Verifiable Encrypted Timed Signature Scheme and Its Application in Blockchains

Yuan Li, Junzuo Lai, Yi Liu, Liang Zhang et autres

Verifiable Timed Signatures (CCS '20) add a verification feature to timed signatures. Before spending computing effort, a solver can check that the timed signature contains a valid signature. Because of this, VTS has been used in distributed protocols such as atomic swaps …

Rethinking RSSI for WiFi sensing

Zhili Wang, J Junyi Zhang, Kai Wu, Y. Jay Guo

The Received Signal Strength Indicator (RSSI) is available on WiFi devices, yet it is often regarded as too coarse for sensing. This work revisits its sensing potential and presents WiRSSI, a bistatic framework for RSSI-only passive tracking and motion sensing. Moving beyond …

Tackling Arbitrarily Heterogeneous Data in Asynchronous Stochastic Gradient Descent Without Worker Scheduling

Xiaolu Wang, Yuchang Sun, Hoi-To Wai, J Junyi Zhang

We consider the distributed optimization problem with data dispersed across multiple workers under the orchestration of a parameter server. In distributed environments, variations in computation speeds and network conditions across workers often lead to significant idle times in synchronous training. Although asynchronous …

Iodine-mediated proton-coupled electron transfer enables selective polymerization of organic pollutants in an oxidant-free electrocatalytic system

Zexiao Zheng, J Junyi Zhang, Jonathan J. Calvillo Solís, Howard Y.M. Cheung et autres

Organic polymerization offers a sustainable water treatment approach that enables resource recovery, yet current oxidant-involved practices suffer from poor selectivity. We present an oxidant-free electrocatalytic system for phenolic pollutant polymerization via iodine-mediated proton-coupled electron transfer (PCET) with an iodine-enriched bismuth-oxyiodide-coated carbon cloth …

Estimation Errors as Regret Lower Bounds for Linear Contextual Bandits

Jiahao He, J Junyi Zhang, Rui Zhang

Linear contextual bandits and their variants represent a fundamental class of models with wide real-world applications, usually solved using algorithms guided by parameter estimation. The Cauchy-Schwarz inequality established analytically that estimation errors dominate algorithm regrets. Therefore, accurate parameter estimation suffices to guarantee …

Federated LoRA Fine-Tuning of LLMs With Only Transmitting Matrix A or B

Yiming Chen, Ruanjun Li, Jiawei Shao, Lifeng Sun et autres

Recent advancements in large language models (LLMs) have been largely driven by vast amounts of training data. As public data are exhausted, fine-tuning LLMs with private data has become increasingly important. However, due to privacy concerns associated with sensitive data, traditional centralized …
