encrypted data.

The signature data is a signature key, the signature key is a section of digital string which is generated by the SIM card and cannot be forged, and the authenticity of the transmitted information can be proved. The integrity of the signature key is easy to verify, so that the safety and the reliability of the service data can be guaranteed through the signature key.

The signature Key calculation may support, but is not limited to, an international or national cryptographic algorithm, a symmetric or asymmetric Key, a PKI (Public Key Infrastructure) certificate service, and the like, and the specifically used signature Key may be negotiated and selected with the blockchain platform. The signature key calculation is carried out in the secure hardware environment and the storage operation environment of the SIM card, so that the security of the signature key stored in the SIM card and the security of the service data processing flow operated in the SIM card can be effectively guaranteed.

Referring to fig. 3, fig. 3 is a flowchart of a terminal data uplink method executed by a terminal according to an embodiment of the present invention, where the method includes:

s201, sending a service data uplink request to an SIM card, wherein the service data uplink request is a request sent to the SIM card by the terminal in response to a received first operation;

s202, receiving a first command, wherein the first command is sent to the terminal by the SIM card in response to the service data uplink request based on a data transmission protocol, and the first command is used for establishing a communication connection relationship among the SIM card, the terminal and a block chain platform;

s203, establishing a communication connection relation among the SIM card, the terminal and the block chain platform based on a data transmission protocol according to the first command.

In the embodiment, the terminal establishes the communication connection relationship among the SIM card, the terminal and the block chain platform through the first command sent by the SIM card, so that the terminal is prevented from directly establishing the communication connection relationship with the block chain platform, the terminal is prevented from being attacked and accessed to an illegal block chain platform, and the risk of information leakage is reduced.

The data transmission protocol of the terminal, the data transmission protocol of the SIM card and the data transmission protocol of the block chain platform are consistent, and the communication connection relation among the SIM card, the terminal and the block chain platform can be established based on a first command sent by the SIM card.

As an optional implementation manner, the data transmission protocol is a Bearer Independent Protocol (BIP), and the establishing, according to the first command and based on the data transmission protocol, a communication connection relationship between the terminal and the block chain platform includes:

analyzing the first command to obtain a node address of the block chain platform;

sending a second command to the node address, wherein the second command is used for requesting the blockchain platform to establish a communication connection relationship with the terminal;

and establishing a communication connection relation among the SIM card, the terminal and the block chain platform based on the independent bearer protocol and a protocol adaptation system preset by the block chain platform.

In this embodiment, since the SIM card is required to actively send a command for establishing a communication connection relationship, a BIP technology is adopted, wherein the BIP technology increases the new active operation capability of the SIM card based on the original passive operation mode of the SIM card, that is, allows applications and services in the SIM card to actively interact with the cellular terminal.

In the conventional technology, an asymmetric master-slave relationship exists between the summary terminal and the SIM card, that is, the SIM card can only passively receive and execute the instruction of the mobile phone, and the mobile phone is in an absolute active control position. Any action can only be initiated by the handset and responded to by the SIM card. And the use of BIP technology can allow the SIM card to perform data Transmission between a remote server and a TCP/IP (Transmission Control Protocol/Internet Protocol).

Among them, the BIP technology supports five active commands of opening a connection (OPEN CHANNEL), closing a connection (CLOSE CHANNEL), acquiring a connection state (GET CHANNEL STATUS), receiving DATA (RECEIVE DATA), and transmitting DATA (SEND DATA). In this embodiment, the first command sent by the SIM card to the terminal belongs to a connection opening command, and the terminal can establish a communication connection relationship between the terminal and the blockchain platform based on the BIP after receiving the connection opening command. After the communication connection relationship is established between the terminal and the block chain platform, the SIM card can send a safety message to the block chain platform through the communication connection relationship.

And after the terminal sends the second command to the block chain platform, the block chain platform adapts the BIP technology according to the protocol adaptation system, and then establishes a communication connection relation between the terminal and the block chain platform according to the second command.

In addition, the BIP technology can improve the transmission efficiency and stability between the terminal and the block chain platform, and is beneficial to realizing the transmission of high-speed mobile data service, so that the transmission of various service data becomes easier and faster.

In addition, aiming at different terminals, the terminal can be quickly accessed into the block chain link point platform by replacing the SIM card supporting the block chain application, the butt joint and application complexity of the block chain application control terminal service data uplink and the transformation cost and research and development investment of terminal scheme business and modules are effectively reduced, the software and hardware of the control terminal can be modified to zero or extremely few, and the complete service data uplink process is realized.

The Protocol adaptation system of the block chain platform provides a lightweight underlying communication data Protocol-based service for uplink security service data, including but not limited to TCP (Transmission Control Protocol), UDP (User Datagram Protocol), coAP (Constrained Application Protocol), and the like. In this embodiment, the communication connection relationship between the terminal and the blockchain platform is realized through the BIP technology, the service data secure uplink process is completed, and the direct establishment of the terminal and the docking between blockchain platforms are avoided, so that the risk of information leakage is reduced.

Compared with the prior art, the protocol adaptation system is converted into a complex HTTP protocol service to communicate with the service platform, so that the data flow, the system response delay, the system power consumption, the hardware resource consumption and the like in the whole process are reduced

determining whether the secure message belongs to a duplicate message based on the nonce and the anti-replay factor counter;

and processing and storing the decrypted data based on a preset data processing and storing system under the condition that the safety message does not belong to the repeated message.

In the embodiment, replay attack can be prevented through the random number and the replay-resistant factor counter, and the decrypted data which is not attacked by replay is processed and stored through the data processing and storing system, so that the risk of information leakage is reduced.
