Attribute-based non-interactive key exchange

Science China Information Sciences, 2016
创新点 (1) 形式化定义了基于属性的非交互式密钥交换协议并给出了相应的安全模型; (2) 基于非一致输入混淆器 (differing-input obfuscation, diO) 构造了一个具体的基于属性的非交互式密钥交换协议并证明其安全性; (3) 证明了基于属性的非交互式密钥交换协议这一概念蕴含了基于身份的非交互式密钥交换协议与多方基于属性的密钥交换协议。

Universally Composable Non-Interactive Key Exchange

2014
We consider the notion of a non-interactive key exchange (NIKE). A NIKE scheme allows a party A to compute a common shared key with another party B from B’s public key and A’s secret key alone. This computation requires no interaction between A and B, a feature which distinguishes NIKE from regular (i.e., interactive) key exchange not only ...

Non-Interactive Key Exchange from Identity-Based Encryption

Proceedings of the 13th International Conference on Availability, Reliability and Security, 2018
Since the seminal work of Diffie and Hellman [19], Non-Interactive Key Exchange (NIKE) has become one of the fundamental problems of modern cryptography, but additional security requirements have led to elaborated ad-hoc constructions, which often lack simplicity in their design.

Sakai–Ohgishi–Kasahara identity-based non-interactive key exchange revisited and more

International Journal of Information Security, 2015
Identity-based non-interactive key exchange (IB-NIKE) is a powerful but a bit overlooked primitive in identity-based cryptography. While identity-based encryption and signature have been extensively investigated over the past three decades, IB-NIKE has remained largely unstudied. So far, there are only few IB-NIKE schemes in the literature. Among them,

Fine-grained non-interactive key-exchange protocols

In this thesis, we initiate a study of K-NIKE protocols in the fine-grained setting, in which there is a polynomial gap between the running time of the honest parties and that of the adversary. Our goal is to show the possibility of basing such protocols on weaker assumptions than those of K-NIKE for K ≥ 3 of previous works.
