Abstract
To address the requirements for secure,accurate,and efficient ciphertext data sharing and searching in cloud storage environments for enterprise data backup and cloud file sharing,a searchable encryption system supporting ciphertext index sharing is proposed based on bilinear mapping.Dy-namic data updates are achieved through a counter mechanism,while ciphertext index conversion is implemented via re-encryption techniques.Fine-grained file sharing is enabled for data owners through sharing tokens,and keyword searches can be executed by data users using their private keys.The scheme's security is proven under the Decisional Bilinear Diffie-Hellman(DBDH)assumption,accom-panied by a comprehensive complexity analysis.This solution ensures forward security while enabling fine-grained ciphertext sharing and searching capabilities.关键词
