Such unauthorized file accesses may bring on the user data leakage or other threats. In this paper, we propose a novel light-weight hardware-assisted hyper visor, namely FVisor, to thwart such unauthorized file accesses. FVisor has three distinct advantages over existing hyper visor/host-based approaches: preinstalled commodity OS compatibility, non-by passable interception of files accesses and block level file-ware. Unlike typical hyper visors, deploying FVisor does not require OS reinstallation. FVisor intercepts the instruction-level interactions between the OS and the underlying hardware, instead of traditional API hooks. FVisor thus can manipulate the file accesses at the hyper visor layer instead of the OS layer, which is subvert able for the privileged malware. Besides, FVisor reconstructs the file system structures within the hyper visor at the block level without depending on the OS APIs. Our functionality evaluation shows FVisor is a feasible way to impede unauthorized file accesses while the performance evaluation shows desktop-oriented workloads achieve 93.57% of native speed on average.","PeriodicalId":258990,"journal":{"name":"2014 IEEE 17th International Conference on Computational Science and Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123281797","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}

Android uses the permission system to notice the user during installation about what permissions it will receive. However, according to related research, most users have poor understanding of permissions, and will accept the prompt directly. Over privileged applications will expose users to unnecessary permission warnings and increase the impact of a bug or vulnerability. In order to reduce user's trouble and avoid application over privilege, we focus on permissions for a given application and examine whether the application description provide any indication for why the application needs a permission. We propose an android semantic permission generator (ASPG) to understand what permissions an application needs from user's perspective. Our ASPG can get the semantic permissions based on the application description. Besides, ASPG will further tailor the semantically unrelated permissions. We analyze ten popular applications using the ASPG, finding that they all contain semantically unrelated permissions. After tailoring the semantically unrelated permissions, most of applications can run normally. Experimental results show ASPG is feasible. In addition, we provide a specification to support our ASPG better when an application runs abnormally.","PeriodicalId":258990,"journal":{"name":"2014 IEEE 17th International Conference on Computational Science and Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122299489","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 this research, Solid Works 3D drawing software is used as the structural design and Max Well magnetic field analysis software is used to simulate the lines of magnetic force toward the innovation design \"semi-active spiral flow channel magneto rheological damper\" to improve the heat dissipation and the problem of precipitation. The Performance test of semi-active spiral flow channel magneto rheological damper uses ball screw and AC Servo Motor as actuator, the servo control system's function of displacement recorder and load cell as recorder of damping force. The syringe-type MR damper is an innovative design, the spiral flow can not only increase the length of the flow channel in a fixed distance, but also changes the excitating paramagnetic particles direction to be vertical with the direction of flow, and thus increases the ultimate shear strength of MRF. Without applying magnetic field, the syringe-type MR damper can generate the maximum damping force of 153N. When the current is 0.5A, the maximum damping force is about 301N, when the damping force adjustment coefficient is 1.97(=301/153), the damper is with high range of adjustable damping force. Most importantly, this design establishes a simple structure with lower cost.","PeriodicalId":258990,"journal":{"name":"2014 IEEE 17th International Conference on Computational Science and Engineering","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126077131","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}

An SDN logically centralizes the control plane of network entities at the controller level. To achieve scalability, reliability, and availability, it is inevitable for the control plane to be configured as physically distributed. However, current deployments adopt a single SDN controller mainly due to problems of management complexity and costly maintenance. In this paper, we present a novel SDN architecture called a Wireless Proxy Controller (WiPCon) in order to increase the control plane efficiency of wireless networks. WiPCon involves a proxied control plane for wireless access points (APs) supporting SDN. It has a hybrid architecture in that the proxy SDN controller within the AP performs some of the main SDN controller roles, such as responding to specific network events, collecting wireless information, and local cooperation, although the control plane of the APs moves to the main SDN controller. Even though a single main SDN controller is used, WiPCon has robustness when it comes to network partitions or control bottlenecks, and flexibly copes with scalability issues that originate from dense deployment of APs. We analyzed various network factors through a preliminary implementation of WiPCon. Consequently, we verified that the proposed architecture efficiently supports control scalability and considerably reduces control overhead of the main SDN controller.","PeriodicalId":258990,"journal":{"name":"2014 IEEE 17th International Conference on Computational Science and Engineering","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114192805","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}

By using erasure code, the original data is encoded into blocks which are stored on different nodes. When one node fails, the lost data block needs to be recovered by transmitting a large number of data from helper nodes, which is called repair. Intersecting zigzag sets codes (IZS codes) and hierarchical code are two kinds of codes which reduce the bandwidth overhead in repair. IZS codes reduce the amount of data uploaded by each helper node, while hierarchical codes reduce the number of nodes participating in repair. In this paper, we propose a class of code called intersecting zigzag sets-hierarchical code (IZ2SHC code) to unify them together. IZ2SHC code decreases repair degree as hierarchical code and reduces repair overhead compared with the latter. Besides, it realizes exact regeneration of the failed data, and need not encode in helper node during the repair, which reduces disk read cost for helper node when transferring data in repair.","PeriodicalId":258990,"journal":{"name":"2014 IEEE 17th International Conference on Computational Science and Engineering","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116246405","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}

Due to the existence of an error-correcting word (ECW) generated by MBE and RB encoding, the RB multiplier generates an additional RB partial product rows. An extra RB partial product accumulator (RBPPA) stage is needed for 2n-b RB MBE multiplier. The higher radix Booth algorithm than radix-4 can be adopted to reduce the number of partial products. However, the Booth encoding is not efficient because of the difficulty in generating hard multiples. The hard multiples problem in RB multiplier can be resolved by difference of two simple power-of-two multiples. This paper presents a new radix-16 RB Booth Encoding (RBBE-4) to avoid the hard multiple of high-radix Booth encoding without incurring any ECW. The proposed method leads to make high-speed and low-power RB multipliers. The experimental results show that the proposed RBBE-4 multiplier achieves significant improvement in delay and power consumption compared with the RB MBE multiplier and the current reported best RBBE-4 multipliers.","PeriodicalId":258990,"journal":{"name":"2014 IEEE 17th International Conference on Computational Science and Engineering","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116743957","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}
