摘要
为了提高边云协同模式下数据交互的安全性、效率性,提出了一种基于国密SM9的边云协同属性基签密方案.该方案将国密SM9算法和属性基签密算法相融合,利用线性秘密共享方案构造混合密钥与密文策略的访问控制机制,并借助边缘云协同网络实现方案部分外包解密.实验分析结果表明,该方案在提供灵活访问控制的同时,实现了边云协同模式下高效、可靠的安全防护,适用于需求动态、复杂的云应用场景.
In order to improve the security and efficiency of data interaction in edge cloud collaborative mode,an edge cloud collaborative attribute-based signcryption scheme based on state secret SM9 is proposed.This scheme integrates the state secret SM9 algorithm with attribute-based signcryption algorithm,constructs a mixed key and ciphertext policy access control mechanism with a linear secret sharing scheme,and implements partial outsourcing decryption through an edge cloud collaborative network.The experimental analysis results demonstrate that the proposed scheme provides flexible access control while achieving efficient and reliable security protection in the edge cloud collaborative mode,making it suitable for dynamic and complex cloud application scenarios.
