Some are spoofing attacks, Denial of service (DoS) attacks and its various forms (like ping attacks, smurfing etc), password sniffing, packet capturing along with traffic analysis and other wireless key cracking attacks. Many of these attacks steal someone's identity and use it for exploiting the victim or others by masquerading or forgery, made the network or computer system inoperable by interrupting normal services, created a back door for re-visits etc. In this paper we analyze some of these attacks and evaluate its effectiveness, concluding with some security recommendations.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115530391","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}

SVM provides a new approach to pattern classification and has been proven to be successful in fields such as image identification and face recognition. To apply SVM learning in partial discharge classification, data input is very important. The input should be able to fully represent different patterns in an effective way. The determination of features that describe the characteristics of partial discharge signals and the extraction of reliable information from the raw data are the key to acquiring valuable patterns of partial discharge signals. In this paper, data obtained from experiment is carried out in both time and frequency domain. By using appropriate combination of kernel functions and parameters, it is concluded that the frequency domain approach gives a better classification rate.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130827433","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 recent papers about DDoS attacks, especially the amplification attack looks for abnormal transaction that signals and eventually reports them. These methods may generate false positives or negatives and in turn can be quite dismal in its performance, in the wake of a real DDoS attack. This paper suggests a symmetric key exchange and hiding of a secret code in the UDP (user datagram protocol) packets. Any packet that has the secret code missing would be rejected. At first, the secure UDP protocol will be discussed and later, a similar method for the TCP (transmission control protocol) will be discussed. Finally the performance analysis is done to compare the overhead incurred.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125439784","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}

{"title":"Ascertaining of Copper Contamination from Various Sources in the Wafer Fab by Using VPD-TXRF Methodology","authors":"H. Abu Bakar, Z. Awang, W.A.A. Wan Razali","doi":"10.1109/SCORED.2007.4451384","DOIUrl":"https://doi.org/10.1109/SCORED.2007.4451384","url":null,"abstract":"Preventing and monitoring of Cu cross contamination become critical for the semiconductor industries since most of them are converting to mass-producing chips with copper (Cu), rather than aluminium (Al) as an interconnect element. Cu is a superior conductor of electricity, making it possible to shrink the electronic devices while further increasing performance. Presently, most of the Cu contamination emphasis on a wafer surface only using various methodologies. This in turn requires the need to improve the performance of analytical tool and to develop a new analytical measurement methodology for evaluating the levels of Cu contamination that might come from many sources in a wafer fab. In order to solve this problem, a new assessment methodology of using vapor phase decomposition and total X-ray fluorescence (VPD-TXRF) was introduced with the aim of establishing a trace elemental analysis. Currently, VPD-TXRF is mainly used as an analyzing tool to monitor Cu contamination on a wafer surface. However in this research, the same methodology is proof to be useful for measuring traces of Cu element induced from the other sources of contamination which is not necessarily from a wafer itself but also from the other sources in the whole fab. Gauge repeatability and reproducibility (GR&R) including component of variations study was applied in this research and the finding shows a positive results. A standard procedure and comparable sample also has been used which is ICPMS analyzing in purpose to set up a correlation with VPD-TXRF measurement data. Then this study aid to develop a valid procedure for Cu traces analysis, which served as a reference procedure to measure, monitor and control a Cu contamination. The final results validate this methodology as a distinguish method to measure a Cu contamination that come from many sources. Beside that, this methodology offers a cost saving since it uses a reclaim wafer as a sample preparation. Thus, this methodology is a key and can be used as process knowledge in accelerating advanced Cu interconnects development.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129534683","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}

Hikizu","doi":"10.1109/SCORED.2007.4451375","DOIUrl":"https://doi.org/10.1109/SCORED.2007.4451375","url":null,"abstract":"Deformable object manipulation is important for robots, especially home service robots. This is because unlike factory robots that handle rigid objects most of the time, these robots also need to be able to handle soft objects like clothes, rubber, paper etc. This paper proposes a unique tracing method for clothes manipulation by robots. The tracing method is used to reveal a second corner of a rectangular towel for spreading purposes, assuming that a first corner has been successfully grasped. Tracing in this paper's context is tracing the towel's edge, with the robot movement based on feedback from sensors. Using tracing method to find a second corner has been proven to be efficient in finding a second corner next to the first corner and not apposite it, resulting in the robot properly spreading the towel. The clothes manipulation system consists of two robot arms equipped with robot grippers, a CCD camera and an image processing board. Passive tracing is a method where the tracing gripper is static while the gripper holding the first corner maneuvers according to the feedback from sensors inside the static gripper so that it pulls the towel appropriately for the static gripper to trace the edge of the towel. Movement pattern is based on the sensors feedback inside the static gripper. Basically, the movement pattern is divided into two: inward the towel when the static gripper is too near to the edge of the towel and away from the towel when the gripper is too deep inside the towel. Force control is also applied to the static gripper during tracing so that it doesn't grip the towel too hard or vice versa. The CCD camera is used from time to time to check whether the static gripper has reached the second corner or not. Tracing experiments were conducted to evaluate the proposed method.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121577990","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}

However, period of transition may take years to complete which both protocols will coexist due to Internet services deployed are widely in IPv4. So, a successful IPv6 transition is depended on the compatibility with the large installed base of IPv4 hosts and routers, as well as maintaining security of the network from potential threats and vulnerabilities of both Internet protocols. This paper classifies potential security issues in the transition period and identifies prevention mechanisms to the problems identified. As dual-stacked host or network is the most simple IPv6 deployment any enterprise can settle for now, this paper focuses on possible implementation of distributed firewall in a dual-stacked environment which involves packet filtering at the edge router as well as the host-based firewall.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127764426","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}
