一种基于比特币的"一对多"隐蔽通信方法
A Bitcoin-Based One-to-Many Covert Communication Method
摘要
Abstract
Aiming at the problem that existing covert communication studies based on cryptocurrency systems are restricted to the one-to-one scenario and rely on pre-shared keys,a one-to-many covert communication method based on Bitcoin is proposed by introducing the concept of public-key broad-cast encryption.The ciphertext and the broadcast encryption information sequence carrying the cipher-text encryption key are respectively disguised and embedded into the output amounts and output ad-dresses of special Bitcoin transactions.Without sending multiple message copies,precise one-to-many covert information broadcasting within a specified group is achieved,and different receivers can be designated for each communication after system initialization.Special transactions containing covert in-formation are identified by decryption correctness,which can prevent information access by internal malicious entities.The proposed scheme is verified on the Bitcoin testnet.The results demonstrate that the method can realize covert information broadcasting among different receivers without pre-negoti-ated session keys.关键词
