| Keyword | 基于身份的加密系统 层次式基于身份的加密系统 选择密文安全 标准计算模型 |
| English Abstract | 本文提出了一些构造IBE（基于身份的加密）方案的新方法，解决了一些IBE领域的公开问题，例如构造在标准计算模型下（而不是在RANDOM ORACLE模型下）选择密文安全的工BE系统。另外，我们对Shair有关IBE的原始想法进行扩展：不仅使收信人身份的验证不需发信人的介入，也使发信人身份的验证不需收信人的介入。进一步，我们首次在IBE方案中增加了一些重要功能，例如对收信人和发信人身份的即时撤销。最后，我们提出了一个基于身份的可信任可扩展的健壮电子邮件系统，它比传统的电子邮件系统多了一些新功能，诸如：源地址认证，抵御垃圾邮件，和邮件内容有关的收信回执，收信人可获得发信凭证（和源地址，信内容有关），等等。另外，该系统易于扩展至层次式，扩展方法比已知的类似方法〔10，13〕容易。 |
| Abstract | We construct IBE schemes in some new ways, and solve some open problems in this field , such as building identity based systems that are chosen ciphertext security in the standard computation model rather than the random oracle model (proposed by [2]). In addition, we expand Shamir' s original idea of IBE system: we not only make authentication of Receiver' s identity without the involvement of the sender, but also make authentication of sender' s identity without the involvement of the Receiver. Furthermore, we realize, for the first time, some functions in IBE schemes, such as instant revoking of receiver' s identity and sender' s identity. At last we propose a trustworthy and hierarchical Email system based on our IBE, which adds many new functions to traditional Email system , such as authentication of Email' s source address, resisting junk Emails, receipt related to Email content , generating evidence of sending Email (related to source address, content of the Email), etc. Additionally, we can expand this system to a hierarchical system by a method simpler than all existing ones [10,13]. |
