Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an information processing method, apparatus, and communication equipment. Background Technology

[0002] Currently, massive amounts of data are often outsourced to cloud platforms for storage. However, the centralized storage and processing architecture of cloud server systems leads to severe bandwidth and energy consumption issues and makes them potential targets for attackers, resulting in single points of failure. Therefore, edge computing, extending cloud computing to the network edge, has emerged. This allows data to be processed on edge computing platforms near the user, eliminating the need for data to be transferred between devices and the cloud, enabling real-time data processing and feedback locally. Simultaneously, to more efficiently utilize the massive distributed computing resources at the network edge and promote the deep integration and collaborative processing of distributed edge computing and the network, the concept of computing power networks has been proposed.

[0003] Computing power networks aim to interconnect and coordinate distributed computing nodes, optimizing and efficiently utilizing network and computing resources through improvements to network architecture and protocols. However, the security of computing power nodes cannot be guaranteed, and direct computation may lead to the leakage of data, computation processes, and results. Existing technologies have provided some data authentication schemes to address this, but the following problems still exist:

[0004] 1. Some solutions only guarantee the integrity of the data, but cannot verify its specific source, lack traceability, and still have low security.

[0005] 2. Some schemes only use the simplest ECDSA elliptic curve signature, which has low signing efficiency and cannot guarantee the trustworthiness of the verification public key, thus also posing security risks.

[0274] The following is an example of the information processing method provided in the embodiments of the present invention. The signatures involved above are digital signatures, specifically BLS signatures.

[0275] To address the aforementioned technical problems, embodiments of the present invention provide an information processing method, specifically a data authentication scheme for computing power networks based on BLS signatures and blockchain. This scheme can efficiently verify the computation process and results within the computing power network, ensuring the confidentiality, integrity, and non-forgeability of data and computation parameters. Specifically, the system architecture for implementing this scheme can be as follows: Figure 4 As shown, it involves four functional modules: a data owner module (corresponding to the aforementioned data owner node), a user module (corresponding to the aforementioned terminal), a computing power network module (corresponding to the aforementioned computing power network equipment), and a blockchain module (corresponding to the aforementioned blockchain); among which:

[0276] (1) The data owner module can be used to store the original data and generate confidentiality parameters (corresponding to the confidentiality parameter information mentioned above); and send relevant information to the user (corresponding to the user module) and the computing power network module respectively based on the original data and confidentiality parameters (corresponding to sending the original data to the terminal, sending the first information to the terminal according to the confidentiality parameter information, and sending the second information to the computing power network device).

[0277] (2) The user module can be used to receive raw data and upload the data signature (corresponding to the first signature mentioned above) to the computing power network (corresponding to the computing power network module) for calculation. At the same time, the user needs to obtain the final correct calculation result (corresponding to the first calculation result mentioned above).

[0278] (3) The computing power network module can be used to authenticate the transmitted data to ensure the confidentiality and integrity of the data; and through the computing power network's own mechanism, it can select the optimal node for computation and obtain the computation result according to the corresponding computation function (corresponding to the first computation result mentioned above); it can also hide the computation result with cryptographic commitment (corresponding to the above-mentioned encapsulation and hiding of the first computation result according to the cryptographic commitment function information in the second information to obtain the processed first computation result), merge it with the computing power node identity information to sign (corresponding to obtaining the second signature according to the processed first computation result and the identity information of the target computing power node, etc.) and put it on the chain.

[0279] (4) The blockchain module can be used to store the signature data (corresponding to the second signature mentioned above) transmitted by the computing power nodes, ensuring that it cannot be tampered with and is traceable. Users can verify the signature information stored in the blockchain to obtain what they need.

[0280] Based on the above, such as Figure 4 As shown, this solution may specifically include the following:

[0281] Part One, the Data Owner Module, is used to store the original data, generate confidentiality parameters corresponding to the original data, and send the original data and at least a portion of the confidentiality parameters to the User Module, as well as to send at least a portion of the confidentiality parameters to the Computing Power Network Module. Specifically, this may involve the following operations:

[0282] 1. The data owner DO generates a security parameter param (i.e., a confidential parameter corresponding to the original data) and sends information to each participant accordingly. The security parameter can be represented as: param = {e(u,v), H(), Com(), pk1, sk1, pk2, sk2}, where e(u,v) is a bilinear mapping (corresponding to the above bilinear mapping information, specifically the bilinear mapping related parameter information), specifically assuming g is a parameter in the bilinear mapping; Com() is a cryptographic commitment algorithm (corresponding to the above cryptographic commitment function information, specifically the cryptographic commitment function related parameter information), which can be used to hide key information (such as the above first calculation result); H() is a hash function (corresponding to the above hash function information, specifically the hash function related parameter information), pk1 and sk1 are the public key (corresponding to the above second public key) and private key (corresponding to the above second private key) of the user module, respectively, and pk2 and sk2 are the public key (corresponding to the above first public key) and private key (corresponding to the above first private key) of the computing power network module, respectively. For both pairs of keys, g can be obtained. sk =pk (for example) g represents a security parameter in the bilinear mapping. At this point, the security parameter generation phase is complete.

[0283] Subsequently, the data owner (module) can disclose information such as e(u,v) and H(); specifically, in the security parameters, except for the private key, all other information can be disclosed to all participants; for example, sk1 is only sent to the user module and not disclosed to other participants (such as the computing power network module); while sk2 is only sent to the computing power network module and not disclosed to other participants (such as the user module).

[0284] 2. The data owner DO will store the dataset D = {d1, d2, ... d...} n Send to User (user). This solution assumes the user has already established trust with the data owner. Where d... i The following explanation uses a single data point (corresponding to the original data mentioned above) as an example to illustrate the operation performed on the computing network.

[0285] Part Two, the user module, can be used to generate a corresponding first signature based on the received raw data, using a hash function (corresponding to the hash function information in the first information mentioned above) and a first public key (corresponding to the first public key in the first information mentioned above), and send the first parameter corresponding to the first signature (corresponding to the first parameter information mentioned above) to the computing power network module. Specifically, this may involve the following operations:

[0286] 3. User's view on (raw) data d i First, using a hash function (corresponding to the hash function information in the first information above) and the public key of the computing power network module C (corresponding to the first public key in the first information), a (first) signature Sig1 is generated, which can be specifically represented as follows: Among them, ID U For the User's identity information, TS1 is the current timestamp (corresponding to the second timestamp mentioned above). Next, the first parameter corresponding to the first signature can be... <ID U ||TS1||Sig1||d i >Sent to computing network module C.

[0287] Part Three, the computing power network module, is used for time and user authentication based on the first parameter (corresponding to the second authentication mentioned above). When authentication is successful, it acquires the original data and uses the optimal computing power node (corresponding to the target computing power node mentioned above) to calculate the original data, obtaining a first calculation result and performing anonymization processing to obtain the processed first calculation result. Simultaneously, it generates a second signature based on a hash function (corresponding to the hash function information in the second information mentioned above) and a first private key (corresponding to the first private key in the second information mentioned above), and sends the second parameter corresponding to the second signature (corresponding to the second parameter information mentioned above) to the blockchain module. Specifically, this may involve the following operations:

[0288] 4. The computing power network module verifies whether the time parameter in the first parameter (corresponding to the second timestamp mentioned above) is within a valid range; it verifies the user's identity information based on the user identity parameter (corresponding to the identity information of the terminal mentioned above) to determine whether the user has registered in the computing power network; furthermore, when e(g,Sig1)=e(pk1,H(ID) exists... U When ||pk2||Sig1)), it indicates that the first signature verification was successful (corresponding to the above-mentioned bilinear mapping verification of the first signature based on the terminal's identity information, and the bilinear mapping information, first public key, second public key, and hash function information in the second information); when all verifications are successful, the original data d can be obtained. i ;

[0289] Specifically, after receiving the first parameter sent by the user, the computing network module C first verifies whether the timestamp (corresponding to the second timestamp) is within a valid range, and then verifies the user's identity information (corresponding to the terminal's identity information), which is equivalent to confirming whether the user has registered in the computing network. Furthermore, the computing network module C can use the bilinear mapping e(u,v) to verify the equation e(g,Sig1)=e(pk1,H(ID)). U Does ||pk2||Sig1) hold true (corresponding to the above-mentioned bilinear mapping verification of the first signature based on the terminal's identity information, and the bilinear mapping information, first public key, second public key, and hash function information in the second information)? If true, the signature verification is successful. Specifically, the derivation of this equation is as follows:

[0290] Because the public key of the computing network module is bound to a hash function, there is no possibility of attack by forging the public key. After successful signature verification, the computing network can obtain the original data d. i .

[0291] In this solution, "verifying identity information" can specifically refer to verifying the security of the identity information; subsequently, after successful signature verification, the user's identity information ID... U It can be registered in the computing power network.

[0292] 5. The computing power network module obtains the raw data d. i Then, based on the computing power network's own mechanism, the optimal computing power node (corresponding to the aforementioned target computing power node, with identity information as ID) is selected. C For the original data d iThe calculation yields a first calculation result RS. Based on a cryptographic function (corresponding to the cryptographic commitment function information in the second information above), the first calculation result RS is encapsulated and concealed to obtain the processed first calculation result Com(RS). Then, a second signature can be generated based on a hash function (corresponding to the hash function information in the second information above) and a first private key, where the first private key is the private key corresponding to the computing power network device. The second parameter corresponding to the second signature is then sent to the blockchain module.

[0293] Specifically, the computing network module C obtains the data to be operated on, d. i Then, the optimal computing power node (identity information is ID) can be selected using the computing power network's own mechanism. C The computational network module C performs calculations to obtain the first calculation result RS. Then, the computing network module C can first encapsulate RS using a cryptographic function (corresponding to the cryptographic commitment function information in the second information above) to obtain Com(RS) (corresponding to the first calculation result after processing), thus concealing its (RS) information. Next, the computing network module C can use a hash function (the hash function information in the second information) and the private key of the computing network device (corresponding to the first private key above) to generate a (second) signature Sig2, which can be specifically represented as... And based on this, the second parameter information <TS2||Sig2||ID C ||Com(RS)> is sent to blockchain module B (i.e., transmitted to the blockchain); in this scheme, the parameters are directly uploaded to the chain, so the parameters cannot be tampered with or forged, and the traceability of the parameters is guaranteed. TS2 in the second parameter information corresponds to the first timestamp mentioned above, which is the real-time timestamp when the second signature is generated.

[0294] Part 4, the blockchain module, can be used to store the second signature data.

[0295] Part 5, the user module, can also be used for verification based on the second signature (corresponding to the first verification mentioned above). When the verification is successful, the processed first calculation result is obtained. Subsequently, the user can perform commitment verification based on the second calculation result sent by the computing power network module, the result commitment verification parameters, and the processed first calculation result. If the verification is successful, the first calculation result can be obtained. Specifically, the following operations may be involved:

[0296] 6. The user module verifies the second signature. Specifically, when e(g,Sig2)=e(pk2,H(ID) exists... CWhen ||Com(RS)||TS2)), the second signature verification is successful (corresponding to the above bilinear mapping verification of the second signature based on the bilinear mapping information, hash function information and first public key in the first information, as well as the identity information of the target computing node, the first timestamp and the target calculation result), then the processed first calculation result Com(RS) is obtained.

[0297] Specifically, users can view the second signature on the blockchain and verify it. In this scheme, the blockchain, as a storage medium, ensures the immutability and traceability of the parameters. Regarding "signature verification," it can specifically include: after the timestamp TS2 is verified, the verifier (user) verifies the signature, i.e., verifying the equation e(g,Sig2)=e(pk2,H(ID)). C If ||Com(RS)||TS2)) is true, then the verification is successful, and the verifier obtains the identity information as ID. C The target computing power node is for data d i The computation result contains the hidden information Com(RS), and all of the above information is authenticated and cannot be tampered with. At this point, due to the confidentiality of the computation result, cryptographic commitments are used to protect its privacy, ensuring that non-participating parties cannot obtain specific information about the result.

[0298] 7. The user module generates Com′(RS) based on the second calculation result RS′ sent by the computing power network module and the result commitment verification parameter p. When there exists Com′(RS) = Com(RS), it proves that the commitment verification is successful, and then the first calculation result RS is obtained.

[0299] Specifically, the user performs the result commitment verification. When the verifier (user) desires the specific result RS, they need to open and verify the commitment (corresponding to Com(RS)). The computing power network can publish the computation result RS′ (corresponding to the second computation result mentioned above, which can theoretically be equal to RS) or send it to the registered user through a covert channel (depending on the specific scenario), and send the confidential parameter p required to generate the commitment (corresponding to the result commitment verification parameter mentioned above). After receiving RS′ and p, the user can generate Com′(RS) using a cryptographic function (corresponding to the cryptographic commitment function information in the first information mentioned above). Then, the user checks whether Com′(RS) is the same as the Com(RS) stored on the chain. If they are the same, the commitment verification is successful, proving that the result has been modified by the computing power node, and the user obtains the correct result RS. At this point, the scheme is completed.

[0300] Therefore, the solutions provided by the embodiments of the present invention involve:

[0301] 1. Data Authentication Method for Computing Power Networks Based on BLS Signatures and Blockchain: This solution uses blockchain technology and BLS digital signature technology to authenticate the parameters flowing in the computing power network. At the same time, it makes a cryptographic commitment to the calculation results and puts them on the chain, which not only ensures the integrity of the data and confirms the source of the data, but also ensures the trustworthiness of the public key, which has great protection value.

[0302] 2. This scheme uses cryptographic commitments to ensure the confidentiality of computation results in the computing power network. That is, it not only authenticates the identity but also protects the privacy of the computation results. Only when the integrity and source are guaranteed can the commitment be opened and verified at the appropriate time to obtain the computation results, which has great protective value.

[0303] 3. Authentication Method: This scheme binds the verifier's public key (specifically bound to the hash function) to the signature, ensuring the trustworthiness of the public key and preventing forgery for signature verification. It also binds a timestamp to prevent replay attacks and the identity information of the computing power node, clearly identifying the computing party and preventing forgery of computing power nodes or their repudiation. Simultaneously, the blockchain serves as a storage medium in this scheme, ensuring the parameters are immutable and traceable, but is not used for actual verification, thus improving efficiency. This can also be understood as:

[0304] This solution is based on blockchain technology and BLS digital signature technology. It utilizes the public key, timestamp, and identity information of the target computing node bound to the user to ensure that the public key cannot be forged for signature verification, prevent replay attacks, and prevent forged computing nodes from performing calculations or denying their existence. It also makes a cryptographic commitment to the calculation result to ensure data integrity and data source. At the same time, when obtaining the final calculation result, it is further verified according to the commitment to the calculation result to further reduce the possibility of leakage of the calculation result. Furthermore, the blockchain, as a storage medium, can ensure that the signature parameters cannot be tampered with and are traceable. It is not used for specific verification, thus improving efficiency.

[0305] Specifically, this solution uses blockchain technology and BLS digital signature technology to authenticate time and user identity information based on signature parameters in the computing power network module, ensuring data integrity. Furthermore, the calculated results are encrypted to ensure confidentiality. At the same time, the blockchain module is used to store data, which ensures that the parameters cannot be tampered with and are traceable, without being used for specific verification, thus improving efficiency.

[0306] In summary, the solution provided by the embodiments of the present invention has the following advantages:

[0307] 1. This solution not only authenticates the data flowing in the computing network to ensure data integrity, but also puts the signature on the blockchain to ensure data traceability, meaning that adversaries cannot launch attacks by forging signatures.

[0308] 2. This scheme authenticates the identity information of nodes, clarifies the identity of the computing party, and prevents forged computing power nodes from performing calculations or their denial; at the same time, it encapsulates the calculation results with cryptographic commitments to protect the confidentiality of the results and prevent non-participating parties from maliciously stealing the results.

[0309] 3. This solution utilizes BLS digital signatures and blockchain authentication, with the blockchain serving merely as a storage medium. Compared to using ECDSA signatures for authentication, this significantly improves efficiency and eliminates the need for smart contract verification, making it more valuable for application.
