Although the technique combats well against replay attacks, however, it is vulnerable to desynchronisation attacks. The later type of attacks, if framed and mounted against the crucial update mechanisms, which occur in mobile satellite communication systems, can lead to permanent Denial of Service (DoS) conditions. In this context, the authentication protocol initially proposed by Lee et al. [1] has emerged as the defacto protocol and forms the basis for various other authentication protocols developed since then.In this paper our contribution is two-fold. The first part of the paper presents an analysis of the authentication protocol [1], which reveals that the protocol is fundamentally susceptible to two attacks: impersonation attack and desynchronisation attack. To overcome these susceptibilities, in the second part of the paper, a new authentication protocol is proposed which incorporates a resynchronization phase. The paper demonstrates that the proposed solution is robust to impersonation attacks as well as to permanent DoS conditions caused by desynchronisation attacks. Moreover, the proposed solution is expected to find its application to address the desynchronisation issue found in numerous other recently published enhanced authentication protocols.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129735315","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}

Bories","doi":"10.1109/WCNCW.2019.8902737","DOIUrl":"https://doi.org/10.1109/WCNCW.2019.8902737","url":null,"abstract":"Densification of mobile networks using small cells (SCs) is a promising approach to achieve the forecasted 1000x growth in capacity for next generation wireless communication systems. However, a major impediment of dense SC network is the low signal-to-interference-plus-noise ratio (SINR) regime, notably in uncoordinated time-division duplexing (TDD) systems in sub-6GHz bands. To circumvent this issue and to enhance the performance of the physical (PHY) layer, hybrid beamforming (HBF) solutions involving both analog and digital stages are necessary. HBF technologies provide interference rejection through analog filtering prior to quantization, spatial multiplexing and require lesser radio-frequency (RF) chains and analog-to-digital converters (ADCs). Conversely, digital beamforming (DBF) performance saturates because of high interferers (blockers) and restricted ADC dynamic range. Moreover, HBF RF circuitry could be further simplified by the use of phase-only weights in analog beamforming (ABF) stage. However, this would be at the cost of making the SINR optimization problem non-convex. Existing sumrate results amalgamating quantization noise consist of lower bounds obtained by distortion factor approximation and worst-case distribution assumption. In this paper, we propose a relaxation approach to phase-only beamforming which allows for a straightforward solution using off-the-shelf interior point algorithms. Rather than directly comparing it in terms of sumrate, we compare it first in terms of SINR, as a function of an algebraic angle between the interferer and the user, with a state-of-the-art local convergence method. Further to this, we include an ADC model to the existing lower bound sumrate results, and analyze various solutions in a sub-6GHz multi-user uplink scenario.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127001618","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}
