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 electronic evidence storing and notarization method provided by the embodiment of the invention can be applied to the application environment shown in fig. 1, and is applied to an electronic evidence storing system, wherein the electronic evidence storing system comprises a commitment end, a notarization end and a storing end, and the commitment end is respectively communicated with the notarization end and the storing end through a network. The client is also called a user side, and refers to a procedure corresponding to the notarization side and the storage side and providing local services for the client. The client can be installed on computer equipment such as but not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable equipment. The notarization end is a management end used for initiating a data notarization request to the commitment end. The storage side can be implemented by an independent server or a server cluster consisting of a plurality of servers.
An electronic deposit certificate storage and notarization method comprises the following steps executed by a commitment end:
encrypting original data by adopting a committed encryption tool package to obtain the original encrypted data, wherein the committed encryption tool package comprises an encryption algorithm and algorithm parameters;
sending a data storage instruction to a storage end, wherein the data storage instruction comprises a data ID corresponding to the original data, the original encrypted data and a committed encryption tool kit;
acquiring a data notarization request sent by a notarization end, 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.
An electronic deposit certificate storage and notarization comprises the following steps executed by a storage terminal:
receiving a data saving instruction sent by a commitment end, wherein the data saving instruction comprises a data ID (identity) corresponding to original data, original encrypted data and a commitment encryption tool kit;
encrypting the original encrypted data and the promised encryption tool package by adopting an 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 commitment end;
acquiring corresponding evidence encryption data based on the notarization ID, and decrypting the evidence encryption data to acquire original encryption data and a commitment encryption tool kit;
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 with the public data as real data, and returning the notarization result to a notarization end.
In an embodiment, as shown in fig. 2, an electronic deposit certificate storage and notarization method is provided, which is described by taking the example that the method is applied to the committee and the storage in fig. 1, and includes the following steps:
s11, encrypting the original data by adopting a committed encryption tool package to obtain the original encrypted data, wherein the committed encryption tool package comprises an encryption algorithm and algorithm parameters.
The promising end can adopt the existing encryption algorithm, and inputs the trade secret or other important data into the encryption algorithm, and the output result of the algorithm is the original encryption data. That is, the original encrypted data and the important data such as the trade secret are bound to each other.
Specifically, the present embodiment includes four independent processes performed in sequence: the user generates original encrypted data, the user sends the original encrypted data to the storage terminal, the storage terminal stores the original encrypted data and finally the storage terminal gives a notarization result.
There are at least two parties in the electronic deposit and notarization system: a commitment end and a preservation end. The example is divided into two stages:
the stage of commitment, in which the commitment end sends the commitment value of a secret message to the holding end, and the holding end does not know the secret message (original encryption) and only knows the commitment value (original encryption data);
-an disclosing phase: the prompter discloses the secret message, and the keeper knows the secret message, so that the keeper can verify whether the secret message corresponds to the prompter.
The electronic evidence storage and notarization system has two properties, the first is called hiding, which means that after the commitment stage is completed, the storage end can not obtain any information related to secret information from the commitment value; the second is binding, which means that during the publishing phase, the committing party cannot publish another message so that the message can be verified.
Currently, there are a number of sophisticated cryptographic algorithms, including cryptographic hash function based commitments, random permutation based commitments, encryption based commitments, and the like.
Preferably, in step S11, encrypting the original data by using the committed encryption kit to obtain the original encrypted data 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, a technique that is not public to cryptographic commitment is adopted, and a mature commitment embodiment is only applied in this embodiment. By way of example, a specific implementation of one promising embodiment is described herein.
Parameter generation: according to a safety parameter k, two different k-bit prime numbers q1 and q2 are randomly generated, N is q1q2 is calculated, a non-degenerate N-order bilinear group G is constructed, two generating elements G and H in the group and a bilinear map e are selected, G is G H, T is 2k-1 is calculated, and (N, T, G, H, G, H, e) is output as a public parameter.
The commitment is that the commercial secret is s, m-hash(s) is calculated, wherein, hash is {0,1} - } {0,1} k-1 is a cryptographic hash function with the output length of k-1 bits, so m ∈ {0,1.
Revealing the commitment: to reveal the commitment value C, (m, r) is disclosed, and any verifier can verify whether C and (m, r) satisfy C-gmhr, accept the commitment if satisfied, or reject the commitment value otherwise.
And S12, sending a data storage instruction to a storage end, wherein the data storage instruction comprises a data ID corresponding to the original data, the original encrypted data and a committed encryption tool kit.
And S21, receiving a data storage instruction sent by a commitment end, wherein the data storage instruction comprises a data ID (identity) corresponding to original data, original encrypted data and a commitment encryption tool kit.
Specifically, once the commitment information (i.e., the original encrypted data) of the user is generated, the user sends the commitment information and the description (including parameter selection and the like) of the electronic deposit certificate storage and notarization system (i.e., the commitment encryption kit) to the deposit certificate platform. After receiving the information, the evidence storage platform generates and stores evidence together with the description of the electronic evidence storage and notarization system and the commitment information, and the process is also called 'evidence storage'.
And S22, encrypting the original encrypted data and the promised encryption tool kit by adopting an evidence encryption algorithm to obtain evidence encrypted data, and correspondingly storing the evidence encrypted data and the data ID.
Preferably, after step S22, the electronic deposit certificate storage 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 block chain for storage.
Specifically, in the process of evidence preservation, the preservation end may adopt a block chain technique to ensure the non-tamper-ability of the evidence package.
The storage end can use a hash operation module (namely an evidence encryption algorithm) to carry out hash operation on the promised information uploaded by the promised end and generate a segment of hash value with fixed length to form hash value coded data; secondly, the storage end digitally signs the generated hash value by adopting a digital signature algorithm, and sends the public key and the hash value coding evidence storage data with the private key signature to the block chain network; the block chain network is used for packaging the uploading date of the hash value coding certificate storage data, the public key of an uploader and the hash value coding certificate storage data with the private key signature into blocks after one-time consensus and synchronously sending the blocks to each node in the network to realize distributed storage.
And S13, acquiring a data notarization request sent by a notarization end, 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.
And S23, receiving the public data and the notarization ID sent by the commitment end.
Specifically, the process of certification includes four steps: firstly, a storage end discloses stored evidence, namely commitment information uploaded by a user, electronic evidence storage and description of a notarization system; the user then wants to disclose his own business secrets (i.e. raw data); next, any party (including a third party) can verify that the business secret information revealed by the committing party and the commitment information are consistent, thereby confirming that the revealed business secret is indeed already known by the committing party; finally, similarity comparison of the business secrets is carried out to verify whether the technologies of the business secrets and infringement claimed by the commitment end are similar and the similarity degree is high.
And S24, acquiring corresponding evidence encryption data based on the notarization ID, and decrypting the evidence encryption data to acquire original encryption data and a committed encryption tool kit.
And S25, 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 with the public data as real data, and returning the notarization result to a notarization end.
In an embodiment, as shown in fig. 3, in step S25, the public data is verified by using the original encrypted 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:
and S251, encrypting the public data by adopting a promise encryption tool kit to obtain notarization encrypted data.
And S252, comparing the consistency of the notarization encrypted data and the original encrypted data by using a data comparison tool.
And S253, if the notarization encrypted data is consistent with the original encrypted data, the original data corresponding to the original encrypted data is the same as the public data.
In one embodiment, as shown in fig. 4, after step S22, i.e. after storing the evidence encryption data and the data ID correspondingly, the electronic deposit certificate and notarization further comprises the following steps:
s221, if the third party is designated as a notarization end, public data and a notarization ID sent by a commitment end are received;
s222, acquiring corresponding evidence encryption data based on the notarization ID, and decrypting the evidence encryption data to acquire original encryption data and a committed encryption tool kit;
and S223, generating a data notarization request, wherein the data notarization request comprises a notarization ID, original encrypted data and a committed encryption kit, and sending the data notarization request to a notarization terminal for notarization.
In the electronic storage and notarization method provided by this embodiment, the committing end encrypts the original data to obtain the original encrypted data, and sends the encryption toolkit and the original encrypted data to the storage end for storage; after receiving a data notarization request sent by a notarization end, a commitment end sends a notarization ID and corresponding air-opened data to a storage end for verification, and the storage end can obtain corresponding evidence encrypted data based on the notarization ID and decrypt the evidence encrypted data 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 prompter stores the original data to the storage end in the form of original encrypted data, so that the confidentiality, the undisclosed property and the safety of the original data can be enhanced, and meanwhile, the original data and the public data are obtained by decrypting the original encrypted data to be compared, so that the authenticity and the reliability of a comparison result can be guaranteed.
