摘要:
针对现有区块链隐蔽通信方案普遍存在缺乏前向安全性、抗关联分析能力薄弱以及通信流程不完备等核心问题，提出一种自演进的闭环区块链隐蔽通信协议（SECL-CCP）。该协议通过三大创新机制构建了一个从密钥、协议流程到链上基础设施均能动态演进的安全体系。首先，设计“密钥棘轮”机制，结合“承诺-揭示”方案与区块链未来状态的公共熵，实现密钥的不可逆更新，赋予协议前向安全性。其次，提出“动态合约工厂”模型，利用CREATE2操作码为每轮通信动态部署“用完即弃”的交互合约，消除固定链上指纹。最后，引入基于零知识证明的接收回执机制，构建可验证的通信闭环，解决接收方不可抵赖问题。仿真实验基于以太坊Sepolia测试网与Hardhat环境开展，采集主网真实流量构建了含20,000条样本的混合数据集。结果表明，该协议将随机森林与LSTM模型下的隐写分析检测率分别降至12.8%与11.5%，并在密钥泄露场景下实现历史信息零泄露，有效抵御了智能关联分析攻击。
Abstract:
To address the core problems of lacking forward secrecy, weak anti-correlation analysis capabilities, and incomplete communication processes universally existing in current blockchain covert communication schemes, a self-evolving closed-loop covert communication protocol (SECL-CCP) was proposed. Through three innovative mechanisms, a security architecture capable of dynamic evolution across keys, protocol processes, and on-chain infrastructure was constructed. First, a "key ratchet" mechanism was designed, wherein the "commit-reveal" scheme was combined with the public entropy of blockchain future states, irreversible key updates were realized, and forward secrecy was endowed to the protocol. Secondly, a "dynamic contract factory" model was proposed, and the CREATE2 opcode was utilized to dynamically deploy disposable interactive contracts for each communication round, whereby fixed on-chain fingerprints were eliminated. Finally, a receipt mechanism based on zero-knowledge proof was introduced to build a verifiable communication closed loop, and the receiver non-repudiation problem was resolved. Simulation experiments were conducted based on the Ethereum Sepolia testnet and Hardhat environment, and a mixed dataset containing 20,000 samples was constructed by collecting real mainnet traffic. It was demonstrated by the results that the steganalysis detection rates under random forest and LSTM models were respectively reduced to 12.8% and 11.5%, zero leakage of historical information under key compromise scenarios was achieved, and intelligent correlation analysis attacks were effectively resisted
