摘要:

针对传统的区块链数据隐蔽传输方案存在隐蔽性差、信道容量低、时间成本高的问题,设计了一种将数据嵌入机制和交易筛选机制分离的新模型,提出了一种基于地址动态标签的交易筛选算法。该方案利用密钥相关的哈希运算消息认证码构造携带标签信息的特殊地址,使接收方能够高效隐蔽地从区块链账本海量数据中筛选出携带隐蔽信息的特殊交易,实现在开放式区块链环境下的数据隐蔽传输。仿真结果表明,所提方案能够在比特币真实网络中实现数据隐蔽传输。方案的隐蔽性和效率优于传统方案,具有较强的实用性。

Abstract:

The existing blockchain data covert transmission scheme is faced with the problems of poor concealment, small channel capacity and low efficiency. This paper designs a new model for separating the data embedding mechanism from the transaction filtering mechanism, and proposes a new filtering algorithm based on the address dynamic label. In this scheme,the HMAC algorithm is used to construct the special address label, so that the receiving party can effectively screen the special transaction carrying the concealed information from the massive data in the blockchain ledger, and realize the concealed data transmission in the open blockchain scenario. Simulation results show that the proposed scheme can realize the hidden transmission of data in the real bitcoin network. The concealment and efficiency of the scheme are better than those of the traditional scheme.

Key words: blockchain, information hiding, hash-based message authentication code, dynamic labels, steganography
