Novel Leakage-Resilient Attribute-Based Encryption from Hash Proof System

The Computer Journal, 2016
As an important primitive, attribute-based encryption (ABE) has attracted much attention in the relative-leakage model. However, the leakage rate in almost all of the existing ABE schemes is restricted with a leakage parameter. It implicitly suggests that higher leakage rate results in larger ciphertexts and keys.

Anonymous Identity-Based Hash Proof System and Its Applications

2012
We introduce the concept of anonymous identity-based hash proof system (IB-HPS), and show how to use it to construct identity-based encryption schemes providing anonymity in the presence of key leakage. We give four different constructions of anonymous IB-HPS based on: (1) the decision bilinear Diffie-Hellman assumption, (2) the decision truncated ...

Revisiting post-quantum hash proof systems over lattices for Internet of Thing authentications

Journal of Ambient Intelligence and Humanized Computing, 2019
Internet of Things (IoT) has proved to be one of a success subset of cyber-physical systems, and it is receiving much attention among end-users associated with various applications. However, with the popularization of the IoT technologies, network attacks on the IoT environment are also increasing.

Novel Identity-Based Hash Proof System with Compact Master Public Key from Lattices in the Standard Model

International Journal of Foundations of Computer Science, 2019
As the progress of quantum computers, it is desired to propose many more efficient cryptographic constructions with post-quantum security. In the literatures, almost all cryptographic schemes and protocols can be explained and constructed modularly from certain cryptographic primitives, among which an Identity-Based Hash Proof System (IB-HPS) is one ...

Anonymous Identity-Based Hash Proof System from Lattices in the Standard Model

2018
An Identity-Based Hash Proof System (IB-HPS) is a fundamental and important primitive, which is widely adapted to construct a number of cryptographic schemes and protocols, especially for leakage-resilient ones. Therefore it is significant to instantiate IB-HPSs from various assumptions.
