-
摘要:
随着工业物联网(IoT)、云计算等信息技术与工业控制系统(ICS)的整合,工业数据的安全正面临着极大风险。为了能在这样一个复杂的分布式环境中保护数据的机密性和完整性,该文采用基于属性的加密(ABE)算法,设计一种集数据加密、访问控制、解密外包、数据验证为一体的通信方案,同时具有密文长度恒定的特点。最后,从正确性、安全性和性能开销3个方面对方案进行详细的分析,并通过仿真验证得出该算法具有低解密开销的优势。
Abstract:With the integration of information technology such as industrial Internet of Things (IoT), cloud computing and Industrial Control System (ICS), the security of industrial data is at enormous risk. In order to protect the confidentiality and integrity of data in such a complex distributed environment, a communication scheme is proposed based on Attribute-Based Encryption (ABE) algorithm, which integrates data encryption, access control, decryption outsourcing and data verification. In addition, it has the characteristics of constant ciphertext length. Finally, the scheme is analyzed in detail from three aspectsie correctness, security and performance overhead. The simulation results show that the algorithm has the advantage of low decryption overhead.
