An Efficient Identity-Based Key Agreement Protocol in a Multiple PKG Environment

Zhou Zhou, Huan, Wang +3 more

基于身份的关键协议协议负担得起一个自然方法把参加者身份与它的公钥相结合。然而，他们中的大多数就在一个单个私人关键发电机(PKG ) 考虑关键协议环境。另外，存在关键协议协议为今天越来越流行的移动计算有大计算开销。这份报纸建议新身份基于关键协议协议。在数学工具的帮助下，我们使我们的协议在多重 PKG 环境应用了。它也满足被放为关键协议协议的所有安全性质。而且，一些它的费时间的操作能被送到 untrusted 公众计算资源，它的计算复杂性能极大地因此被减少。基于身份的关键协议协议负担得起一个自然方法把参加者身份与它的公钥相结合。然而，他们中的大多数就在一个单个私人关键发电机(PKG ) 考虑关键协议环境。另外，存在关键协议协议为今天越来越流行的移动计算有大计算开销。这份报纸建议新身份基于关键协议协议。在数学工具的帮助下，我们使我们的协议在多重 PKG 环境应用了。它也满足被放为关键协议协议的所有安全性质。而且，一些它的费时间的操作能被送到 untrusted 公众计算资源，它的计算复杂性能极大地因此被减少。

Provably Secure Identity-based Authenticated Key Agreement Protocols in Multiple PKG Environment

Song Xia, Jian-xiao Quan, Wenbao Han

摘要: 目前大多数基于身份认证密钥协商协议需要参与协议双方在同一个PKG环境下，而实际应用中需要在不同PKG环境下的用户之间也能进行安全通信。该文结合twin Diffie-Hellman问题提出了一个全新的不同PKG环境下的基于身份认证密钥协商协议。利用Cash等人在2008年欧密会上提出的trapdoor test技术在eCK模型中将新协议的安全性规约到标准的CDH和BDH 假设。关键词: 密码学 / 认证密钥协商 / 基于身份 / 双线性对 / 不同PKG环境 / Trapdoor test技术摘要: 目前大多数基于身份认证密钥协商协议需要参与协议双方在同一个PKG环境下，而实际应用中需要在不同PKG环境下的用户之间也能进行安全通信。该文结合twin Diffie-Hellman问题提出了一个全新的不同PKG环境下的基于身份认证密钥协商协议。利用Cash等人在2008年欧密会上提出的trapdoor test技术在eCK模型中将新协议的安全性规约到标准的CDH和BDH 假设。关键词: 密码学 / 认证密钥协商 / 基于身份 / 双线性对 / 不同PKG环境 / Trapdoor test技术

Identity based group key agreement in multiple PKG environment

Wang Liming, Wu Chuankun

Secure and reliable group communication is an increasingly active research area by growing popularity in group-oriented and collaborative applications. In this paper, we propose the first identity-based authenticated group key agreement in multiple private key generators (PKG) environment. It is inspired on a new two-party identity-based key agreement protocol first proposed by Hoonjung Lee et al. In our scheme, although each member comes from different domain and belongs to different PKGs which do not share the common system parameters, they can agree on a shared secret group key. We show that our scheme satisfies every security requirements of the group key agreement protocols.Secure and reliable group communication is an increasingly active research area by growing popularity in group-oriented and collaborative applications.
