Embodiment

[0040] Such as figure 1 As shown, a blockchain concealed data segment transmission method includes the following steps:

[0041] Step 1: Pre-negotiate the key. The sender and the receiver negotiate in advance the screening method of the special transaction, the key used to encrypt the hidden information and the relevant parameters of the hidden information segment.

[0042] Specifically, the sender and the receiver pre-negotiate the encrypted one-time key K, and the number of segments negotiated in advance between the sender and the receiver is n. Such as figure 2 shown.

[0043] In this embodiment, a secure symmetric key cryptosystem SKE is used to encrypt segmented covert messages, and the SKE scheme includes an encryption algorithm Enc and a decryption algorithm Dec, wherein:

[0044] Encryption algorithm: c←Enc(K,m), means to receive a key K and a hidden information m as input, and output a ciphertext c.

[0045] Decryption algorithm: m←Dec(K,c), means to receive a k...

Abstract

The invention relates to a block chain hidden data segment transmission method, and belongs to the technical field of data hidden transmission. According to the method, text data are segmented, and the segmented data are stored in self-defined data segments of block chain transactions. A block chain platform is used for implementing hidden information transmission, and due to a broadcast mechanism of a block chain, a sender does not need to directly establish connection with a receiver, so that addresses of two communication parties are not exposed, and anonymity of the two communication parties is realized to a certain extent. The hidden information is stored by using the custom data field in the block chain, the hidden data of the text is segmented, and the hidden information is transmitted through multiple block chain transactions, so that block chain-based text hidden data transmission is realized. The method is high in anonymity and practicability, and can be used for various block chain networks.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a block chain concealed data segmentation transmission method, and belongs to the technical field of data concealed transmission. [0002] technical background [0003] With the development of computer networks, more and more people and companies use the Internet to communicate. During the communication process, information containing personal information and even commercial secrets is transmitted on network channels, which brings security and privacy issues. Therefore, more and more privacy protection technologies based on cryptographic primitives have been proposed to ensure the confidentiality and integrity of user privacy information during communication. In these confidential communication scenarios, both the transmitted content and the communication act itself should be protected. [0004] In order to hide the communication behavior on the Internet, on the basis of traditional...
