The RIS-ODA leverages partial Channel State Information (CSI) to simultaneously enhance eavesdropping rate and degrade the legitimate receiver’s communication rate. The attack strategy is formulated as a dual-objective optimization problem, which is solved using triangle inequality and Bernstein-Type Inequality (BTI) to handle probability measure constraints. Simulation results demonstrate that the proposed method effectively enhances eavesdropping rate and suppresses Bob’s communication rate without requiring perfect CSI or additional power, achieving a superior balance between attack performance and practical implementation feasibility.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 9","pages":"2198-2202"},"PeriodicalIF":4.4,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents a novel authentication scheme designed to enhance security in 5G downlink positioning using the positioning reference signal (PRS). The proposed method embeds a hash-based message authentication code (HMAC) of the PRS into the empty resource elements (REs) of its comb-based structure, along with the original PRS sequence. Furthermore, a novel authentication similarity threshold is introduced, enabling the HMAC authentication process to operate under lower SNR conditions. In addition, the proposed method in the presence of channel estimation, synchronization and carrier frequency offset errors is quantified, reporting the percentage of erroneous bits in each extracted HMAC sequence. The robustness of the proposed threshold mechanism is highlighted, demonstrating its ability to tolerate bit errors caused by impairments of the physical layer. Simulations reveal that occupation of these REs does not affect position estimation.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 9","pages":"2188-2192"},"PeriodicalIF":4.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11084864","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this letter, we propose clustered subcarrier structure to implement illegal sensing suppression (ISS) in orthogonal frequency division multiplexing (OFDM) systems. Specifically, following the ambiguity function (AF), the proposed clustered structure exploits removable singularities in its AF to generate virtual interference, thereby deteriorating the illegal detection. The optimal parameters are further derived by minimizing proposed peak-to-virtual-interference ratio (PVIR), and the subcarrier-ISS trade-off is investigated between the number of data subcarriers and ISS capacity. Simulation results demonstrate the superior ISS of proposed approach compared to other baselines.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 9","pages":"2183-2187"},"PeriodicalIF":4.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing IRSA schemes for the BAC, which rely on dense Bernoulli matrices as codebooks, struggle to resolve a large number of collisions, primarily due to the high density of the codebook. To address it, we introduce a codebook construction using sparse random combinatorial matrices, where each codeword is a binary vector with exactly d ones, optimized to maximize the collision resolution capabilities. Furthermore, the proposed scheme eliminates pilot symbols by leveraging the codebook’s inherent sparsity and combinatorial structure. Numerical simulations show that the proposed scheme achieves a higher decoding threshold and superior average sum rate compared to existing schemes, thanks to its enhanced collision resolution capabilities.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 9","pages":"2193-2197"},"PeriodicalIF":4.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motivated by this, we consider the sum sensing rate (SR) optimization for a cooperative ISAC system with linear precoding, where each base station (BS) works in a different frequency band. With this aim, we propose an optimization algorithm based on the semi-definite rank relaxation that introduces covariance matrices as optimization variables, and we apply the inner approximation (IA) method to deal with the nonconvexity of the resulting problem. Simulation results show that the proposed algorithm increases the SR by approximately 25% and 40% compared to the case of equal power distribution in a cooperative ISAC system with two and three BSs, respectively. Additionally, the algorithm converges in only a few iterations, while its most beneficial implementation scenario is in the low power regime.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 9","pages":"2163-2167"},"PeriodicalIF":4.4,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
