可扩展且支持多种追踪机制的属性基加密方案
Scalable attribute-based encryption scheme with multiple tracing mechanisms
摘要
Abstract
To solve the problem of a single malicious user tracing mechanism in attribute-based encryption(ABE)schemes,a scalable ABE scheme with multiple tracing mechanisms was proposed.Firstly,white-box traceability was implemented using short signatures,and black-box traceability was achieved by embedding user information in secret key and constructing tracing ciphertexts,thereby providing a comprehensive capability for tracing malicious users.Sec-ondly,a system initialization mechanism independent of the attribute universe was designed,which supports dynamic at-tribute expansion without system reset,effectively fulfilling the dynamic expansion requirements of encryption systems in large attribute universes.Finally,security analysis demonstrated that the proposed scheme exhibits ciphertext indistin-guishability under chosen-plaintext attacks,white-box traceability,and black-box traceability.Performance analysis veri-fied its feasibility.关键词
