As an alternative, link-signature-based (LSB) secret key extraction techniques have received many interests in recent years. It is believed that these mechanisms are secure, based on the fundamental assumption that wireless signals received at two locations separated by more than half a wavelength apart are uncorrelated. However, recently it has been observed that in some circumstances this assumption does not hold, rendering LSB key extraction mechanisms vulnerable to attacks. This paper studies empirical statistical inference attacks (SIA) to LSB key extraction, whereby an attacker infers the signature of a target link, and henceforce recovers the secret key extracted from that signature, by observing the surrounding links. Different from prior work that assumes a theoretical link-correlation model for the inference, our study does not make any assumption on link correlation. Instead, ours is taking a machine learning method for link inference based on empirically measured link data. Machine learning (ML) algorithms are developed to launch SIA under various realistic scenarios. Our experiment results show that even without making assumptions on link correlation, the proposed inference algorithms are still quite effective, and can reduce the key search space by many orders of magnitudes compared to brutal force search.","PeriodicalId":113767,"journal":{"name":"MILCOM 2017 - 2017 IEEE Military Communications Conference (MILCOM)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129433561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper also presents additional performance data collected from emulation-based mobile network experiments. EM is a low complexity extension to Simplified Multicast Forwarding (SMF) that adds group-specific dynamic pruning of the SMF-based multicast forwarding mesh for higher rate traffic flows. It therefore reduces overhead by pruning the SMF relay sets in areas where no receivers exist. Our experimental emulation results show that, under a variety of mobility conditions and multicast group distribution patterns, EM maintains SMF-like data delivery robustness while significantly reducing overhead. We also demonstrate that a new design feature that provides preemptive ACK messages for active receiver groups leads to lower loss under mobility and sparse receiver groups. Based upon the results, we consider this feature critical to be included in any future EM design. We also present experimental results examining the performance of EM with classical flooding (CF) and connected dominating set (CDS) relay modes. We show, for the experiments examined, that CF provides some reduced loss with minimal additional overhead when used with EM. We also discuss future work and ongoing issues.","PeriodicalId":113767,"journal":{"name":"MILCOM 2017 - 2017 IEEE Military Communications Conference (MILCOM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114313587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sounder operates in the frequency range from 3 GHz to 18 GHz thus providing a Fourier delay resolution of 66.7 ps. The developed sounder measures overlapping sub-bands of 1 GHz bandwidth to cover the whole frequency range. This allows us to use a waveform generator and a digitizer with relatively lower sample rates and significantly lowers the cost compared to sampling the whole band at once. With the transmit power of 40 dBm, the maximum measurable path loss is 132 dB without accounting possible antenna gains. In this work, we also describe the calibration procedure along with the method to patch sub-bands into a combined channel response. This approach is validated by comparing the results from vector network analyzer(VNA) measurements performed in the same static environment. In contrast to VNAs, however, our sounder is real-time and can measure in dynamic environments with maximum Doppler spreads up to 166.7 Hz. Additionally, we present sample results from the first measurement campaign performed in an urban cellular scenario covering 3–18 GHz.","PeriodicalId":113767,"journal":{"name":"MILCOM 2017 - 2017 IEEE Military Communications Conference (MILCOM)","volume":"471 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115922581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current practice is for an onboard ship router to select a particular SATCOM link for each outgoing traffic flow based on a mission-specific routing policy. In this paper we propose an alternative solution by viewing the multi-SATCOM link utilization task as a traffic engineering and load balancing problem — in particular, as a Multi-Commodity Flow (MCF) optimization problem. We propose using the Flow Deviation Method (FDM) as a network-wide optimal load-balancing solution that maximizes total throughput and minimizes traffic flow delay and jitter. Our approach is equally valid for both UDP and TCP flows. Network-wide global optimization is carried out via a central controller in a Software Defined Networking (SDN) framework. For TCP flows we propose a novel solution that combines the best attributes of Multi-Path TCP, SDN and FDM. Compared to single-path TCP or MPTCP-SDN without FDM-based traffic optimizer, our proposed combined scheme is more efficient in bandwidth utilization, delay/jitter minimization and also robust against jamming and intermittent link failure. Network performance results are validated via Mininet emulation tests.","PeriodicalId":113767,"journal":{"name":"MILCOM 2017 - 2017 IEEE Military Communications Conference (MILCOM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130279824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, Intel Security Labs reported that during the second quarter of 2016, their system found more than 40M of new malware [1]. The damage of malware attacks is also increasingly devastating, as witnessed by the recent Cryptowall malware that has reportedly generated more than $325M in ransom payments to its perpetrators [2]. In terms of defense, it has been widely accepted that the traditional approach based on byte-string signatures is increasingly ineffective, especially for new malware samples and sophisticated variants of existing ones. New techniques are therefore needed for effective defense against malware. Motivated by this problem, the paper investigates a new defense technique against malware. The technique presented in this paper is utilized for automatic identification of malware packers that are used to obfuscate malware programs. Signatures of malware packers and obfuscators are extracted from the CFGs of malware samples. Unlike conventional byte signatures that can be evaded by simply modifying one or multiple bytes in malware samples, these signatures are more difficult to evade. For example, CFG-based signatures are shown to be resilient against instruction modifications and shuffling, as a single signature is sufficient for detecting mildly different versions of the same malware. Last but not least, the process for extracting CFG-based signatures is also made automatic.","PeriodicalId":113767,"journal":{"name":"MILCOM 2017 - 2017 IEEE Military Communications Conference (MILCOM)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131723828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
