Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without inventive exercise.
Fig. 1 is a flowchart of a block chain-based data concealment transmission method according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention aims to provide a block chain-based data covert transmission method, which protects the addresses of a sender and a receiver and transmission data through a zero-knowledge proof technology, further protects the data to be transmitted through disordered data, and completes the covert transmission of the data.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Regarding the data protection problem of the block chain, there are four main ways at present:
the realization idea of the coin mixing principle is to split the relationship between the input address and the output address. In a transaction, given the large number of people involved, including a large number of inputs and outputs, it is difficult to find each person's corresponding pair in the inputs and outputs, so that the connection between the inputs and outputs is effectively broken; the effect is better when coins are mixed for multiple times and a small amount of coins are used each time. Although this method is highly anonymous, its risk assessment is not in place and an anonymous third party must be trusted.
A ring signature is a simplified class group signature that is named because the signature consists of certain rules into a ring. In the ring signature scheme, one member in the ring signs with his private key and the public keys of the other members, but does not need to acquire the permission of the other members, and the verifier only knows that the signature comes from the ring, but does not know who is the true signer. The ring signature solves the problem of complete anonymity of a signer, allows a member to represent a group of people for signing without leaking the information of the signer, but the ring signature technology only solves the anonymity problem of a trader and cannot carry out privacy protection on trading contents.
Homomorphic encryption is a method which can execute calculation without decrypting encrypted data in advance, perfect balance can be achieved by storing data on a block chain by using homomorphic encryption technology, no significant change can be caused to block chain attributes, transaction finance and user balance on the block chain can be hidden by using addition homomorphic encryption technology, and the operation of balance on a public account by other users is ensured, but homomorphic encryption cannot confirm transaction consistency, and a verification link for transaction validity is lacked.
The zero knowledge proof is a kind of zero knowledge proof that proves some data operations without revealing the data itself, allowing both parties to prove that a proposal is genuine, and without revealing any information other than that it is genuine. By using the zero-knowledge proof mechanism, the addresses and transaction details of both transaction parties can be hidden.
