And uploading the computation force intensive operator to the cloud server through the 5G channel, and completing computation on the cloud server by the uploaded computation force intensive operator.
To facilitate understanding of the details of this embodiment, the operational symbols involved and their description are shown in table 1 below:
TABLE 1
In this embodiment, uploading the computationally intensive operator to a cloud server includes:
generating a computation request Rin containing the computationally intensive operator;
encrypting and packaging the calculation request to form encrypted data Hin;
and signing the encrypted data and the calculation request, and then sending the encrypted data and the calculation request to the cloud server.
Wherein, in the present embodiment, the computation request includes the computationally intensive operator, a read set of the computationally intensive operator, a state of the computationally intensive operator.
Specifically, the mobile terminal pre-processes the instruction, splits the instruction into independent operators, calculates rin=cin (R, op, si), hin=hash (Rin), sig=sign (Rin, hin), wherein Op is a computationally intensive operator, and Rin, hin is uploaded to the cloud server.
The mobile terminal uploads the computationally intensive operator Op, the state Si, and the read set R to a cloud server (specifically, a processor chip TEE of the cloud) through a 5G network.
In step S210, the cloud server receives a calculation request of the computationally intensive operator from the mobile terminal.
Step S220, calculating the computationally intensive operator according to the calculation request, obtaining a cloud end calculation result, and feeding back the cloud end calculation result to the mobile terminal.
In this embodiment, the cloud server stores the received calculation request in the trusted execution environment TEE, and calculates the computationally intensive operator through an algorithm built in the trusted execution environment TEE to generate the cloud calculation result.
The trusted execution environment (Trusted Execution Environment, TEE) can isolate a trusted execution environment from an untrusted execution environment through hardware, and sensitive data and corresponding execution programs can be stored in the trusted execution environment, so that security characteristics such as privacy protection, integrity protection and the like are realized while the data processing function requirements are realized. The latest CPU architecture is usually built with trusted execution environments such as Intel SGX and ARM TrustZone.
The TEE can realize the safe processing of private data and the trusted execution of codes, and the security level can ensure that instructions and data can be stored and executed in a memory space with double isolation of software and hardware, so that the execution process is extremely difficult to attack and the data is extremely difficult to tamper. Meanwhile, the TEE (such as SGX of Intel corporation) can sign the security of instruction execution, and the outside verifies the signature to confirm that the instruction result is obtained by trusted execution.
In this embodiment, the TEE is used as an execution environment of a computationally intensive operation algorithm uploaded to the cloud server by the mobile terminal.
In this embodiment, the method for a 5G mobile computing node further includes: generating a writing set of the computation force intensive operator and a feedback result; wherein the feedback results include, but are not limited to: a write set of the computation power intensive operator, a read set of the computation power intensive operator, a cloud computing result and a signature.
Step S140, calculating a local operator to obtain a local calculation result, and integrating the local calculation result and the cloud calculation result to form an instruction calculation result.
And step S150, feeding back the instruction calculation result to the external node or the designated node according to a preset rule. According to the protocol, the mobile terminal returns the instruction result to the instruction issuing node or transmits the instruction result to other nodes.
As shown in fig. 5, the overall simple flow of steps S110 to S150 and steps S210 to S220 is as follows:
1. receiving an external instruction;
2. mobile terminal instruction preprocessing, namely dividing an instruction into a plurality of independent operators, calculating rin=cin (R, op), packaging hin=hash (Rin), and taking Op as a computationally intensive operator in a base;
3. rin, hin is uploaded to a cloud server;
4. the cloud server instruction executes, and a calculation result rout=cout (R/W, op), hout=hash (Rout), and a TEE signature SigTee;
5. rout, hout, sig is downloaded to the mobile terminal;
6. after the mobile terminal obtains the cloud agent calculation result, unpacking, verifying SigTee, verifying Hash, loading Ri/Wi after verification, refreshing Wi data, and finishing a calculation instruction;
7. and finishing instruction execution and outputting a result.
In this embodiment, the method for a 5G mobile computing node further includes:
acquiring a first computation force intensive operator with the earliest time sequence, and setting a reading set of the first computation force intensive operator; after a cloud computing result of the computation force intensive operator is obtained, a second computation force intensive operator reading set with a time sequence behind is obtained according to the reading set of the first computation force intensive operator; repeating the steps, and sequentially obtaining cloud computing results of the computationally intensive operators and corresponding reading sets.
That is, in this embodiment, after the last computationally intensive operator returns to the local area in the cloud computing result, the read set of the next computationally intensive operator can be deduced and uploaded to the cloud server for computing.
For example, if the same instruction is split into multiple computationally intensive operators Opi, opj, a round of cloud agent computation is performed on the computationally intensive operator Opi with the front time sequence, after the computation result Wi is obtained, the read set Rj of the computationally intensive operator Opj with the rear time sequence is deduced at the mobile end, and then the cloud agent computation of the second round Opj is completed, so that all the computationally intensive operators are completed in sequence.
For example, the read set R3 of the computationally intensive operator Op3 may be obtained by computation of the computationally intensive operator Op 2; the read set Ri of the computationally intensive operator Opi may be computationally derived by the computationally intensive operator Opi-1. And the write set W3 of the computation force intensive operator and Wi are obtained after the computation of the cloud server is completed.
As shown in fig. 6, a detailed interaction process between the mobile terminal and the cloud server in this embodiment is shown. And (3) accessing the mMTC channel in a mass manner through the high bandwidth eMBB and the low-delay uRLLC endowed by the 5G communication, connecting the mobile terminal with a cloud server, constructing a mobile terminal +5G+cloud high-performance mobile terminal node, enabling cloud resources to be virtualized as mobile terminal background resources, enabling intensive calculation and large storage tasks to be completed by the mobile terminal to be completed in real time through the high bandwidth and low-delay 5G channel proxy to the cloud, and feeding back calculation results. The scheme can enable the household mobile phone of the user to be a high-performance computing node, realize the general computing task of block chain link points, homomorphic encryption, zero knowledge proof and other advanced password privacy protocols, and finally meet the high-strength and high-privacy requirements at the mobile terminal of the user.
The embodiment also provides a mobile terminal, which comprises a processor and a memory, wherein the memory stores program instructions; the processor executes the program instructions to implement the method applied to the mobile terminal as described above (steps S110 to S150). Wherein, the mobile terminal is a tablet personal computer, a smart phone and the like.
The embodiment also provides a cloud server, which comprises a processor and a memory, wherein the memory stores program instructions; the processor executes the program instructions to implement the method applied to the cloud server as described above (step S210 to step S220).
The embodiment also provides a server system, which comprises the mobile terminal and the cloud server. The foregoing details of the mobile terminal and the cloud server are not described herein.
The practicality of this embodiment is as follows:
today, operators are accelerating deployment of 5G communication networks, and high bandwidth, low latency communication between the cloud and the terminal devices is feasible. The cloud resources required by the mobile phone terminal have three main sources:
1. provided by the handset manufacturer. Under the condition that the storage technology and the battery utilization rate reach the limit, the manufacturer has a wish to configure the cloud resources or external cloud resources of the manufacturer for the user, so that the mobile phone can support more business scene requirements with high resource consumption. The high-speed 5G network enables local collaborative calculation and storage of cloud resources and mobile phones to be possible;
2. the user configures himself. In order to adapt to special application requirements, such as payment transactions, sales transactions, business bill processing transactions and the like, users have requirements to configure own cloud resources for mobile phones. The system designed by the embodiment can support heterogeneous node network access, and a user can quickly join an existing mobile network only by running scripts at the cloud end and the mobile end;
3. and the service party provides the service. To implement privacy services such as financial transactions, related operators may provide 5G accessed cloud resources for the service customers to implement node virtualization of customer handsets and clouds.
The technical scheme of the embodiment can cover the payment service of the mobile phone terminal, edge calculation and heterogeneous privacy identity authentication. And by customizing different intelligent contracts, the technology can be extended to Internet financial scenes of a plurality of mobile terminals, and provides a highly-reliable and private transaction mode for scenes such as payment, insurance, financial management, credit investigation and the like, so that user data ownership is ensured, occurrence of data abuse is reduced, and compliance management of mobile mutual funds is realized.
With the multi-mobile end node of the present embodiment, a network frame constructed by combining with a 5G mobile channel and a cloud TEE environment can form a decentralised blockchain network, as shown in fig. 7. The mobile terminal and the cloud environment coupled by the 5G channel can be regarded as a virtual super mobile phone terminal with high computing power and large storage, and special computing tasks which cannot be completed by common mobile phones are completed.
Specific application example 1:
as shown in FIG. 8, in this example, a multitude of merchants, users, make up a financial payment network under a blockchain architecture. The mobile terminal of the user mobile phone adopts the scheme and cloud resources to form a virtual super mobile phone terminal through a 5G channel, and the computing power is greatly improved:
1. transfer transactions between users;
2. the payment transaction between the user and the merchant can adopt a high-strength privacy transaction algorithm, such as zero knowledge proof, homomorphic encryption and multi-party security calculation, so as to protect the transaction from being acquired by non-transaction correlation.
The conventional operator with intensive computation power adopted by the privacy algorithm is preconfigured in the trusted execution environment of the cloud TEE, is subjected to high-efficiency computation by the agent to the cloud through the 5G channel algorithm, and is fed back to the mobile terminal of the user mobile phone in real time.
Because the computationally intensive algorithm is executed at the cloud, the mobile phone side does not bring performance pressure, thereby ensuring that the mobile phone can bear the full node function in the blockchain.
Specific application example 2:
as shown in fig. 9, this example implements an identification and interworking scheme for blockchain-based heterogeneous systems.
The blockchain is a chain type data processing and storage structure which packages transactions occurring within a certain time into transaction blocks and concatenates the transaction blocks in a time sequence in a cryptographic manner. The blockchain is based on a distributed architecture, running intelligent contracts that are common to multiple parties to achieve trusted execution of predetermined logic. Blockchains serve as a base device distinct from the centralization scheme, and the resulting characteristics include:
1) Distrust: trusted execution of a given contract logic can be achieved without a centralized system (or with a somewhat centralized weak centralized system).
2) Distributed multiparty billing: the parties maintain a unified book together.
3) Consensus protocol: the account can be checked by the consensus of multiple parties to each transaction, so that the account has stronger capability of resisting malicious attacks.
4) Non-tamperable: transaction posting may not be altered.
Heterogeneous system identity recognition is a difficult problem of identity management, such as the fact that personal users cannot uniformly manage and communicate with each other in Internet of vehicles, banking systems, social contact, insurance, government affairs and the like. The example adopts a blockchain scheme to realize intelligent contracts with heterogeneous identities in the contracts, and the contracts adopt a privacy algorithm ZK-Snark based on zero knowledge proof to identify user identity information and realize verification in an encryption state. The generation of ZK-Snark proving data which involves extremely high expenditure of labor cannot be realized at a common mobile phone mobile terminal.
By adopting the scheme of the embodiment, the virtual super mobile phone node of the mobile terminal can be constructed through the 5G+ cloud, so that the mobile terminal can effectively execute the ZK-Snark algorithm. Thereby supporting blockchain privacy contract identification transactions at the mobile end.
The identification of different system identities can uniformly and effectively manage heterogeneous identities of the user, the privacy of the user is ensured, and the KYC cost is reduced.
In summary, compared with the situation that the existing mobile device cannot meet the application scene requirement of intensive computing, the mobile terminal can enable the mobile phone (mobile terminal) of the user to be a high-performance computing node, realize the general computing task of block link points, encrypt homomorphic, prove zero knowledge and other advanced cryptographic privacy protocols, and finally meet the high-strength and high-privacy requirement at the mobile terminal of the user. Therefore, the application effectively overcomes various defects in the prior art and has high industrial utilization value.
The above embodiments are merely illustrative of the principles of the present application and its effectiveness, and are not intended to limit the application. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the application. Accordingly, it is intended that all equivalent modifications and variations of the application be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
