Description
Technical field
The present invention relates to field of quantum secure communication, more particularly, to a kind of privately owned block chain based on quantum cryptography watermark
Honest entity authentication cut-in method.
Background technique
Block chain is a kind of decentralization, can not distort, believable distributed account book, it provides a set of safety, steady
Mode that is fixed, transparent, can auditing and efficiently record transaction and data information interaction, can store data, can also run
Application program.Block chain technology is mainly used in existence proof, intelligent contract, Internet of Things, authentication, prediction city at present
The fields such as field, transaction in assets, file storage.
Its characteristics are as follows：
1) distributed account book that is highly safe, can not distorting.
2) it is present in internet, is disclosed to all users.
3) it helps to realize point-to-point transaction and exchange between person to person, object and object.
4) exchange of value can be completed without third-party intervention.
And there are mainly three types of the forms of block chain：Publicly-owned chain, alliance's chain, privately owned chain.
1) publicly-owned chain：Anyone can read block chain information, send and trade and can be identified, participate in the area of common recognition process
Block chain.
2) alliance's chain：It can be participated in, be traded according to node set by certain feature, common recognition process is controlled by preselected node
Block chain, though the scope of privately owned chain is actually still fallen between publicly-owned chain and privately owned chain.
3) privately owned chain：Permission is written only in a tissue hand, reading permission may confined block chain.To company
The settlement of transactions in audit testing and banking institution inside government has very big value.
It opens, with complete without permitting necessary publicly-owned chain different, alliance's chain and privately owned chain are at information extent of disclosure and center
It is limited in terms of control, these limitations can help block chain to meet different types of application demand.But with model
The safety of the diminution enclosed, privately owned chain inevitably falls under suspicion, even if the security of system guaranteed with common recognition mechanism
It is more credible, but privately owned chain lesser for range still has such as 51% attack hidden danger in common recognition mechanism.Wherein 51% attack
It hits after referring to that some client or tissue have grasped the 51% calculation power of block chain the whole network, calculates power with these to recalculate
The block of confirmed mistake, the behavior for making block chain generate bifurcated and acquiring an advantage.
Since privately owned chain still maintains the characteristic of block chain authenticity and part decentralization, need on this basis
The system that access privilege control is more stringent, and modification even reading permission is only limitted to a few users is createed, is allowed to have concurrently
The characteristics of centralization and centralization.Need design authority setting and mechanism of permitting the entrance, the node to ensure block chain substantially harmless simultaneously.
Thus while privately owned chain, which has, to have a extensive future, learns wildly from other's strong points, reducing the advantages such as threat, flexible compared to publicly-owned chain,
But also simultaneously because comparing that closing, innovation ability are open to suspicion, and there are trust problems.
The information security of Technique on Quantum Communication is based on quantum cryptology, breaches conventional cryptography using quantum state as key
The constraint of method, have can not eavesdrop, non-reproduction and theoretic " Unconditional security ".Any intercepting and capturing or test quantum
The operation of key, can all change quantum state, and quantum communications can ensure that encryption key distribution is perfectly safe with what is communicated between two places
Property.
