This paper builds up a performance management system based on the one-class-support vector machine (OCSVM) and k-means clustering algorithm, which achieves not only the automatic detection of network anomalies but also the clustering of the anomalies with different levels. The OCSVM detects the anomalies by solving an optimal problem to separate the nominal data from the anomalies; these detected anomalies are then classified into minor, medium and severe levels using k-means clustering. The real telecommunication performance data are employed in this paper for the investigation, and the numerical results demonstrate the promising performance of this system.","PeriodicalId":167937,"journal":{"name":"2008 Third International Conference on Dependability of Computer Systems DepCoS-RELCOMEX","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132306110","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}

E-commerce and e-work is still at its embryonic stages, however, the annual rate of increase suggest that in very few years this share will have grown dramatically. Thus, it is time to get prepared. The aim of the present paper is to present a new maritime intelligent workplace based weather information system and decision support for high-speed maritime transport. It has been achieved by linking fixed/mobile communications with navigation/positioning, efficient transmission and delivery over the geo-information network. These services will allow the shipmaster to have seamless access to, and interaction with intelligent, customised (route based) rich content multimedia information on the efficient and safe navigation passage for passengers, freights and the environment both on board ship and inland.","PeriodicalId":167937,"journal":{"name":"2008 Third International Conference on Dependability of Computer Systems DepCoS-RELCOMEX","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124478138","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 this reason nowadays network security and dependable operation has become a major priority for design and implementation. Looking for powerful means network engineers started to often use computer simulation technique as a way for better understanding and development of complex computer systems. Therefore, plenitude of specialized development initiatives appeared in last few years. Currently network simulators are tools useful not only for creating new and better protocols, but also become money savers. By extending their functionalities e.g. post-processing capabilities for evaluating security and dependability metrics they turn out to be a fundamental state of the art network management platforms. This paper presents the information system, proposes metrics definitions, and describes the procedure of their evaluation using a simulator and a post-processing module.","PeriodicalId":167937,"journal":{"name":"2008 Third International Conference on Dependability of Computer Systems DepCoS-RELCOMEX","volume":"59 22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116730789","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}

Last years many authors have presented that almost all contemporary cryptographic algorithms are susceptible to the fault analysis. Unfortunately, only a few propositions to overcome this threat have been proposed. Moreover most works focus on secret key cryptosystems (e.g. AES, RC6, Blowfish) and the RSA encryption and signing algorithm. On the other hand much less attention have been paid to other signature and identification schemes.In this paper we will investigate the fault attack on the ElGamal signature scheme. We briefly present two attacks on this scheme and propose a modification that ensures immunity to transient and permanent faults. This is achieved without using comparisons, at cost of increased computational overhead similar to signature verification.","PeriodicalId":167937,"journal":{"name":"2008 Third International Conference on Dependability of Computer Systems DepCoS-RELCOMEX","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126663813","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 proposal allows us to decrease an amount of secret key information that should be sent from its generator to the network participants. The considered approaches and key pre-distribution schemes correspond to peculiarities of mobile networks owing to the facts that participants should'n implement asymmetric cryptographic systems and the public key certification service; moreover the communication phase don't suppose any interconnection with trusted authority key distribution center.","PeriodicalId":167937,"journal":{"name":"2008 Third International Conference on Dependability of Computer Systems DepCoS-RELCOMEX","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121752827","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 proposed approach we determine cooperation and autonomy abstractions and consider them in the context of three basic relations (sub-ordination, tolerance, collision).
