For secure communication in a distributed cooperation, generally, the data are encrypted and decrypted using a symmetric key. The process of creating, distributing, storing, deploying, and finally revoking the cryptographic keys is called key management. On the basis of the structure, usability, and complexity of the cyber-physical systems, each one of the current key management practices is suitable for a specific range of applications. However, these schemes have some drawbacks in common, such as complicated key generation and distribution process, using key storage, attacks, and traffic load. This paper proposes a key management model for establishing secure communications in the distributed industrial intelligent systems. The model is attack resistant, has high usability in real-world applications, and transforms the current customary key management workflow to enhance security and reduce weaknesses. Its main features include reduced process, intelligent attack resistance, producing dynamic keys with no additional cost, and eliminating key storage and revocation calls.

分布式工业智能系统安全通信的智能密钥管理模型

对于分布式协作中的安全通信，通常使用对称密钥对数据进行加密和解密。创建、分发、存储、部署和最终撤销加密密钥的过程称为密钥管理。基于信息物理系统的结构、可用性和复杂性，当前的每一种密钥管理实践都适用于特定的应用范围。然而，这些方案都存在一些共同的缺点，例如复杂的密钥生成和分发过程、使用密钥存储、攻击和流量负载。本文提出了一种在分布式工业智能系统中建立安全通信的密钥管理模型。该模型具有抗攻击性，在实际应用中具有高可用性，并改变当前惯用的密钥管理工作流程，以增强安全性并减少弱点。其主要特点包括减少流程、智能抗攻击、无需额外成本生成动态密钥、消除密钥存储和撤销调用。
