Background
Trade Secrets (Trade Secrets) refer to technical information and business information that are not known to the public, that can bring economic benefits to the rights, that have utility, and that are subject to security measures by the rights. Business secrets are property rights of an enterprise, which are related to the competitiveness of an enterprise, are critical to the development of an enterprise, and have even direct influence on the survival of an enterprise. For example, the unique recipe, ancestral sterilization of a catering enterprise, and the undisclosed unique algorithm, scheme and software of a high-tech enterprise can be trade secrets. Most businesses will not patent their own business secrets because once patented, there is a possibility of being imitated by others. But there is another risk that: if the trade secret is inadvertently revealed or independently developed by a competitor, the competitor is then preempted to register the patent, which in turn results in its inability to use the trade secret.
To prevent the occurrence of the above situation from causing the enterprise to enter into the business dilemma, one solution is to store the business secret in the form of evidence on an electronic evidence platform, and once the situation that the business secret is registered for a patent by a competitor occurs, it can be proved by the electronic evidence that the enterprise is known for a long time, so as to minimize the risk of the business. How to safely and effectively store the electronic certificate on the electronic certificate storage platform is a problem to be solved urgently.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The electronic certificate preserving and notarizing method provided by the embodiment of the invention can be applied to the application environment as shown in figure 1, and is applied to an electronic certificate preserving system which comprises a promise end, a notarizing end and a preserving end, wherein the promise end is respectively communicated with the notarizing end and the preserving end through a network. The client is also called a user end, and refers to a program corresponding to the notarization end and the storage end and providing local service for the client. The client may be installed on, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and other computer devices. The notarization terminal is a management terminal for initiating a data notarization request to the promise terminal. The storage end can be implemented by a stand-alone server or a server cluster formed by a plurality of servers.
An electronic certificate preserving and notarizing method comprises the following steps executed by a promise end:
encrypting the original data by adopting a promised encryption tool package to obtain the original encrypted data, wherein the promised encryption tool package comprises an encryption algorithm and algorithm parameters;
transmitting a data preservation instruction to a preservation end, wherein the data preservation instruction comprises a data ID corresponding to original data, the original encryption data and a promised encryption tool package;
acquiring a data notarization request sent by a notarization terminal, wherein the data notarization request comprises a notarization ID;
and acquiring corresponding public data based on the notarization ID, and sending the public data and the notarization ID to a storage terminal for notarization.
The electronic certificate preservation and notarization comprises the following steps executed by a preservation end:
receiving a data storage instruction sent by a promise end, wherein the data storage instruction comprises a data ID corresponding to original data, original encryption data and a promise encryption tool packet;
encrypting the original encrypted data and the promised encrypted tool bag by adopting a evidence encryption algorithm to obtain evidence encrypted data, and correspondingly storing the evidence encrypted data and the data ID;
receiving public data and notarization ID sent by a promise end;
acquiring corresponding evidence encryption data based on the notarization ID, decrypting the evidence encryption data to acquire original encryption data and a promised encryption tool package;
and verifying the public data by adopting the original encrypted data, if the original data corresponding to the original encrypted data is the same as the public data, acquiring a notarization result of which the public data is real data, and returning the notarization result to a notarization terminal.
In one embodiment, as shown in fig. 2, an electronic certificate preserving and notarizing method is provided, and the method is applied to the promised end and the preserving end in fig. 1 for illustration, and includes the following steps:
s11, encrypting the original data by adopting a promised encryption tool package to obtain the original encrypted data, wherein the promised encryption tool package comprises an encryption algorithm and algorithm parameters.
The promise end can adopt the existing encryption algorithm, the business secret or other important data is input into the encryption algorithm, and the output result of the algorithm is the original encryption data. I.e. the original encrypted data and the important data such as the trade secret are mutually bound.
Specifically, the present embodiment includes four independent processes that are performed in sequence: the user generates original encrypted data, the user sends the original encrypted data to the storage end, the storage end stores the original encrypted data, and finally the storage end gives a notarization result.
At least two participants in the electronic certificate storing and protecting and notarizing system are provided: a promise end and a preservation end. The examples are divided into two phases:
the promise end sends promise value of a secret message to the save end, the save end does not know the secret message (original encryption) and only knows promise value (original encryption data);
-a disclosure phase: the promise end discloses the secret message, the save end knows the secret message, and the save end can verify whether the secret message corresponds to the promise value.
The electronic certificate preservation and notarization system has two properties, the first is called hiding, which means that after the promise stage is completed, the preservation end cannot obtain any information related to secret information from promise values; the second, called binding, means that during the disclosure phase, the promised end cannot disclose another message so that the message can pass verification.
Currently, there are a number of sophisticated cryptographic algorithms, including commitments based on cryptographic hash functions, commitments based on random permutation, commitments based on encryption, etc.
Preferably, in step S11, the original data is encrypted by using a promise encryption tool package to obtain the original encrypted data, which specifically includes the following steps:
and encrypting the original data by adopting an asymmetric encryption algorithm and preset parameters to obtain the original encrypted data.
Specifically, the non-pair cryptography commitment is a public technology, and the mature commitment embodiment is applied in the embodiment. By way of example, a specific implementation of one commitment embodiment is described herein.
And (3) parameter generation: according to the safety parameter k, two different k-bit prime numbers are randomly generated to q1 and q2, N=q1q2 is calculated, a non-degenerate N-order bilinear group G is constructed, two generation elements G and H in the group and bilinear mapping e are selected, G is selected, G= > H, T=2k-1 is calculated, and output (N, T, G, H, G, H, e) is used as a public parameter.
Promise: let the trade secret be s, calculate m=hash(s), where hash: {0,1} = (0, 1} k-1 is a cryptographic hash function with an output length of k-1 bits, thus m e {0,1., T-1}, calculate c=gmhr and take C as the commitment value.
Revealing the promise: to reveal the commitment value C, (m, r) is disclosed, any verifier can verify whether C and (m, r) satisfy c=gmhr, accept the commitment if so, and reject the commitment value otherwise.
S12, sending a data storage instruction to a storage end, wherein the data storage instruction comprises a data ID corresponding to original data, the original encryption data and a promised encryption tool packet.
S21, receiving a data storage instruction sent by the promise end, wherein the data storage instruction comprises a data ID corresponding to original data, the original encryption data and a promise encryption tool packet.
Specifically, once the user's commitment information (i.e., the original encrypted data) is generated, the user sends the commitment information and the description (including preferences, etc.) of the electronic document holding and notarization system (i.e., the commitment encryption toolkit) to the document holding platform. After the information is received by the evidence storage platform, the evidence storage platform generates and stores evidence together with the description of the notarization system and the promised information, and the process is also called as 'evidence storage'.
S22, encrypting the original encrypted data and the promised encrypted tool package by adopting a evidence encryption algorithm, obtaining evidence encrypted data, and storing the evidence encrypted data and the data ID correspondingly.
Preferably, after step S22, the electronic proof keeping and notarization further comprises the steps of:
and packaging the evidence encryption data and the data ID to form an evidence packet, and sending the evidence packet to each node of the preset blockchain for storage.
Specifically, in the process of evidence storage, the storage end can adopt a blockchain technology to ensure the non-tamper property of the evidence packet.
The storage end can use a hash operation module (i.e. evidence encryption algorithm) to carry out hash operation on the promised information uploaded by the promised end, and generate a section of hash value with fixed length to form hash value coded data; next, the storage end digitally signs the generated hash value by adopting a digital signature algorithm, and sends the public key and hash value coded certificate data with a private key signature to the blockchain network; the block chain network is used for carrying out one-time consensus on the uploading date of the hash value coded certificate data, the public key of an uploading person and the hash value coded certificate data with a private key signature, packaging the hash value coded certificate data into blocks, and synchronously transmitting the blocks to each node in the network to realize distributed storage.
S13, acquiring a data notarization request sent by a notarization terminal, wherein the data notarization request comprises a notarization ID.
S14, acquiring corresponding public data based on the notarization ID, and sending the public data and the notarization ID to a storage terminal for notarization.
S23, receiving the public data and the notarization ID sent by the promise end.
Specifically, the certification process includes four steps: firstly, a storage end discloses stored evidence, namely promise information uploaded by a user, electronic evidence storage and description of a notarization system; the user then discloses his own trade secret (i.e., raw data); next, any party (including a third party) can verify that the trade secret information revealed by the promise end and the promise information are identical, thereby confirming that the revealed trade secret is really already known by the promise end; finally, the similarity comparison of the trade secrets is carried out to verify whether the trade secrets and infringement techniques claimed by the promised end are similar and the degree of similarity.
S24, acquiring corresponding evidence encryption data based on the notarization ID, and decrypting the evidence encryption data to acquire original encryption data and a promised encryption tool package.
S25, verifying the public data by adopting the original encrypted data, if the original data corresponding to the original encrypted data is identical to the public data, obtaining a notarization result that the public data is real data, and returning the notarization result to the notarization terminal.
In one embodiment, as shown in fig. 3, in step S25, the original encrypted data is used to verify the public data, and if the original data corresponding to the original encrypted data is the same as the public data, the method specifically includes the following steps:
s251, encrypting the public data by adopting a promise encryption tool package to obtain notary encrypted data.
S252, adopting a data comparison tool to compare the consistency of the notarized encrypted data and the original encrypted data.
S253, if the notarized encrypted data and the original encrypted data are consistent, the original data corresponding to the original encrypted data are identical to the public data.
In one embodiment, as shown in fig. 4, after step S22, that is, after storing the evidence-encrypted data and the data ID, the electronic certificate store and the notarization further include the steps of:
s221, if the third party designates the notarization terminal, receiving the public data and the notarization ID sent by the promised terminal;
s222, acquiring corresponding evidence encryption data based on the notarization ID, decrypting the evidence encryption data to acquire original encryption data and a promised encryption tool package;
s223, generating a data notarization request, wherein the data notarization request comprises a notarization ID, original encrypted data and a promised encrypted tool package, and sending the data notarization request to a notarization terminal for notarization.
In the electronic certificate preserving and notarizing method provided by the embodiment, the promise end encrypts the original data to obtain the original encrypted data, and simultaneously sends an encryption tool kit and the original encrypted data to the preserving end for preserving; when the promise end receives a data notarization request sent by the notarization end, simultaneously sending the notarization ID and corresponding open data to the storage end for verification, and obtaining corresponding evidence encryption data based on the notarization ID by the storage end, and decrypting to obtain original data; when the original data and the public data are the same, the public data can be considered as a real notarization result, the promise end stores the original data to the storage end in the form of original encrypted data, so that confidentiality, unpublishability and safety of the original data can be enhanced, meanwhile, the original data is obtained by decrypting the original encrypted data to be compared with the public data, and the authenticity and reliability of the comparison result can be ensured.
The embodiment solves the privacy problem when the trade secret is subjected to electronic certification by using the cryptography promise embodiment. The embodiment can effectively help a user to form electronic evidence about the trade secret on the premise that the trade secret is not disclosed to the evidence-preserving platform.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
