最近，Liu等人[26]发现无证书公钥加密（CL-PKE）遭受拒绝解密（DoD）攻击。基于CL-PKC，作者引入了一种称为自生成证书公钥密码学（SGC-PKC）的新范式，该范式捕获了DoD攻击，并提出了第一个方案，该方案源自Water基于身份的加密方案的新应用[43]。在本文中，我们提出了一个新的SGC-PKE方案，不依赖于双线性对，因此，是更有效的，需要更短的公钥比刘等人。的方案。更重要的是，我们的方案达到了Girault的信任级别3 [16]（参见。Girault的信任级别2和Au的方案），与传统PKI实现的信任级别相同。此外，我们还讨论了如何我们的计划可以导致一个安全的和自组织的密钥管理和认证系统的ad hoc无线网络与用户控制的密钥更新的功能。(C)2011 Elsevier Inc.

Recently, Liu et al. [26] discovered that Certificateless Public Key Encryption (CL-PKE) suffers the Denial-of-Decryption (DoD) attack. Based on CL-PKC, the authors introduced a new paradigm called Self-Generated-Certificate Public Key Cryptography (SGC-PKC) that captured the DoD attack and proposed the first scheme derived from a novel application of Water's Identity-Based Encryption scheme [43]. In this paper, we propose a new SGC-PKE scheme that does not depend on the bilinear pairings and hence, is more efficient and requires shorter public keys than Liu et al.'s scheme. More importantly, our scheme reaches Girault's trust level 3 [16] (cf. Girault's trust level 2 of Liu and Au's scheme), the same trust level achieved by a traditional PKI. In addition, we also discuss how our scheme can lead to a secure and self-organized key management and authentication system for ad hoc wireless networks with a function of user-controlled key renewal.
