为了满足实际应用的需要,人们提出了许多不需要配对的无证书加密方案。最近,Lai等人提出了一个没有配对的CLE方案,并证明了他们的方案在随机预言模型下是可证安全的。分析表明,该方案比相关方案具有更好的性能。然而,Lai et al.的方案不是标准的CLE方案,因为在生成用户的部分私钥时使用了用户的公钥。在这项研究中,作者提出了一个新的CLE计划。与Lai et al.的格式,作者的格式是一个标准的CLE格式,但代价是计算量略有增加。此外,他们的计划有更好的性能比相关的计划,除了赖等人。的方案。他们还证明了他们的方案在随机预言模型下是可证明安全的。
To satisfy the requirement of practical applications, many certificateless encryption schemes (CLE) without pairing have been proposed. Recently, Lai et al. proposed a CLE scheme without pairing and demonstrated that their scheme is provably secure in the random oracle model. The analysis shows that their scheme has better performance than the related schemes. However, Lai et al.’s scheme is not a standard CLE scheme since the user's public key is used when generating his partial private key. In this study, the authors propose a new CLE scheme. Compared with Lai et al.’s scheme, the authors' scheme is a standard CLE scheme at the cost of increasing the computational cost slightly. Besides, their scheme has better performance than the related schemes except Lai et al.’s scheme. They also show their scheme is provably secure in the random oracle model.
