可证安全的基于身份条件代理重加密方案
Provably Secure Identity-based Conditional Proxy Re-encryption Scheme
摘要
Abstract
The conditional proxy re-encryption based on the traditional public key cryptosystem is mature,but the Identity-based Proxy Re-encryption (IBPRE) scheme,controlling agents' permissions from the fine-grained level is a problem needed to be solved.Thus,this paper proposes an identity-based conditional proxy re-encryption scheme.The security of the scheme is proven equivalent to the DBDH problem,and its chosen-ciphertext security in the adaptive corruption model is proved in the random oracle model.Security analysis results show that,compared with other schemes,this scheme has better security,practicality and higher efficiency.关键词
