Messages are exchanged to inform the other vehicles about emergency situations such as-safety alerts, and location privacy. Due to the usage of an insecure wireless medium, malicious activities in vehicles, i.e., illegal use of the false messages, can astray other vehicles. Security in communication among the vehicles can be provided by encrypting the messages using various security keys. However, it has been found from the literature that existing schemes for secure communication require large key size, and therefore may these schemes may not be applicable to smart cities. To address these issues, a secure message communication scheme among vehicles based on elliptic curve cryptography (ECC) is proposed. The proposed scheme needs smaller key size leading to mathematically simple and cost effective solution. Furthermore, the scheme provides mutual authentication, confidentiality, and forward secrecy. Security analysis prove that the proposed scheme is suitable to be adapted in smart city environment.","PeriodicalId":340958,"journal":{"name":"2016 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133342603","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}

Global Navigation Satellite Systems (GNSS) based code allocation is a great solution. It tessellates the geographic region to be covered into regular hexagonal quantization cell. All users access to their location information at marked time instances through GNSS. The transmission sequences are pre-assigned to the location cells and then dynamically assigned to the users. It also proposed a concept of sequence reuse that is akin to frequency reuse. A drawback of GNSS-based code allocation is the average user throughput (AUT) is relatively low. Transmission sequence reconstruction and allocation (TSRA) based on GNSS-based code allocation is proposed. Firstly, in each superframe T, each user acquires user irrepressibility (UI) sequence according to GNSS-based mechanism in the first period to obtain the information of neighbors in the same cell cluster; users in different direction use half of the superframe T respectively. Secondly, users reconstruct a set of UI sequences according to the number of neighbors in the same cell cluster. Then, users acquire a reconstructed sequence according to the order of the users' first successful “1” in the first period. The performance of TSRA is compared with GNSS-based code allocation by ns-2 with the vehicle mobility data from the Simulation of Urban Mobility (SUMO). The simulation results show that the AUT of TSRA is better than GNSS-based code allocation in a relatively sparser distributed network.","PeriodicalId":340958,"journal":{"name":"2016 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116324632","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}

After the summary of all kinds of normal mode decomposition method and the combination with a new kind of non-linear signal processing transformation method Warping transformation, a new method of multi-path separation for shallow water wideband acoustic signal based on Warping transformation was proposed. With the transmitted signals limited on a time window and the received signal of the processing of pulse compression, the processed received signal had a processing of warping transform and time-frequency analysis, in this way, a method which has wide applicability and high precision on decomposition and information ex-traction of the normal mode was achieved. Finally, a conclusion was verified through a simulation, the new method can be used in the normal mode separation of the chirp transmitted signal with a certain length of time, and has a greater advantage compared with conventional Warping transform processing results. Meanwhile, the separation signals extracted were substantially identical with the original signal after inverse operation restore, which proved the accuracy of this method.","PeriodicalId":340958,"journal":{"name":"2016 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128704850","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}
