摘要

随着计算机技术的发展，现代网络攻防形势日益严峻，秘密信息的安全传输问题亟待解决。隐蔽通信技术将秘密信息嵌入载体中通过隐蔽信道安全地传输，但传统的隐蔽信道存在数据易受损、易被攻击、易被检测等问题，无法满足更高的安全需求。区块链作为公共数据平台，能够在大量交易的掩盖下嵌入秘密信息，其具有的不易篡改、匿名性、去中心化等特点，可以很好地解决传统隐蔽信道存在的问题，实现安全的隐蔽通信，但现有的区块链隐蔽通信方案存在通信效率较低、安全性较差等问题，如何安全、高效地进行通信是区块链隐蔽通信的研究重点。提出一种基于正常交易掩盖下的区块链隐蔽通信方案，利用哈希算法构建免传输密码表在不改变任何交易数据的情况下实现秘密信息的嵌入，利用椭圆曲线特性可在海量的交易中快速筛选出带有隐藏信息的交易，从而快速提取秘密信息。所提方案提高了隐蔽通信的安全性、效率，可迁移性强，理论分析显示，攻击者无法区分普通交易和特殊交易，所提方案具有极高的抗检测性和可扩展性；比特币测试网的实验结果表明，所提方案的效率高。

Abstract

With the development of computer technology

the situation of modern network attack and defense is becoming increasingly severe

and the problem of secure transmission of secret information needs to be solved urgently.Covert communication technology embeds secret information into the carrier and transmits the information safely through the covert channel.However

the traditional covert channels face the challenges of data damaging

attack

detection and so on

which cannot meet the higher security requirements.As a public data platform

blockchain can embed secret information under the cover of a large number of transactions.With its tamper proof

anonymity

decentralization and other characteristics

blockchain can well solve the problems of traditional covert channels and achieve secure covert communication.However

the existing blockchain covert communication schemes are limited by low communication efficiency and poor security.How to improve safety and efficiency of covert communication is a research focus of blockchain covert communication.Motivated by this issue

a blockchain covert communication scheme based on the cover of normal transactions was proposed.The hash algorithm was used to build a transmission-free password table to embed secret information without changing any transaction data.Using the elliptic curve feature

transactions with hidden information can be quickly screened out from a large number of transactions

to extract secret information quickly.This scheme improves the security and efficiency of covert communication and has strong portability.Theoretical analysis shows that attackers cannot distinguish between ordinary transactions and special transactions.This scheme has high anti-detection and scalability.Besides

the experimental results of the bitcoin test network show the high efficiency of this scheme.
