Economic statistics are frequently produced at an administrative level such as the subnational division. However, these measures may lack sufficient local variation for effective analysis of local eco...
Monitoring vegetation dynamics in East Rennell Island World Heritage Site using multi-sensor and multi-temporal remote sensing data
East Rennell World Heritage Site (ERWHS) vegetation cover forest cover dynamic monitoring multi-sources remote sensing data
2024/1/19
East Rennell of Solomon Island is the first natural site under customary law to be inscribed on UNESCO's World Heritage List. Potential threats due to logging, mining and agriculture led to the site b...
Highly Efficient Key Exchange Protocols with Optimal Tightness -- Enabling real-world deployments with theoretically sound parameters
AKE provable security tightness
2019/6/24
In this paper we give nearly-tight reductions for modern implicitly authenticated Diffie-Hellman protocols in the style of the Signal and Noise protocols which are extremely simple and efficient. Unli...
Lattice-based Cryptography for IoT in A Quantum World: Are We Ready?
Quantum Safe cryptography Post quantum cryptography IoT security
2019/6/12
The impending realization of scalable quantum computers has led to active research in Post Quantum Cryptography (PQC). The challenge is harder for embedded IoT (edge) devices, due to their pervasive d...
Blockchain-based smart contract platforms like Ethereum have become quite popular as a way to remove trust and add transparency to distributed applications. While different types of important applicat...
Finding Collisions in a Quantum World: Quantum Black-Box Separation of Collision-Resistance and One-Wayness
post-quantum cryptography one-way permutation one-way trapdoor permutation
2018/11/12
Since the celebrated work of Impagliazzo and Rudich (STOC 1989), a number of black-box impossibility results have been established. However, these works only ruled out classical black-box reductions a...

Peace Works is two things: an impassioned argument on why the United States should involve itself in conflict prevention, management and peace-making; and an important contribution to the practitioner...
From Keys to Databases -- Real-World Applications of Secure Multi-Party Computation
Cryptography Protocols Multi-Party Computation
2018/5/22
We discuss the widely increasing range of applications of a cryptographic technique called Multi-Party Computation. For many decades this was perceived to be of purely theoretical interest, but now it...
Enforcing ideal-world leakage bounds in real-world secret sharing MPC frameworks
