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。
关键词: 可证安全, 基于身份加密, 门限解密
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
