Salted hashes for message authentication - proof of concept on tiny embedded systems
2014 IEEE Symposium on Intelligent Embedded Systems (IES), 2014Intelligent embedded systems become more and more widespread. Especially in the field of smart environments, such as smart homes, the systems are communicating with each other. If wireless communication is used, security becomes important. This paper explores to what extent salted hashes might be used on tiny embedded systems to provide message ...

Novel Leakage-Resilient Attribute-Based Encryption from Hash Proof System
The Computer Journal, 2016As 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
2012We 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 ...

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
2018An 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.

Node attributes such as MAC and IP addresses, and even GPS position, can be considered as exclusive identity in the distributed networks such as cloud computing platform, wireless body area networks, and Internet of Things. Nodes can exchange or transmit some important information in the networks.

Strong Leakage and Tamper-Resilient PKE from Refined Hash Proof System
2019We revisit the problem of constructing public key encryption (PKE) secure against both key-leakage and tampering attacks. First, we present an enhanced security against both kinds of attacks, namely strong leakage and tamper-resilient chosen-ciphertext (sLTR-CCA) security, which imposes only minimal restrictions on the adversary’s queries and thus ...
