Attribute-based Encryption Privacy Protection Model for Decentralized Key Management
摘要
Abstract
A decentralized key management and outsourced decryption privacy protection model for attribute-based encryption was proposed.Issues such as insecure centralized key management,heavy decryption computation burden on users,and inability to trace mali-cious users in traditional attribute-based encryption were addressed.The model combined attribute-based encryption and symmetric encryption to achieve fine-grained access control over data.Decryption operations were outsourced by leveraging computing nodes in the blockchain network,and the decryption computation burden on users was reduced.Secure multi-party computation technology was used to enable collaborative key generation and management.The blockchain public ledger was introduced to monitor and record user ac-tivities within the system,enabling full accountability in access control.Experimental re-sult verifies that the scheme can protect user security and privacy while enabling secure da-ta sharing.关键词
