Description
Technical Field
The invention relates to the technical field of block chains, in particular to a CA (conditional access) and Key (Key) removing electronic signature and electronic contract system based on a block chain.
Background
The blockchain is the 5 th revolution following the steam engine revolution, the electrical revolution, the information revolution and the internet revolution; however, the blockchain revolution is more profound than the above four revolution, because the former four revolution is the revolution of "things and technology", and the blockchain revolution is the revolution of "thinking way, methodology and framework". The regulations on several problems of the trial and management case of the internet court, released by the highest people court in 2018, 9/3, specify that: the electronic data submitted by the party can be authenticated through evidence collection, fixing and tamper-proof technical means such as electronic signature, trusted timestamp, hash value verification, block chain and the like or through electronic evidence obtaining and storing platform authentication, and the authenticity of the electronic data can be proved, and the internet court should be confirmed. ".
Basic law of blockchains:
1. block chain first law: and (3) humanization removal: behaviors or consensus cannot rely on conscious "people" or human-to-human verbal or written agreements, can rely only on "things", and can rely only on "CPUs and algorithms" in the world of networks;
2. blockchain second law: automatically executing: contracts, processes and transactions are automatically driven by the CPU and algorithms, rather than by conscious persons;
3. block chain third Law: decentralization and disintermediation: point-to-point direct trading (P2P), without the need for "intermediaries" and "hubs";
4. blockchain fourth law: sharing and sharing: the method has the advantages that the method is jointly maintained and supervised, and information and resources are shared, so that the pain points of centralized 'central monopoly', 'single-point collapse risk', 'information asymmetry' and 'data tampering and counterfeiting' are solved;
5. blockchain fifth law: the cooperation is realized through consensus, and the problems of centralized unfair decision making and decentralized behavior incoordination among nodes are solved;
6. block chain sixth Law: the system has the advantages that a sustainable and complete supervision closed loop is adopted, and the problem of centralization of who supervises a supervisor is solved;
7. blockchain seventh law: the method is transparent, open and open, and solves the problem of centralized 'opaque center black screen';
8. block chain eighth Law: source, cross-certification and non-tamper: the data can obtain unprecedented strong trust endorsements, and the accuracy is high;
the current generation electronic signature and electronic signature technology has the following pain points and disadvantages:
1. third party centralized and mediated digital Certificate Authorities (CAs) are relied upon to establish mutual trust of the signing and signing parties. The existing digital certificate businessman CA system belongs to weak trust endorsements and has the following limitations:
1.1 signatures and identity data are susceptible to tampering in a centralized CA system;
1.2 the centralized CA system has the possibility of centralized blackcurtain, the benefit of the center is maximized, and the possibility of collusion with a counterfeiter can be realized in extreme cases;
1.3 centralized CA system is possible to have single point collapse risk;
1.4 the existing CA system has theoretical incompleteness, can't solve the problem of supervising supervisor, can't form the closed loop of supervision and authentication: the CA is a hierarchical authentication system, the upper CA (or RA) authenticates the lower CA, and the credit of the entire CA chain is guaranteed by the root of the CA, but the problem is that: who comes to supervise and authenticate the root of the CA?
The 1.5 CA service is an additional cost added to the signing activity, accounting for about 50% of the total signing cost.
2. The lack of a uniform electronic signature standard ensures mutual signing and verification among all electronic signature systems;
3. the hardware basis of the existing electronic signature system is Key (shield), but Key (shield) has the following three major problems: extra burden of keeping and carrying, poor safety problem of user experience: the device is easy to lose and steal, thereby causing subscription imitation; key (shield) is an extra cost for the user.
Disclosure of Invention
In view of the above technical deficiencies, an object of the present invention is to provide a block chain based CA-and-Key-removed electronic signature and electronic contract system, which utilizes a block chain technology to replace a CA certificate and a Key (shield) technology, so as to greatly reduce the subscription cost, improve the user experience, improve the subscription security, provide strong endorsement for electronic signatures and electronic subscriptions, improve the utilization rate of existing assets, and improve the adaptability, compatibility, flexibility and customer radiation range of subscriptions.
In order to solve the technical problems, the invention adopts the following technical scheme:
the CA and Key removal electronic signature and electronic contract system based on the block chain comprises a block chain based decentralized electronic signature and electronic contract mode, wherein the block chain certificate replaces the existing CA certificate, and the cloud signature mode replaces the existing Key shield signature mode.
Preferably, the system ecologically provides 'a bottom layer block chain operating system and a public service interface which are mutually signed and verified across platforms are built between different electronic signature systems' for a third party electronic signature and an electronic contract system.
Preferably, the system provides a specialized 'third-party electronic signature and electronic contract certification storage block chain' which is non-falsifiable and has judicial testification effect for the third-party electronic signature and electronic contract system ecology and is used for storing a digital certificate, a trace of electronic signature behavior (signature stamp) and an electronic contract hash value.
The invention has the beneficial effects that:
1. the signature system based on the block chain CA and Key saves the expense of CA centralization and mediation, the expense of Key and the maintenance cost of the center and the mediation;
2. distributed storage after decentralization, a consensus mechanism and cross authentication greatly improve the difficulty of breaking and tampering, and signature and contract data are not easy to tamper and divulge;
3. a decentralized signature and contract management system without the risk of single point collapse; the risk is low due to high system fault tolerance;
4. the signature and contract management system is decentralized, so that the independent interruption of the center, the hidden box operation and the maximization of the center benefit are avoided, and the corruption in CA, signature and contract management is avoided; the problem of a supervision supervisor is solved by mutual supervision;
5. the decentralization and the mediation reduce the complexity of the system without additional burden;
6. the flexibility is high due to high fault tolerance of the system, and the flexibility of the system is increased by decentralization.
