Lattice-based signcryption with equality test in standard model
Huy Quoc Le,Huy Quoc Le,Dung Hoang Duong,Partha Sarathi Roy,Willy Susilo,Kazuhide Fukushima,Shinsaku Kiyomoto +6 more
TL;DR: The first lattice-based signcryption scheme equipped with a solution to testing the message equality in the standard model was proposed in this article. But the proposed scheme is proven to be secure against insider attacks under the learning with errors assumption and the intractability of the short integer solution problem.

Towards Outsourced Privacy-Preserving Multiparty DBSCAN
Mohammad Shahriar Rahman,Anirban Basu,Shinsaku Kiyomoto +2 more
- 01 Jan 2017
TL;DR: This fast abstract shows how to outsource the DBSCAN computation on encrypted data to a cloud service provider securely such that the parties do not need to perform the expensive clustering computation locally.

Fault Injection Attack on Salsa20 and ChaCha and a Lightweight Countermeasure
Kazuhide Fukushima,Rui Xu,Shinsaku Kiyomoto,Naofumi Homma +3 more
- 01 Aug 2017
TL;DR: This work proposes a fault injection attack on Salsa20 and ChaCha stream ciphers that skips the corresponding addition (add) instruction to obtain the matrix X or X(20) and extracts the key and demonstrates an algorithm-specific but extremely lightweight countermeasure with less than 0.5% execution time overhead.

Portable Implementation of Lattice-Based Cryptography Using JavaScript
Ye Yuan,Chen-Mou Cheng,Shinsaku Kiyomoto,Yutaka Miyake,Tsuyoshi Takagi +4 more

TL;DR: The results demonstrate that some of today's Lattice-based cryptosystems can already have efficient JavaScript implementations and hence are ready for use on a growing list of JavaScript-enabled computing platforms.
Analysis of Program Obfuscation Schemes with Variable Encoding Technique
TL;DR: This paper analyzes obfuscation schemes and shows that the XOR-encoding scheme is superior, more clearly defining five types of attack models that were defined previously, and defining quantitative resistance to these attacks.
