This paper highlights security concepts relevant to using SOA as a foundation for a Common Operating Environment (COE), i.e., a set of infrastructure and common services for developing and executing applications across multiple platforms. We present and motivate security needs, tradeoffs, and solutions in the various layers of a SOA-based COE, including 1) the network, 2) computational platforms, and 3) the common software infrastructure consisting of a SOA stack, common services, and applications. We also discuss cross cutting aspects of security such as survivability, transparency, flexibility, specificity, reuse, and assurance. We then explore security standards and requirements for mission-critical systems developed on top of a SOA-based COE and security technologies that are candidates for satisfying the requirements. The paper closes with a set of recommendations and steps forward for both research into and implementation of security in a SOA-based COE.","PeriodicalId":126022,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122041899","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}

From the designers' perspective, the most natural way to specify the task criticalities is by expressing the reliability requirements at task level, without having to deal with low level decisions, such as deciding on which FT method to use, where in the system to implement the FT and the amount of resources to be dedicated to the FT mechanism. Hence, it is extremely important to devise methods for translating the high-level requirement specifications for each task into the low-level scheduling decisions needed for the FT mechanism to function efficiently and correctly. In this paper, we focus achieving FT by redundancy in the temporal domain, as it is the commonly preferred method in embedded applications to recover from transient and intermittent errors, mainly due to its relatively low cost and ease of implementation. We propose a method which allows the system designer to specify task-level reliability requirements and provides a priori probabilistic scheduling guarantees for real-time tasks with mixed-criticality levels in the context of preemptive fixed-priority scheduling. We illustrate the method on a running example.","PeriodicalId":126022,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114399861","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 architecture provides both spatial and temporal partitioning, thus enforcing enough separation for the critical applications. With temporal partitioning, each application is allowed to run only within predefined time slots, allocated on each processor. The sequence of time slots for all the applications on a processor are grouped within a Major Frame, which is repeated periodically. We assume that the safety-critical applications (on all criticality levels) are scheduled using static-cyclic scheduling and the non-critical applications are scheduled using fixed-priority preemptive scheduling. We consider that each application runs in a separate partition, and each partition is allocated several time slots on the processors where the application is mapped. We are interested to determine the sequence and size of the time slots within the Major Frame on each processor such that both the safety-critical and non-critical applications are schedulable. We have proposed a Simulated Annealing-based approach to solve this optimization problem. The proposed algorithm has been evaluated using several synthetic and real-life benchmarks.","PeriodicalId":126022,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121981557","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}

This paper describes the software infrastructure for CARS, based on our Wrapping approach to knowledge-based integration. It allows us to share code between simulations for algorithm development and instrumented experiments with the real cars in a real environment. It also allows us to use many computational resources during algorithm development, and then to ``compile-out'' all resources that will not be needed, and all decision processes that have only one choice, in a given real environment. The instrumented experiment is run in parallel with the simulation, and the differences can be used to adjust the models. We describe the autonomic agent infrastructure, i.e., the ``enabling software'' processes: health and status, local activity maintenance, and fault management. These processes can be very resource-hungry in any agent, and our use of simulations allows us to study trade-offs directly between safety and capability in the agents, to tune the trade-off at deployment time, based on what we know or expect of the environment, and to monitor and change those assumptions when necessary.","PeriodicalId":126022,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133797967","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}
