本研究提出一种新型构造——博罗米恩纠缠变色龙陷门哈希全或无（AoNT）流密码（BEC-Trap），该构造将博罗米恩相互依存性、陷门支持的可变性与流加密融合为统一框架。BEC-Trap密码将密钥（K）、初始化向量（V）和内部状态（St）以博罗米恩结构关联，确保破解、猜测或移除任一组件都会使整个密钥流崩溃，在标准密码学假设下提供计算性AoNT相互依存性。研究中集成变色龙陷门哈希以允许受控碰撞，支持无需同步端点的无缝密钥更新、V刷新和状态旋转。该设计具备保密性、前向保密性和自适应密钥管理能力，计算开销低，适用于高吞吐量安全消息传输、物联网通信及隐私保护区块链通道。对BEC-Trap的安全性分析显示，该构造可抵御密钥恢复攻击、状态泄露及同步失败尝试，为下一代安全通信提供稳健的密码原语。
英文摘要
This work introduces the Borromean-Entangled Chameleon Trapdoor Hash All-or-Nothing (AoNT) Stream Cipher (BEC-Trap), a novel construction that merges Borromean interdependence, trapdoor-enabled mutability, and streaming encryption into a unified framework. The (BEC-Trap) cipher links key (K), initialization vector (V ), and internal state (St) in a Borromean structure, ensuring that breaking, guessing, or removing any one component collapses the entire keystream, providing a computational (AoNT) interdependence under standard cryptographic assumptions. A chameleon trapdoor hash is integrated to permit controlled collisions, enabling seamless rekeying, (V ) refresh, and state rotation without resynchronizing endpoints. This design provides confidentiality, forward secrecy, and adaptive key management with low computational overhead, making it suitable for high-throughput secure messaging, IoT communications, and privacy-preserving blockchain channels. Security analysis of the (BEC-Trap) shows that the construction is resistant to key-recovery attacks, state compromise, and desynchronization attempts, delivering a robust cryptographic primitive for next-generation secure communications.
