The one tap ZF-equalizer and equivalent OFDM presentation of SEFDM signals is used to perform channel correction. Demodulation is done using trellis based demodulator. The proposed receiver structure has relatively low computation complexity compared to SEFDM demodulators which use sphere decoder. Thus the proposed receiver is applicable to SEFDM signals with high number of subcarriers as in WiFi, LTE, DVB-T2 systems. The resulting BER performance of SEFDM in various LTE fading channels using the proposed receiver is comparable with performance of QPSK OFDM with the same number of subcarriers. The analysis is done under assumption of perfect channel knowledge.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"28 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":"130062232","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}

At the same time, the homology analysis of malicious code is also an important part of studying the groups behind different APT (Advanced Persistent Threat) attacks. At present, homology identification still relies on manual analysis and security experts' experience in the anti-malware industry. In addition, research on large-scale malicious code automated homology analysis is still insufficient. The method proposed in this paper is to solve the problem of large-scale malicious code homology automatic analysis, and hope to provide auxiliary information for discovering the group behind the APT attack. In this paper, we collected samples of different APT groups from public threat intelligence and proposed a novel approach to classify these samples into different APT groups to further analyze the homology of malware. We combined the CFG (Control Flow Graph) of the malicious code function and the disassembled code of the stripped malware to generate the embedding, i.e., a numeric vector, which formed a function feature database of the APT group, and presented a neural network model used for APT group classification. We have implemented our approach in a prototype system called MCrab. Our extensive evaluation showed that MCrab could produce high accuracy results, with few to no false positives. Our research also showed that deep learning can be successfully applied to malware homology analysis.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"136 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":"123587178","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}

This paper investigates simultaneous wireless information and power transfer (SWIPT) in a NOMA relaying system. The data is transferred from a source to two end terminals among which the one close to the source acts as a relay employing decode-and-forward protocol to assist the far-end one. In order to simultaneously harvest the energy and information processing at relay node, power-splitting relaying (PSR) and time switching-based relaying (TSR) protocols are sequentially considered. Outage probability and ergodic rate of both protocols are firstly analyzed to realize the impacts of various parameters including energy harvesting time, power splitting ratio, energy harvesting efficiency, source data rate, and the distance between the source and the relay node. Numerical results are then provided to validate the analytical findings. It is shown that the PSR outperforms the TSR at normal SNR regime in terms of throughput and ergodic rate.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"12 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":"126545867","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}

We model and formulate the issue as a max-min fairness power control problem, which needs to be considered in order to provide good experienced service for users in the system. By exploiting the special properties of the solution, we are able to propose a very simple power control algorithm with complexity $mathcal{O}(M(N+M))$ where $M$ and $N$ are the number of users and base station antennas respectively. In addition, only the estimated channel response and maximum transmit power of each user are required as input information. We implement the proposed algorithm on a record-playback massive MIMO testbed to verify the performance in real environment. The result show that the received signal quality of the worst user is much more improved, and all users experience roughly the same level of quality of service. In addition, simulation is carried out to confirm the advantage of the proposed scheme in term of minimum spectral efficiency.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"98 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":"127505220","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}

In practice, attributes usually have a certain lifespan. The existing time-based access control methods directly relate attribute keys to time. Thus, under the constraint of fine-grained time, when the attribute expires, the update of key and policy adds a large additional burden to the data user and owner. In this paper, we propose a dynamic attribute-based access control scheme to set a fine-grained valid time period for each attribute, which not only facilitates dynamic data sharing, but also enables flexible attribute revocation. We use smart contract to set valid time period for attributes. It provides smart management on users' attributes and avoids the waiting time of CSP caused by manual operations. We also introduce trapdoor that are indirectly related to time and proxy decryption method to reduce computational cost on data owners and users. Extensive security and performance analysis shows the security strength and effectiveness of the proposed scheme.","PeriodicalId":127412,"journal":{"name":"2019 26th International Conference on Telecommunications (ICT)","volume":"3 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":"115541608","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}
