The input data tracking method, which was proposed before, prevents I-data, which are the data derived from the input data, being used as addresses. However, the rules to determine address injection attacks are vague, which produces many false-positives and false-negatives in detection results. Generally, the data used as an address consist of a base address and an address offset. We propose an architectural technique to prevent I-data overwriting B-data, which are the data used as base addresses in this paper. It dynamically recognizes the I-data and the B-data. Address injection is detected if I-data that are not B-data are used as addresses. We implemented the proposed technique on a Pentium-based Bochs emulator and investigated its detection capability. We believe that the technique is the most accurate injection detection technique proposed thus far","PeriodicalId":314915,"journal":{"name":"2006 12th Pacific Rim International Symposium on Dependable Computing (PRDC'06)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121693507","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 paper, we propose an outbound bandwidth based streaming model in which peers are layered according to their offered outbound bandwidth and are permitted to request data of peers from upper layers peers only. Based on the layered approach, a media data assignment algorithm for the subset of media data is presented to select qualified sending peers to ensure that they are received before their scheduled playback time. We also present two resolutions for request conflicts, which arise when there are more than one peer simultaneously requesting data from the same sending peer that can't afford outbound bandwidth for all requests. We evaluated the proposed streaming model through simulations. Experimental results show that streaming quality of the proposed streaming model is excellent and the properties of scalability as well as robustness are obtained even in a highly dynamic environment where peers join and leave frequently","PeriodicalId":314915,"journal":{"name":"2006 12th Pacific Rim International Symposium on Dependable Computing (PRDC'06)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125153426","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}

It contains two processor cores and realizes self-checking feature by comparing the processing results of the two processor cores. In order to overcome redundant input disagreement problem, two mechanisms have been implemented. The one is input data exchange mechanism used with bus comparison feature. The other is memory data comparison and copy mechanism. With the memory data comparison mechanism, input data comparison overhead can be reduced, which is especially useful for short period control task with many input data. The microprocessor utilizes 0.18mum CMOS process and integrates 512KB RAM and 25M transistors random logic in a 14.75mm x 14.75mm die.

Current anti-spyware tools use signatures to detect spyware programs. Over time, spyware programs have grown more resilient to this technique; they utilize critical areas of the system to survive reboots and set up mini-installers that re-install a spyware program after it's been detected and removed. Since existing anti-spyware tools are stateless in the sense that they do not remember and monitor the spyware programs that were removed, they fail to permanently remove these self-healing spyware programs. This paper proposes STARS (stateful threat-aware removal system): a tool that at run time intercepts critical system accesses and assures removed spyware does not re-install itself after a successful removal of spyware program in the system. If a re-installation (self-healing) is detected, STARS infers the source of such activities and discovers additional \"suspicious\" programs. Experimental results show that STARS is effective in removing self-healing spyware programs that existing anti-spyware tools fail to do","PeriodicalId":314915,"journal":{"name":"2006 12th Pacific Rim International Symposium on Dependable Computing (PRDC'06)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134137723","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 paper, we develop two-dimensional software reliability models with two-time measures and incorporate both of them to assess the software reliability with higher accuracy. Since the resulting software reliability models are based on the familiar non-homogeneous Poisson processes with two-time scales, which are the natural extensions of one-dimensional models, it is possible to treat both the time data simultaneously and effectively. We investigate the dependence of test-execution time as a testing effort on the software reliability assessment, and validate quantitatively the software reliability models with two-time scales.

Combination of ECC, particularly SECDED, with a redundancy technique can effectively tolerate a high number of defects. While SECDED can repair a defective cell in a block, the block becomes vulnerable to soft errors. This paper proposes SEVA, an original soft-error- and variation-aware cache architecture. SEVA exploits SECDED to tolerate variation-induced defects while preserving high resilience against soft errors. Information about the defectiveness and data dirtiness is maintained for each SECDED block. SEVA allows only the clean data to be stored in defective (but still usable) blocks of a cache. An error occurring in a defective block can be detected and the correct data can be obtained from the lower level of the memory hierarchy.

Process failures are assumed to be manifested as missing messages (fail-silent assumption). Whenever a node detects a change in the membership status of any process, it broadcasts its opinion about the membership status of all processes. This information is broadcast only by nodes that detect a change of local membership status. The protocol is implemented in a distributed embedded system with TTCAN-communication.
