摘要: 针对如何构造一个在标准模型下高效的选择密文安全的单向代理重加密方案这个问题,提出了一种新的、高效的单向代理重加密方案,并且在标准模型下证明了方案在自适应攻陷模型下的选择密文安全性。所提方案与LV方案相比,在安全性和效率方面都有所提升,与WJ方案相比,在同等安全条件下,运算效率有所提高。
Abstract: In order to construct an efficient and chosen-chiphertext secure unidirectional re-encryption scheme in the standard model, a novel and efficient unidirectional proxy re-encryption scheme was proposed, and its chosen-ciphertext security in the adaptive corruption model was proved in the standard model. Compared with LV scheme, this scheme has the advantages of both higher efficiency and stronger security. Under the same security level, this scheme has lower computational cost than that of WJ scheme.
