中文摘要：

我们建议新生物测定的身份基于加密计划(Bio-IBE ) ，在哪个用户生物测定的信息被用来与一个模糊抽出者产生公钥。这是完成经常的尺寸密文的第一个 Bio-IBE 计划。这也是对适应选择密文攻击(CCA2 ) 是安全的一个计划。细节与 Shamirs 阀值秘密分享和生物测定学的模糊抽取的讨论一起被介绍，它基于错误修正代码。我们也定义一个安全模型并且证明建议计划的安全被归结为 decisional 双线性的 Diffie-Hellman (DBDH ) 假设。比较证明建议计划与可得到的 Bio-IBE 计划相比有更好的效率和更强壮的安全。

英文摘要：

We propose a new biometric identity based encryption scheme （Bio-IBE）, in which user biometric information is used to generate the public key with a fuzzy extractor. This is the first Bio-IBE scheme that achieves constant size ciphertext. This is also a scheme that is secure against the adaptive chosen ciphertext attack （CCA2）. Details are presented along with a discussion of Shamir＇s threshold secret sharing and fuzzy extraction of biometrics, which is based on error correction codes. We also define a security model and prove that the security of the proposed scheme is reduced to the decisional bilinear Diffie-Hellman proposed scheme has better efficiency and stronger security （DBDH） assumption. The comparison shows that the compared with the available Bio-IBE schemes.
