摘要： 通过对以往门限解密机制的研究，在Boneh和Boyen工作的基础上，提出了一个在标准模型下可证安全的基于身份的门限解密机制。并在解决判定性（t，q，ε）-BDHI困难问题假设基础上，证明此机制在标准模型下是指定身份适应性选择密文安全的。

Abstract: This paper presents an ID-based threshold decryption scheme based on works of Boneh and Boyen，which can be proved to be secure without random oracles.It is validated that it has ID-based adaptive chosen ciphertext security on solving decisional （t，q，ε）-BDHI problem assumption.
Key words: provable security, ID based cryptography, threshold decryption
