Although this new computing paradigm brings many advantages like utility computing model but the design in not flawless and hence suffers from not only many known computer vulnerabilities but also introduces unique information confidentiality, integrity and availability risks as well due its inherent design paradigm. As a result the digital forensics, which relies heavily on physical access to computing devices and applications logs, has become a biggest challenge in cloud environments due to the non-availability of physical access to computing devices and applications logs. As we will see this paper highlights many of the digital forensics issues in the cloud environments and tries to address some of these forensics issues by identifying possible Syslog or Snort logs that can help in detecting cloud attacks or conducting digital forensics in cloud environments by analyzing logs generated by an open source cloud computing Eucalyptus software. As we will see in the paper we neither had access to Eucalyptus logs dataset nor it was known that any such dataset exist that could be analyzed offline for digital forensics purposes. Thus we generated our own dataset by attacking Eucalyptus with many of the known cloud attacks and then analyzing the resultant dataset to identify possible log entries that could identify cloud attacks or help in conducting digital forensics in cloud environments.","PeriodicalId":101923,"journal":{"name":"2011 Frontiers of Information Technology","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452410","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}

During the development of such technologies operation of the devices/protocols was the main concern and the security aspect was ignored. But the losses that occur due to security breaches resulted in security conscious designs. The direction of technological advancement is also towards more functionality in less area. In such cases security is usually the last preference. There is also more advancement in chip fabrication per unit area that brings the concept of system on chip (SOC). So to take the advantage of small fabrication per unit area for security enhancement we propose the architecture of modular arithmetic unit (MAU) as part of the new SOC in order to implement cryptographic algorithms in an efficient manner. MAU is designed keeping in view ease of interfacing with any processor on SOC. Thus cryptographic algorithms that are based on modular arithmetic can be written in high level language and executed on processor of SOC. MAU is implemented on Xilinx Spartan 3 which shows flexibility, scalability and less area. The implementation results show area consumption of 1500 slices.","PeriodicalId":101923,"journal":{"name":"2011 Frontiers of Information Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131804280","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}

These are intelligent radios having the capability of sensing the radio environment and reconfiguring the operating parameters dynamically. Recently cognitive radios are considered for ad hoc environment. Cognitive radio ad hoc network have several unique features other than inherited features of ad hoc network like distributed multi-hop architecture, variant network topology and opportunistic spectrum availability. It is required for cognitive radio to find unutilized portion of the spectrum more accurately for successful deployment of cognitive radio ad hoc networks. In cooperative spectrum sensing, multiple cognitive radio users cooperate to detect the presence or absence of primary user to improve the detection performance. Ad hoc networks are dynamic in nature and have no central entity for data fusion. Therefore cognitive radio ad hoc networks need fully distributed cooperative spectrum sensing. In this paper, a gradient based fully distributed cooperative spectrum sensing is proposed for cognitive radio ad hoc networks. The proposed scheme is analyzed from the perspective of reliable sensing and energy consumption. Simulation results show the effectiveness of the proposed scheme.","PeriodicalId":101923,"journal":{"name":"2011 Frontiers of Information Technology","volume":"415 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115924670","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}
