Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
Fig. 1 shows a highly reliable electronic contract signing method based on autonomous federation chain technology, which includes the following steps: s1: and the contract signing parties perform online registration to obtain the corresponding centralized login account, the login password, the decentralized identity ID and the corresponding secret key. S2: the contract signing parties edit and confirm the contract content. S3: and (4) leading the official certification electronic seal by both contract signing parties to carry out online contract signing on the confirmed contract content to obtain the electronic contract. S4: and encrypting the electronic contract with the signing block chain time stamp by using the key corresponding to the two signing parties. S5: and storing the encrypted electronic contract into a alliance chain and synchronizing the copy of the encrypted electronic contract into a server cache unit. S6: and storing the whole-course online signing data of the electronic contract into a alliance chain. Through the steps, the online editing and signing of the electronic contract are supervised, and the data is controllable in the whole process. The above steps are specifically described below.
For step S1: and the contract signing parties perform online registration to obtain the corresponding centralized login account, the login password, the decentralized identity ID and the corresponding secret key.
Specifically, the signing parties register online, and the electronic signing platform distributes a one-to-one corresponding centralized login account number, a login password, a decentralized Identity (ID) and a corresponding secret key for the signing parties. The decentralized identity ID is a decentralized identity framework which accords with the W3C standard, is hooked with a federation link address of the platform, and belongs to an account mechanism. It is used to generate numbers, cryptographically based identity IDs and assign them to different signing parties, certification authorities. The decentralized identity ID integrates various authentication service organizations, establishes multi-source authentication and realizes the authentication of both parties signing the contract and the validity of the contract.
In the application, a secret key generated in an online registration process of a partner and a signer is safely managed through a threshold algorithm (threshold scheme).
In the registration process, a mTLS (mutual Transport Layer Security) Security mechanism based on a zero trust Security framework is adopted in the verification process with the centralized certification authority to ensure the communication Security, and a verification signature is required between each pair of services to ensure the certification and data Security.
It can be understood that in the registration process, multi-system cross verification is further performed through living body detection, a face comparison biometric identification technology, a certificate OCR identification technology and a signing sworn module, authenticity of identity information of a user is verified, the user is verified to be a real person and a person, and the contract is ensured to meet 'real will, real identity'.
For step S2: the contract signing parties edit and confirm the contract content.
In the process of editing and confirming contract contents by contract signing parties, a unique identification code is distributed to each version of contract, the unique identification code is stored in an intelligent contract of a alliance chain, and the contract contents corresponding to the unique identification code are stored in the alliance chain and a server cache unit. If the client needs to roll back to the previous version contract, the historical version recovery operation can be executed, and the signing platform will fetch the historical contract from the high-performance server cache module and present the historical contract to the user. The repetitive input and output of the user is greatly reduced.
For step S3: and (4) leading the official certification electronic seal by both contract signing parties to carry out online contract signing on the confirmed contract content to obtain the electronic contract.
The electronic seal includes an electronic official seal and a personal seal.
It can be understood that the contract content can be signed by signing the name online, and the signing process is recorded in real time and is bound with the signed contract.
For step S4: and encrypting the electronic contract with the built-in signing block chain time stamp by using a key corresponding to the signing parties.
After the both parties of signing confirm the contract terms and the electronic official seal signature, the electronic contract can be generated on line. At this time, the electronic contract is internally provided with a signing blockchain timestamp. The electronic contract is then encrypted using the keys corresponding to the signing parties.
For step S5: and storing the encrypted electronic contract into a alliance chain and synchronizing the copy of the encrypted electronic contract into a server cache unit.
In the application, a high-performance alliance technology is adopted, all signed contracts are stored in an alliance chain system, so that the non-tampering property of all data can be ensured, and two major factors of ' original text not modified and ' signature not modified ' are ensured. Meanwhile, the contract storage management module is also provided with a high-performance server cache module, and the electronic contract copies stored in the alliance chain are synchronized to the high-performance server cache module. When both signing parties want to download and check, the both signing parties can download through the cache module, and the rapid demand and downloading experience of users are guaranteed. When downloading, the electronic contract in the cache module generates a hash value to be compared with the electronic contract stored in the alliance chain in a consistency mode.
In this application, the high performance federation chain employs an original SBFT (Super BFT) consensus algorithm. The SBFT is a hybrid algorithm that combines proof of merit, verifiable random functions, and byzantine fault-tolerant algorithms. The SBFT algorithm is improved on the traditional Byzantine Fault Tolerance (BFT) algorithm, a randomness factor is added into a consensus algorithm, and the set of a proposal node, a verification node and a confirmation node which are in consensus in each round of blocks are different. This makes the algorithm able to resist malicious attacks, ensuring the security of the signing platform. The randomness factor value of each chunk is determined by the previous consensus chunk, taking the transaction information from the previous chunk and calculating 1024 times the hash value, which is then used as the value for the next chunk.
The high-performance alliance chain supports a cross-chain protocol and can support access to government affair chains and enterprise chains.
For step S6: and storing the whole-course online signing data of the electronic contract into a alliance chain.
And the electronic contract signs the data on line, leaves marks in the whole process and stores the data for evidence, and the data are stored by using a block chain technology and cannot be modified in the later stage.

and synchronously storing the electronic contract and the whole-course online signing data thereof to an external notary and judicial department.
Here, the external notary and judicial departments include, but are not limited to, notary offices, electronic data security centers, internet courts, arbitration committees, CA agencies, and the like. The data evidence storing technology is highly approved by notarization departments and judicial certification centers, and can directly apply for judicial evidence production online.
Specifically, a mTLS security mechanism based on a zero trust security framework is adopted for data communication with an external notarization department, so that the communication security is ensured.
